Why does a container become the IT closet?
A container becomes the IT closet when a building cannot host one. A shipping container is a sealed, lockable steel shell that takes spray-foam insulation, redundant cooling, UPS power, clean-agent fire suppression, and structured cabling, then sits on a gravel pad as a self-contained server room. It is the fastest way to put hardened compute where there is no room to spare inside the building.
Server rooms have always lived in spare offices and basement closets because nobody planned for the IT footprint when the building went up. That works until the building floods, the HVAC quits at midnight, or the operation moves to a remote site that does not have a building at all. A shipping container reframes the problem. The same 8-foot-wide steel box that survives an ocean crossing in a storm makes a sealed, lockable, fully serviceable IT shelter that can sit on a gravel pad behind the school, beside the pumping station, or at the back of the hospital service yard.
Van Blanc has been delivering containers across Ontario since 1995. The IT-shelter use case has grown from a niche request to a regular order in the last few years, driven by three forces: edge computing pushing compute closer to the data, aging buildings that cannot accept another HVAC penetration, and capital projects that need a working server room six months before the building goes up. Paul LeBlanc, who founded Van Blanc in 1995, puts it plainly: “Industrial customers ask for cargo-worthy steel because they need the structure to hold modifications for 20 years of service life, not 5. The container is the shell. The fit-out is the data centre, and the steel has to outlast it.”
What a container IT shelter is, technically
A container server room is a Type-1 ISO freight container (typically a 20ft or 40ft high cube) outfitted as a self-contained data hall. The fit-out covers the same insulation and steel-cutting work we do at the yard including spray-foam insulation, vapour barrier, interior wall panels, ESD-rated flooring, redundant air conditioning, UPS power, clean-agent fire suppression, fibre and copper structured cabling, environmental monitoring, CCTV, and biometric or card access. Most builds target a usable rack capacity of 4 to 12 racks at IT loads of 3 to 5 kW per rack. The standard reference for the cabling, cooling layout, and rack geometry is ANSI/TIA-942-C Telecommunications Infrastructure Standard for Data Centers, which since the 942-A revision explicitly accommodates outdoor modular containers.
The shipping container is not novel here. Sun Microsystems shipped the Project Blackbox in 2006, Google ran container-based data halls for years, and modular container data centres now ship as full Tier III ready products from vendors like Stulz, Schneider Electric, Rittal, and Dell. What is new is the cost curve sliding down to where a small Ontario school board, a municipal water utility, or a regional clinic can buy the steel from a local supplier, contract a Canadian integrator, and end up with a working IT shelter for the price of two years of colocation rent.
How many racks fit in a 20ft or 40ft container?
Container sizes set the rack count. A 20ft holds 4 racks in a single front-service row, a 40ft holds 8 to 10 racks in a hot-cold aisle, and a 40ft high cube holds 10 to 12. The first question on every server-room build is how many racks fit inside. The honest answer depends on whether you want a working room, with aisle space and service clearance, or a packed steel box that is impossible to maintain. Industry build standards have settled on the following:
| Container | External | Usable racks | Aisle layout | Typical IT load |
|---|---|---|---|---|
| 20ft standard dry | 6.06 m × 2.44 m × 2.59 m | 4 racks | Single row, front-service only | 12 to 20 kW total |
| 20ft high cube | 6.06 m × 2.44 m × 2.90 m | 4 to 6 racks | Single row, room for in-row CRAC | 15 to 25 kW total |
| 40ft standard dry | 12.19 m × 2.44 m × 2.59 m | 8 to 10 racks | Hot-cold aisle, two rows of 4 to 5 | 30 to 50 kW total |
| 40ft high cube | 12.19 m × 2.44 m × 2.90 m | 10 to 12 racks | Hot-cold aisle, two rows of 5 to 6 | 40 to 60 kW total |
| 45ft high cube | 13.71 m × 2.44 m × 2.90 m | 12 to 14 racks | Hot-cold aisle, extra service area | 50 to 70 kW total |
The extra foot of headroom in a high cube matters more than most buyers realise. A standard-height box measures 8 feet 6 inches on the outside, which leaves about 7 feet 10 inches of usable interior height once insulation, vapour barrier, ceiling plenum, and finished flooring are installed. A full-height 48U server cabinet is 7 feet 5 inches tall. The math works, but only just. A high cube gives you a full 9 feet 6 inches external, which translates to about 8 feet 10 inches inside with the same build-out, leaving room for overhead cable trays, in-row sensors, and the lighting cans that the electrician needs to install to keep the build code-compliant.
