Quick answer
Imperial Brown builds custom walk-in coolers and freezers from four U.S. factories, including Gresham, Oregon and Tucson, Arizona, which makes it common on the West Coast. Beyond restaurants and grocery, it serves hospitals, labs, pharmaceutical storage and archives. Parts are sold through its partner site, Walk-In Parts Express.
About Imperial Brown
Imperial Brown's site describes custom-built walk-in coolers and freezers for foodservice (restaurants, schools, hotels, hospitals), grocery and convenience stores, and special projects such as labs, grow rooms, art and document archives, and biomedical and pharmaceutical storage. It lists four factories, in Gresham, Oregon; Salisbury, North Carolina; Prague, Oklahoma; and Tucson, Arizona. The company says it is 100% employee-owned and lists alliances with companies including Chase Doors, BASF and Heat Transfer Products Group (HTPG).
Specialty boxes need specialty service
| Application | What changes |
|---|---|
| Hospital and lab | Tight temperature bands, alarms, documentation, sometimes redundant systems |
| Pharmaceutical storage | Temperature mapping and monitoring; product cannot tolerate swings |
| Grow rooms and floral | High humidity and large moisture loads on the evaporator |
| Archives | Stable temperature and humidity; low airflow on artifacts |
| Foodservice and grocery | Door traffic, defrost and gasket wear |
For lab and healthcare boxes, see hospital and lab walk-ins.
Refrigeration on Imperial Brown boxes
Imperial Brown lists an alliance with Heat Transfer Products Group, whose brands include Russell. Many Imperial Brown boxes run Russell or other HTPG equipment, but custom boxes may carry any system. Check the condensing unit and evaporator data plates. See Russell refrigeration.
Common service calls
- Controller and alarm faults on specialty boxes.
- Door hardware on custom door sizes; Chase Doors parts on some installations.
- Evaporator icing in high-humidity boxes.
- Condensing units on hot Southwest-style rooftops.
- Panel joint sealing on boxes that have been reconfigured.
Parts and identification
Imperial Brown sells doors and parts through Walk-In Parts Express. Give the box serial number from the data plate; custom boxes often have non-standard door sizes, so measurements help. We service this brand; we work on it independently, and manufacturer warranty claims go through the manufacturer's own process.
Repair or replace
Custom panels are expensive to replace and often last decades. Replace refrigeration or individual panels before considering a new box. See repair or replace.
Custom boxes: what makes repairs different
Custom walk-ins are built to fit the room, so doors, panels and corners may not match any standard size. That affects repairs in three ways. Door parts must be measured, not just looked up. Replacement panels may need to be made to order, so lead times are longer. And the refrigeration may have been chosen for a specific load that has since changed. Keep the original order paperwork if you have it; it lists sizes and options that speed up parts orders.
Imperial Brown owner checks
- Photograph the box data plate and the refrigeration plates.
- Measure any damaged door: width, height and swing.
- Check the temperature with a separate thermometer.
- Note any alarm codes and when they started.
- For lab or pharmacy boxes, start your facility's excursion protocol.
Bay Area note
Imperial Brown's Gresham, Oregon and Tucson, Arizona factories put it close to the West Coast, so its boxes are common in Bay Area hospitals, universities, labs and grocery. Many are custom sizes fitted into older buildings, which makes careful measuring on the first visit worth the time.
Specialty project checks
- Confirm the setpoint and allowed range for the product stored.
- Check alarm contacts and test the notification.
- Check humidity where it matters (grow rooms, archives).
- Review service records for repeat faults.
Doors on custom boxes
Imperial Brown lists Chase Doors among its alliances, and custom boxes often carry oversized or special doors: wide cart doors, sliding doors on large rooms, or doors with view windows. These have their own hinges, closers and gaskets. Measure the opening, note the door maker's label if there is one, and photograph the hardware. Heavy custom doors also need their closers and hinges checked more often, because sagging on a wide door opens a big gap fast.
If a custom door is damaged beyond repair, a replacement can be made to the same size, but expect a longer lead time than for a standard door.
When to call a technician
For lab, healthcare or pharmaceutical boxes, call at the first alarm; product in those boxes is usually worth far more than the repair.
Open 7 days, 8 AM to 5 PM, with emergency service until 9 PM. CA Lic. #776244.
