Types of Supermarket Coolers and Freezers

ELT Custom Coolers offers swing (manual) replacement doors prehung with frame, sliding doors prehung with jamb sandwich frame and header, and PVC strip curtain sets. Swing doors are ideal for standard back-of-house coolers and freezers, while sliding doors are suited for high-traffic or forklift-access openings. Strip curtains serve as secondary barriers on any doorway.

Walk-in cooler replacement swing doors are available in widths from 30" to 60" and heights from 78" to 130", with 65 standard SKUs in stock. Sliding cooler doors range from 36"x78" up to 12'x12'. Walk-in freezer swing doors cover widths 30"–60" and heights 76"–84". Custom sizes are manufactured in-house for non-standard openings.

A heated jamb or heated frame embeds electric resistance heating elements in the door frame to prevent frost buildup, ice-up, sweating, and door-stick — common problems in freezer environments. It maintains a clear, ice-free seal around the door opening, reducing maintenance calls and ensuring the door closes properly without manual defrosting or forced entry.

A standard frame mounts to the exterior face of the walk-in box opening, while a plug frame is designed to insert directly into the existing opening — the right choice for older walk-in boxes originally built for a plug-style door. ELT Custom Coolers offers both frame types across its swing door product line for coolers and freezers.

A strip curtain acts as a secondary barrier across the doorway, significantly reducing cold air loss during high-traffic door-open periods. The Kason 402 Easimount strip curtain can reduce compressor run-time by 20–40% on high-cycle doorways, limit ice buildup on freezer door frames, and support food-safety temperature compliance — all without impeding employee movement.

Yes. ELT Custom Coolers offers a complete 8'x8'x8' walk-in cooler or freezer box that includes the insulated panel structure and a prehung door. It is configurable for either cooler or freezer-temperature duty and is ideal for new build-outs, ghost kitchens, c-stores, floral shops, and other small-format commercial applications needing a turnkey cold storage solution.