Choosing 20ft vs 40ft for a server room
- 20ft works for: A single school site IT closet, a SCADA control room at a wellhead, a backup comms shelter for a hospital, a network point of presence for a regional internet provider, or a 4-rack edge node.
- 40ft works for: A school board head-end serving 30 buildings, a municipal data hall that runs water, transit, traffic, and finance systems, a mining-camp IT shelter that holds production servers and the satellite uplink, or a small regional colocation.
- 45ft works for: Anything where you want the aisle space to walk a service tech through with a cart and never have them turn sideways. Increasingly common on industrial sites with 24/7 ops.
- Two 20ft side-by-side beats one 40ft when: The site has tight access for delivery, or when the owner wants production and DR (disaster recovery) physically separated in different boxes on different power feeds.
How much cooling does a container server room need?
A container server room needs cooling sized to the full IT load plus one spare unit, the N+1 rule. Plan on 3 to 5 kW per rack for mixed gear, more for compute-dense racks. Cooling is where most container builds either pay for themselves over 20 years or fail in the first summer. The load is heavier than buyers expect. A modern 1U rack server idles at 200 to 400 watts and runs flat-out at 600 to 1,000 watts. A 42U rack of mixed gear, half-populated, lands at 3 to 5 kW. A fully populated rack of compute or GPU lands at 10 to 30 kW. Inside a sealed steel box with no thermal mass, every watt of IT load is a watt of heat that has to leave the room.
The standard data centre reference, ASHRAE TC 9.9 Thermal Guidelines for Data Processing Environments, sets an allowable inlet temperature of 18 to 27 degrees Celsius for typical IT equipment, with a recommended sweet spot of 20 to 25 degrees. To hold that band inside a 40ft container loaded to 30 to 40 kW of IT load on an Ontario August afternoon, you size the cooling at the load plus a redundancy factor. The convention is N+1: enough cooling units to handle the full IT load with one unit out of service.
N+1 cooling, worked out for a 40ft high cube
If the IT load is 40 kW and you specify two cooling units at 25 kW each, you have N+1 redundancy. Either unit alone covers the room. Both running, the duty cycle drops, the compressors last longer, and the building automation system can rotate them on a weekly schedule so neither gets stuck idle and seized. In-row CRAC units (precision air conditioners that sit between racks, drawing hot exhaust from the rear and pushing cold air out the front) are the most common choice for container builds because they fit the geometry. Roof-mounted condensers vent the heat outside the box. Below about minus 20 degrees Celsius, the system needs winterisation: head pressure controls, crankcase heaters, and refrigerant charge tuned for cold-weather operation. Ontario winters do this every year. Build it in.
Three cooling architectures show up on Ontario container builds:
- In-row precision CRAC. The most common. Two or three vendor-grade in-row units, R-410A or R-32 refrigerant, EC fans, condensate pumps, hot/cold aisle containment with vinyl curtains or full panels. Suitable for IT loads up to 60 kW in a 40ft.
- Rear-door heat exchanger. A chilled-water coil mounted on the back of each rack that absorbs the hot exhaust before it leaves the rack. Tighter footprint, lower air-side energy, but requires a chilled water loop and a roof-mounted dry cooler. Used in higher-density builds.
- Direct liquid cooling. Cold plates on the CPU/GPU, manifolded to a coolant distribution unit (CDU), with a chilled water loop to the dry cooler. The only path for AI workloads at 30 to 50 kW per rack. Still rare in Ontario container builds, but coming.
The condenser placement matters for delivery. National competitors ship the container with the cooling pre-installed and the condensers strapped to the roof. When the container goes on a tilt-deck truck for placement, those condensers are coming off the truck before the lift, then craned back into position on site. Plan the roof penetrations and the lifting eyes during the build so the install does not become an improvised crane day. Van Blanc supplies the steel and coordinates with the integrator on the penetrations during the modification phase, before the box leaves our yard.
