Industrial Refrigeration Equipment: An Overview

A standard frame walk-in freezer door works for most low-temperature applications, while a heated frame (heated jamb) option prevents frost buildup, ice-up, sweating, and door-stick that commonly occurs in freezer environments. Heated frame configurations are especially recommended for high-cycle doorways or sub-zero duty applications below -10°F.

Yes. Walk-in freezer sliding doors are available prehung with a jamb sandwich frame and header in sizes up to 96"x120", specifically designed to accommodate forklift, pallet jack, and cart pass-through. The wider opening footprint makes them ideal for food-processing plants, distribution warehouses, and large-format grocery backrooms.

Yes. ELT Custom Coolers offers equipment financing through MyCloudFunding, a third-party financing partner. This allows businesses to lease or purchase walk-in doors, sliding door systems, strip curtain sets, and complete walk-in box units with flexible payment options rather than a single upfront cost.

A PVC strip curtain is a secondary doorway barrier made of overlapping plastic strips installed in cooler and freezer doorways. It maintains temperature separation when the main door is open, reducing cold air loss and compressor run-time by 20–40% on high-cycle doorways. It also cuts ice buildup on door frames and supports food-safety temperature compliance.

Yes. ELT Custom Coolers manufactures custom-sized walk-in cooler and freezer doors in-house for non-standard openings, oversized walk-in boxes, and retrofit projects. Both swing and sliding door configurations are available in custom dimensions beyond the standard stocked sizes, with options for standard, plug, and heated frame types.

The 8'x8'x8' walk-in box package includes the factory-built insulated panel structure and a prehung walk-in cooler or freezer door. The refrigeration unit is sold separately. This compact turnkey box is configurable for cooler or freezer temperature duty, making it ideal for restaurants, ghost kitchens, floral shops, c-stores, and cannabis dispensaries.
