Commercial Refrigerators for Grocery and Convenience Stores

Grocery store walk-in coolers and freezers use a refrigeration cycle: a compressor pressurizes refrigerant, which releases heat through a condenser coil and then absorbs heat inside the box through an evaporator coil, lowering the interior temperature. Insulated panels and well-sealed doors — including prehung replacement doors and strip curtains — are critical to maintaining temperature and minimizing compressor run-time.

ELT Custom Coolers offers prehung swing replacement doors in 65 standard sizes (30" to 60" wide, 78" to 130" tall) and sliding cooler doors from 36"x78" up to 12'x12'. Standard, plug frame, and heated frame options are available to fit virtually any grocery or convenience store walk-in opening.

A standard frame walk-in freezer door works well in most freezer applications, but in high-humidity or deep-freeze environments, moisture can cause frost and ice buildup around the door jamb. A heated frame or heated jamb door uses embedded heating elements to prevent frost, ice-up, sweating, and door-stick, which is essential for reliable operation in commercial grocery and c-store freezers.

Installing energy-efficient prehung replacement doors, adding PVC strip curtains like the Kason 402 Easimount, and upgrading to DOE 2017-compliant door hardware can reduce compressor run-time by 20–40% on high-cycle doorways. Proper door seals, cam-rise hinges, and hydraulic door closers also help maintain temperature consistency and lower utility bills.

Yes. ELT Custom Coolers manufactures custom-sized walk-in cooler and freezer doors for non-standard openings, oversized walk-in boxes, and retrofit projects. Custom doors are built in-house and available for both swing and sliding door configurations. Contact the team with your exact opening dimensions to receive a quote.

A complete walk-in cooler door replacement typically requires hinges (such as the Kason 1245 cam-rise hinge), a hydraulic door closer (such as the Kason 1094 SureClose), a handle (Kason 1229), an inside safety release handle (0481 Safety Glow), and optionally a strip curtain for high-traffic doorways. ELT Custom Coolers stocks all these components for one-stop sourcing.

All ELT Custom Coolers products meet UL, NSF, and DOE 2017 standards. UL certification confirms electrical and structural safety, NSF approval ensures the products meet food safety and sanitation requirements, and DOE 2017 compliance means the equipment meets federal energy efficiency standards — helping cut compressor run-time and utility costs while keeping your cold storage fully compliant with regulations.
