Market / Pharmaceutical
Pharmaceutical cold storage is judged on excursions, not averages. A food walk-in that drifts a few degrees wastes energy; a pharma cold room that drifts quarantines product and triggers a deviation report. WFE builds medical-grade cold rooms and freezers for pharmaceutical distributors and cold chain operators across Ontario, with the same in-house crew from layout through commissioning, and the build records your quality team needs to qualify the room.
Fig. 01 · What you actually buy
A standard walk-in keeps food cold. A pharmaceutical cold room has to hold a tight temperature band, run cooler and freezer zones, stay airtight, and document everything for your quality file.
Here is what each one means for your licence and your product.
Refrigerated drug product lives at 2-8°C, and an excursion is not an efficiency problem: it is quarantined stock and a deviation report. We size the envelope, the refrigeration, and the airflow so the band holds through door-cycles and summer ambient, with capacity margin instead of a thermostat running flat out.
WFE built a 10,000 sq ft medical-grade cooler and freezer envelope at Pacer Air Freight in the Mississauga air-freight corridor: every panel measured and cut to fit, tight seams, finished as one airtight envelope. Same build system, sized to your volume.
Panel-to-panel seams, floor-to-wall transitions, and door perimeters are each sealed against ambient air exchange. A gap that reads as efficiency loss in a food walk-in reads as temperature drift on a pharma mapping study, so every interface is finished airtight before the refrigeration plant ever starts.
The same in-house WFE crew frames, seals, and commissions the room, then hands over the equipment spec sheets, commissioning records, as-built drawings, and temperature verification logs your quality file needs. No subcontractor chain between the build and the paperwork.

Fig. 04 · Recent build
WFE built a 10,000 sq ft medical-grade cooler and freezer envelope at Pacer Air Freight in Mississauga, inside an operating air-freight facility. Every panel was measured and cut for tight seams and consistent insulation, then sealed into one airtight envelope by the in-house crew.

Deep Dive
Expand any section for the full detail on Health Canada storage requirements, why food-grade contractors get it wrong, the three temperature bands, the airtight envelope, monitoring, and industrial scale.
Health Canada's guidance on environmental control of drugs during storage and transportation (GUI-0069) requires wholesalers and distributors to store drug product under the conditions on the label, monitor those conditions, and document control. The standard bands: 2-8°C for refrigerated product, 15-25°C controlled room temperature, and -25 to -15°C for frozen product. WFE builds the room and supplies the equipment spec sheets, commissioning records, and temperature verification logs that feed your Health Canada GMP and GDP quality file.
Most quotes you will get for a pharma cold room are a food-grade walk-in cooler with a tighter thermostat setting. Food refrigeration is engineered around a tolerant product: a few degrees of drift, a leaky seam, an unmonitored door all cost efficiency, nothing more. Pharmaceutical storage inverts that. The envelope has to be airtight, the airflow uniform across the racked volume, and the temperature record continuous, because the pass-fail test is a mapping study, not a thermostat readout.
Most pharmaceutical distributors hold more than one band: 2-8°C refrigerated, 15-25°C controlled room temperature, and -25 to -15°C frozen. Each wants its own zone with its own set-point, alarm limits, and door discipline. We build multi-zone envelopes with zoned control so one build covers the full profile, with independent monitoring per zone.
Airtight means the structural walls, the panel-to-panel seams, the floor-to-wall transitions, and the door perimeters all hold against ambient air exchange. Each interface gets the right seal type: panel joints with pharma-rated sealant, floor transitions sealed against the slab, and doors with perimeter seals that hold under repeated door-cycles. The result is an envelope the refrigeration plant can hold to spec without fighting ambient infiltration. This is the build standard WFE ran on the Pacer Air Freight medical-grade build.
Your quality team runs the qualification; the room has to give them something to qualify. We install panel-mounted temperature data loggers with exportable records, door-contact alarm switches, and hand over commissioning records and as-built drawings at handover. When your QA lead runs the temperature mapping study, the build documentation behind it is already in the binder.
Pharmaceutical cold storage scales from small qualification rooms of a few hundred square feet up to full distribution envelopes. The largest medical-grade build WFE has run is the 10,000 sq ft cooler-and-freezer envelope at Pacer Air Freight in Mississauga, built inside an operating air-freight facility with shared mechanical systems and a continuous airtight envelope.