What power and UPS does a container IT shelter need?
A container IT shelter needs three-phase utility power, a double-conversion UPS sized above the IT load, a dedicated battery rack, rack PDUs, and usually a standby generator. Container server rooms run on 208/120 V or 480/277 V three-phase, depending on the IT load and the site service. The Canadian Electrical Code, CSA C22.1, governs everything from the cable sizing to the bonding of the steel container shell. Ontario adds local amendments administered by the Electrical Safety Authority (ESA). The honest read: every container server room built for occupation in Ontario needs an ESA permit, an ESA inspection, and equipment carrying CSA or cUL marks. The work is straightforward for a licensed electrician with data-centre experience, but it is not optional.
Power architecture for a typical container IT shelter
- Utility service: 200 to 600 A at 208/120 V or 480/277 V, fed from a pad-mount transformer or the building MDP, terminated in the container at a main distribution panel.
- UPS: A double-conversion online UPS sized at 110 to 125 percent of the IT load, with battery runtime of 10 to 30 minutes (long enough for generator transfer or graceful shutdown). Modular UPS architectures let you start at 20 kW and add 20 kW power modules as the load grows.
- Batteries: Lithium-ion is becoming the default. Smaller footprint than valve-regulated lead-acid (VRLA), longer service life (10 to 15 years vs 4 to 6), tighter thermal envelope. Either way, the battery rack lives in its own section of the container with dedicated ventilation and a separate fire-detection zone.
- PDUs: Rack-mount, metered or switched, with C13/C19 outlets feeding the IT gear. NEMA L6-30 or IEC 60309 inlets feeding the PDU from the rack power circuit.
- Generator: Standby diesel or natural gas, sized at the full IT plus mechanical load plus margin. Lives outside the container on its own pad with the fuel system. Auto-transfer switch in the container, ATS interlocked to the UPS.
- Continuous load rule: Sustained IT load is treated as continuous per CSA C22.1. Sized circuits cannot exceed 80 percent of the breaker rating unless the equipment is explicitly rated and installed for 100 percent continuous operation. Plan for this at design time, not at the inspection.
The battery rack is the part most non-IT contractors get wrong. Lithium-ion batteries have failure modes that need their own dedicated detection (off-gas sensors, separate aspirating smoke detection) and their own thermal management. Putting the UPS, the IT gear, and the battery string in the same airflow zone, behind the same cooling units, on the same fire-suppression release, is a build that passes a quick inspection and fails ten years later when the battery rack vents and the smoke detector trips the clean agent over the whole room. Separate zones. Separate detection. The integrator earns the design fee here.
Which fire suppression: FM-200 or FK-5-1-12?
Container server room fire suppression means a clean-agent gas system, not sprinklers. FK-5-1-12 (Novec 1230) is the current Ontario default because it matches the older FM-200 on performance with a far lower environmental footprint. High-pressure water mist is the non-chemical alternative. Sprinklers belong in office buildings and the kind of occupied container builds we fit out as workspaces, not in a sealed box holding server gear, batteries, and copper. The standard for IT fire suppression is a clean-agent gas system that smothers a fire without conducting electricity, leaving residue, or harming the people in the room. The two agents Ontario integrators specify in 2026 are FK-5-1-12 (sold as 3M Novec 1230, also as SF-1230 and similar) and the older HFC-227ea (sold as FM-200). They are not interchangeable from a procurement standpoint.
FM-200 vs FK-5-1-12, in plain terms
FM-200 (HFC-227ea) is the legacy clean agent. It has been the data-centre default since the 1990s. It is effective, it discharges in under 10 seconds, and it is rated under NFPA 2001 Standard for Clean Agent Fire Extinguishing Systems. The problem is environmental: FM-200 has a Global Warming Potential of around 3,220 with an atmospheric lifetime measured in decades. It is being phased out under the Kigali Amendment to the Montreal Protocol. New installations are not being approved in most jurisdictions, and Canadian integrators have moved their default to FK-5-1-12 over the last few years.
