Walk in Rooms for Commercial Cold Storage and Freezers

A walk-in room is an insulated, temperature-controlled enclosure large enough for a person to enter and move around inside. In commercial settings, walk-in rooms are used to store perishable goods at precise cooler or freezer temperatures, consisting of insulated panel walls, a ceiling, a floor, and a prehung door system engineered to maintain consistent interior temperatures.

A walk-in cold room is a refrigerated walk-in enclosure maintained at above-freezing cooler temperatures, typically between 34°F and 40°F. Unlike a walk-in freezer, it is designed for short-term perishable storage such as produce, dairy, beverages, and prepared foods, and is commonly used in restaurants, grocery stores, hotels, hospitals, and food distribution facilities.

ELT Custom Coolers stocks 65 walk-in cooler replacement doors and 51 walk-in freezer replacement doors in standard widths from 30" to 60" and heights from 76" to 84". Sliding door systems are available up to 12'x12'. Custom sizes for non-standard openings are also manufactured in-house at no upcharge, with same-business-day quotes available.

Swing doors are the standard choice for most walk-in coolers and freezers and install in about one hour, making them ideal for typical foot-traffic access. Sliding doors are better suited for high-traffic, wide-opening applications where forklifts, pallet jacks, or carts must pass through. ELT offers prehung sliding cooler doors up to 12'x12' and sliding freezer doors up to 96"x120", with heated jamb options available for sub-zero freezer environments.

A heated frame or heated jamb uses an electric heat wire embedded in the door frame to prevent frost, ice buildup, and door-stick at the freezer opening. This is especially important in high-cycle freezer doorways and low-temperature applications ranging from -20°F to -40°F. ELT offers heated frame options across multiple freezer door configurations, including both swing and sliding doors.

Yes. ELT Custom Coolers' prehung replacement doors are designed as drop-in replacements that install directly over existing wall panels in approximately one hour, with no panel replacement required. Both plug frame and standard jamb frame options are available to fit original openings correctly, minimizing cold-storage downtime during the door-swap.

ELT Custom Coolers' walk-in cooler and freezer products are NSF Approved, UL Certified, and DOE 2017 Compliant, ensuring they meet recognized standards for food safety, electrical/safety listing, and commercial refrigeration energy efficiency.
