Commercial Grocery Store Freezers and Applications

ELT Custom Coolers stocks 51 prehung walk-in freezer replacement doors in widths from 30" to 60" and heights from 76" to 84". Sliding freezer doors are available in 7 sizes from 47"x78" up to 96"x120". Custom sizes are also manufactured for non-standard grocery store backroom openings.

A heated frame (or heated jamb) runs a low-wattage heating element along the door frame to prevent frost and ice buildup at the seal. Grocery stores operating high-cycle freezer doorways — where warm, humid air enters frequently — need heated jamb doors to stop freeze-up, door-stick, and the energy loss caused by a compromised door seal.

A strip curtain such as the Kason 402 Easimount acts as a secondary thermal barrier across the freezer door opening. When the main door is open during restocking or high-traffic periods, the PVC strips reduce cold-air loss and warm-air infiltration. This can cut compressor run-time by 20–40%, reducing energy bills and ice buildup on the door frame.

Yes. ELT Custom Coolers offers prehung walk-in freezer sliding doors from 47"x78" up to 96"x120", all with a jamb sandwich frame and header pre-assembled for drop-in installation. Select configurations include a heated jamb option. Sliding doors provide the wide opening footprint required for pallet jack and cart pass-through in high-throughput grocery backrooms.

A standard frame mounts to the face of an existing walk-in panel opening, while a plug frame inserts directly into the panel opening for a flush, thermally efficient fit. Heated versions of both frame types are available. Choosing the right frame type depends on your existing walk-in box panel construction — ELT's team can advise based on your specific opening dimensions.