FK-5-1-12 (Novec 1230) is the replacement. Same NFPA 2001 listing, same 10-second discharge, same safe-for-occupied-space rating, electrically non-conductive, no residue. The key difference is the environmental profile: GWP under 1, atmospheric lifetime under 5 days. Storage is liquid in cylinders, discharge is gas. The agent works by removing heat from the flame rather than displacing oxygen, which is what keeps it safe for people in the room. Most Ontario integrators are specifying FK-5-1-12 on new container IT shelters because it future-proofs the build against the FM-200 phase-out.
High-pressure water mist shows up on some industrial container builds where the operator wants a non-chemical option. The droplets are small enough to evaporate on hot surfaces (cooling the fire and displacing oxygen at the same time) but not so much water that the IT gear gets soaked. It is heavier and more complex than a clean agent, and it requires a stored water supply, which most container builds do not want. Used selectively.
Whatever agent the integrator specifies, the system has to interlock with the HVAC. On discharge, the cooling units shut down, the dampers close, and the room seals so the agent concentration holds for at least 10 minutes (the NFPA 2001 hold time). If the HVAC keeps running, the agent disperses through the ductwork and the fire reignites. Every Ontario integrator who has worked on container IT shelters knows this. Verify on the shop drawings.
How should fibre and cabling enter the container?
Fibre should enter a container server room through one gasketed, watertight cable gland on the end wall, with fibre and copper run in separated overhead trays back to patch panels. Cable management is what separates a container server room that ages gracefully from one that becomes a rat king of patch cords inside three years. The build standard is ANSI/TIA-942-C, which calls for separate pathways for fibre and copper, overhead trays for power, and structured cabling that terminates on patch panels rather than running point-to-point between gear.
Cable management essentials for a container IT shelter
- Fibre entry: A dedicated, gasketed cable gland on the end wall, sized for the fibre count (typically 24 to 144 strands single-mode plus a copper service drop). The gland is the single most important detail on the container shell. Done right, it is watertight, EMI-shielded, and inspectable. Done wrong, it leaks water down the inside wall onto the cable trays.
- Overhead copper trays: Ladder rack or wire-basket tray mounted above the racks, fibre and copper in separated channels. TIA-942-C calls for this separation to prevent cross-talk and physical damage to the smaller-diameter fibre. Trays should be grounded to the container shell.
- Hot-aisle/cold-aisle alignment: Power cables run under the raised floor or in dedicated overhead channels on the hot-aisle side. Data cables run on the cold-aisle side. Never the same tray.
- Structured cabling backbone: A minimum of two optical fibres per pathway per TIA-942-C, terminated on patch panels. Single-mode OS2 for any backbone over 100 metres, OM4 multi-mode for shorter runs.
- Cable labels: Every termination labelled at both ends with a permanent printed label, not a Sharpie scribble. The integrator who builds the room is not the integrator who will troubleshoot it at 2 a.m. in 2032.
The fibre entry deserves a second mention. Container modifiers who do not specialise in IT shelters cut a 4-inch hole, run the cable through, and caulk around it. That works for a month. Then the temperature differential between the heated interior and the Ontario winter outside drives condensation, the caulk shrinks, and water tracks in along the cable jacket. The right detail is a manufactured cable gland (EMT-style or split-body, depending on whether the cable was pre-terminated) with a compression seal rated for the cable diameter, foamed into the bulkhead with closed-cell sealant, and inspected after the first thermal cycle. Pay for it once. It lasts the life of the container.
How do you secure a container server room?
You secure a container server room with card or biometric access on a reinforced man-door, interior and exterior cameras, an intrusion alarm, and grounded ESD flooring to stop static damage. A container server room sitting in a yard is a target. Treat it like one.
Security build essentials
- Access control: Card reader or biometric on the man-door, integrated with the operator’s existing physical security system. Mantrap configuration (two doors in sequence) on higher-security builds where the buyer has compliance obligations.
- Cameras: Minimum of one interior PTZ covering the racks and one exterior fixed covering the door. Onboard NVR or stream to the operator’s existing video management system over the fibre backbone.
- Door: Reinforced steel personnel door with a high-security lock, latch protector, and tamper-detection contact. The container’s original cargo doors are welded shut or sealed for service access only.
- Intrusion alarm: Glass-break sensors (if any windows are cut, which most server-room builds avoid), door contacts, motion sensors inside, all reporting to a monitored panel.
- ESD flooring: Vinyl ESD tile or conductive epoxy over the wood-and-vapour-barrier base, grounded to the container shell. Static discharge is a real failure mode in low-humidity winter operation. The flooring carries it to ground before it reaches the gear.
- Environmental monitoring: Temperature, humidity, water-on-floor sensors at every drain pan, smoke detection at the high-level cross-zone, all reporting to the building automation or DCIM system.
The ESD flooring is the detail buyers under-spec. Ontario winters drop the relative humidity inside a heated steel box to under 15 percent without active humidification, which is well below the 30 percent floor that ASHRAE recommends. Below 15 percent, static discharges in the kilovolt range happen every time a service tech walks across the floor. Conductive flooring solves it. Skipping it means a slow trickle of motherboard failures every February that nobody traces back to the floor.
Who buys container server rooms in Ontario?
Container server rooms in Ontario are bought mostly by school boards, municipal water and wastewater utilities, remote industrial and pipeline operators, and hospitals needing a separated comms backup. These four buyer profiles share almost nothing else in common. The container is the connecting thread.
School board IT closet / head-end
An Ontario school board’s network head-end traditionally lived in a basement room of the board office. The 1970s building has reached the end of its life and the board is moving to a new site in three years. A 20ft container, fitted out as a 4-rack IT shelter with N+1 cooling and a 20 kW UPS, sits beside the new modular school construction trailer and serves as the live network head-end during the build. When the new building opens, the container either moves into the building’s mechanical yard as the permanent IT shelter, or gets repurposed as a satellite IT closet at another site. The capital cost lives on the asset register for 20 years.
Municipal SCADA control room
A small Ontario municipality runs its drinking-water plant, lift stations, and wastewater treatment on SCADA. The control room used to be a closet beside the plant operator’s desk. New cybersecurity requirements (segmented OT network, hardened access, off-site replication) make that closet inadequate. A 20ft high cube container at the back of the plant yard becomes the new SCADA control room: 4 racks, dedicated UPS with 4-hour battery runtime, FK-5-1-12 clean agent, fibre backbone to the plant’s redundant fibre rings, biometric access, and full environmental monitoring tied to the existing operator workstation. The build cost lands below the engineering quote for retrofitting the original closet to the same compliance standard.
Remote oil-and-gas pumping station IT shelter
A pipeline operator runs a pumping station in northwestern Ontario, 80 kilometres from the nearest grid power upgrade. The station needs local compute for the leak detection and pressure modelling, plus a satellite uplink for the SCADA stream back to the operations centre in Calgary. A 40ft high cube container, insulated for minus-45-degree operation, with redundant solar-plus-genset power, two rear-door heat-exchanger cooled racks, and a Starlink Business uplink mounted on the roof, runs unmanned for 11 months a year with a single annual maintenance visit. Cargo-worthy steel because the operator amortises the asset over 20 years and the closest service vehicle is six hours away.
Hospital emergency communications backup
A regional hospital’s primary IT room sits in the building basement. A 2022 backflow event came within 30 centimetres of flooding the room. The board’s risk committee mandated a physically separated comms backup. A 20ft container on the loading dock holds the emergency communications gear, the secondary phone system, the radio repeater for the EMS link, and a 30-minute UPS that bridges to the hospital generator. Clean agent fire suppression, fibre tunnel back to the main building, biometric access for IT and facilities staff only. When the next basement event happens, the comms stay up.
Paul LeBlanc, Owner: “Industrial customers ask for cargo-worthy steel because they need the structure to hold modifications for 20 years of service life, not 5. A school board buys this once. A municipality buys it once. They are not coming back to replace the steel in eight years because someone sold them a tired container. The fit-out is the data centre. The steel has to last.”
Which container grade lasts a 20-year build?
For a 20-year IT shelter, the grade conversation comes down to two choices: a one-trip (new) container or a Cargo Worthy used unit. The grading conversation is where the cheap-container market trips up first-time buyers. There are four grades, and for an IT shelter built to last 20 years, three of them are wrong.
| Grade | Condition | Service life as IT shelter | Verdict |
|---|---|---|---|
| One-Trip / New Build | Single ocean crossing, factory paint, minor wear | 20 to 25 years | Best choice for client-visible builds and Tier III ambitions |
| Cargo Worthy (CW) | Re-certified for shipping, structural frame and floor inspected, surface rust | 15 to 20 years | Best value for a serious industrial IT shelter, with a fresh coat of paint |
| Wind & Watertight (WWT) | Doors close and seal, no light leaks, more cosmetic wear | 8 to 12 years | Workable for a temporary build, not a 20-year asset |
| As-Is | Older units with floor, frame, or door issues | Not recommended | Skip for IT use |
The buyer-side decision usually lands between One-Trip and Cargo Worthy. One-trip costs more because it is the premium tier, but you get a clean steel shell with original factory undercoat, square corners, original door seals, and a CSC plate valid for the next 5 years. For a client-visible or Tier III build, those factory-clean steel shells we keep at the Brantford yard are the safer starting point. Cargo Worthy is the operational sweet spot: structurally sound for the 20-year build, and after the integrator’s primer-and-paint pass it visually reads as good as new. Our walkthrough on inspecting a used unit before you pay covers the full grade comparison if a buyer wants to dig in.
What does NOT belong on a 20-year IT build: WWT units sourced from auction yards, As-Is units sold cheap on Facebook, or any container without a verifiable inspection record. The IT fit-out costs more than the steel. The small premium to start with the right shell pays back many times over when the integrator does not have to chase a rust hole through the spray-foam in year nine.
How is a container IT shelter delivered and sited?
A container IT shelter is delivered on a tilt-deck or roll-off truck and set on a level gravel or concrete pad the customer prepares in advance. Van Blanc delivers across Ontario in 1-3 days from our 4 Brantford yards. The container modifies in our yard or at the integrator’s facility, then ships to the customer site on a tilt-deck or roll-off truck. Site prep is the customer’s responsibility but the requirements are simple:
Site prep for an IT shelter delivery
- Pad: Level compacted gravel minimum 6 inches deep, or 4 reinforced concrete pads at the corner casting positions. Crushed limestone screening (granular A) compacted to 95 percent works for most sites. The container should sit on the pads, not on grade, to keep the floor frame dry.
- Drainage: Pad sloped 1 to 2 percent away from the door. Roof gutters or a drip edge if the container is shaded by anything that drops needles or leaves.
- Truck access: A tilt-deck truck needs 20 metres of straight approach with at least 4 metres of overhead clearance. A 40ft delivery needs more room than a 20ft. We send a delivery brief to every customer with the access requirements before the truck books.
- Utility connections: Power, fibre, and any chilled water loops trenched to within 3 metres of the container before delivery, in conduit, ready to terminate.
- Lifting access: If condensers or the cooling units are roof-mounted, the site needs room for a small crane on delivery day. Flag it in your quote so we plan the lift and the roof penetrations before the box leaves the yard, not on site.
Van Blanc delivers to every region across Ontario in 1-3 days from our 4 Brantford yards. Northern Ontario routes (Sudbury, Timmins, Thunder Bay) need 5 to 10 days for premium freight quoted per route. Every quote comes with a real lead time, not a hopeful one. Buyers from across Ontario regularly drive to our Brantford yard at 90 Morton Avenue East to walk a container before they order. Worth the drive for unbeatable quality, family customer service with 30 years of experience.
What drives the price of a container server room?
The price of a container server room is driven by the fit-out, not the steel. The steel shell is a small slice of the total. The build cost rides on the IT load, the redundancy spec, the cooling architecture, the UPS and battery sizing, the fire-suppression agent, and how much of the work the buyer’s own electrician and IT integrator handle in-house. A 40ft high cube built out for a serious industrial hall (CW steel, spray-foam insulation, two redundant in-row CRACs, a modular UPS with lithium runtime, clean-agent fire suppression, structured cabling, access control, cameras, ESD floor, and environmental monitoring) costs many times a 20ft, 4-rack SCADA or school-board shelter, because almost every one of those line items scales with the rack count.
The Facebook trap, applied to IT shelters
Many people call us saying they can get a cheaper bin on Facebook. Two weeks later they call back saying they got scammed. The dynamic is worse on IT-shelter builds. A buyer who saves on a Facebook 40ft, then pours a six-figure IT fit-out into a container with hidden floor rot, has built the whole thing on top of the rust. Six years in, the floor sags, the spray-foam separates from the steel, condensation tracks down the inside wall, and the integrator has to lift the whole rack frame to repair a hole that nobody could see at purchase. Pay the small premium for the verified container. The math is not close.
Because the build cost swings so widely with the spec, a posted number would be a fiction. Every project varies by site, by IT load, by redundancy spec, and by how much of the work the buyer’s own electrician and IT integrator does in-house. Van Blanc supplies the steel and coordinates the modification work with our shop and partner integrators. Every quote breaks out the steel, the modifications, and the IT fit-out as separate line items so the buyer can see exactly what they are paying for. Tell us the size and your postal code and we will send back an honest, all-in number, usually the same day.
Frequently Asked Questions
Can you really run a working server room in a shipping container?
Yes. Containerised data centres have been a recognised product category since Sun Microsystems shipped the Project Blackbox in 2006. Google, Microsoft, AWS, and major modular vendors (Stulz, Schneider, Rittal, Dell) all build container-based data halls. The ANSI/TIA-942-C standard explicitly accommodates outdoor modular containers. The fit-out is what determines whether the room runs reliably, not the steel shell.
How many 19-inch racks fit in a 20ft or 40ft container?
A 20ft container holds 4 racks in a single row with front-service access. A 20ft high cube holds 4 to 6 racks with room for an in-row CRAC. A 40ft holds 8 to 10 racks in a hot-cold aisle layout. A 40ft high cube holds 10 to 12 racks. The usable count drops if the build uses wider IT cabinets or in-row precision cooling between every two racks.
What is the difference between FM-200 and FK-5-1-12 (Novec 1230)?
FM-200 (HFC-227ea) was the data-centre clean-agent standard since the 1990s. It works, but it has a Global Warming Potential around 3,220 and is being phased out under the Kigali Amendment. FK-5-1-12 (sold as 3M Novec 1230) is the replacement: same NFPA 2001 listing, same 10-second discharge, GWP under 1, atmospheric lifetime under 5 days. Ontario integrators default to FK-5-1-12 on new builds.
How much cooling does a container server room need per rack?
Plan for 3 to 5 kW of cooling per rack for typical mixed IT loads. Compute-dense racks land at 10 to 30 kW. AI and GPU workloads run 30 to 50 kW per rack and need direct liquid cooling. Size the room cooling at the IT load plus N+1 redundancy, so one cooling unit can fail and the room still holds the ASHRAE TC 9.9 recommended inlet band of 20 to 25 degrees Celsius.
Will a container server room work in Canadian winters?
Yes, with the right build. Spray-foam insulation, sealed vapour barrier, head-pressure controls on the condensers, crankcase heaters on the compressors, and refrigerant charge tuned for cold-weather operation. The bigger winter concern is internal humidity dropping below 15 percent, which makes static discharge a real failure risk. ESD flooring and active humidification handle it.
What container grade should I buy for a 20-year IT shelter?
One-Trip (essentially new) for client-visible or Tier III builds, Cargo Worthy (CW) for serious industrial IT shelters where a primer-and-paint pass restores the visual. Skip Wind & Watertight (WWT) and As-Is for any 20-year build. Paul’s rule: the fit-out costs more than the steel, so start with steel that will outlast the fit-out.
How fast can Van Blanc deliver a container to my site?
Most Ontario regions get a container within 1-3 days from our 4 Brantford yards. Northern Ontario routes (Sudbury, Timmins, Thunder Bay, Sault Ste. Marie) run 5 to 10 days for premium freight quoted per route. The IT fit-out adds 8 to 16 weeks depending on the build complexity. We coordinate the steel delivery with the integrator so the box arrives at the modification shop on schedule.
