Walk In Cooler Units for Commercial Refrigeration

Costs vary widely by size and configuration. A complete 8x8x8 walk-in cooler box starts at $7,800 USD. Prehung replacement doors range from $1,250 to $5,500 depending on size and frame type. Larger sliding door systems can range from $2,800 to over $15,500. Equipment financing is available through MyCloudFunding and Affirm for flexible ownership options.

A walk-in cooler uses a refrigeration system — typically a compressor, condenser, and evaporator — to remove heat from the insulated box interior, maintaining temperatures between 35°F and 41°F. The insulated panels and a tightly sealed prehung door prevent heat transfer. Self-contained units like top-mount packages house all refrigeration components in one assembly for simplified installation.

ELT Custom Coolers stocks 65 prehung walk-in cooler replacement doors in widths from 30" to 60" and heights of 78", 80", 84", and 130". Sliding cooler doors are available in 18 sizes up to 12'x12'. Custom sizes are also manufactured at no upcharge for non-standard openings, with same-business-day quotes available.

A plug frame door fits inside the existing cooler wall opening without requiring a full jamb installation — ideal for retrofitting older walk-in coolers with an existing plug-style cutout. A jamb frame includes a full perimeter frame that mounts to the wall face. ELT offers both options across its swing door lineup to accommodate virtually any existing opening configuration.

Most prehung swing cooler doors install in approximately 1 hour by dropping in over existing wall panels — no panel replacement required. Sliding cooler doors with track, trolley, and header systems typically take 2–4 hours. ELT can also refer buyers to a nationwide network of commercial refrigeration contractors for professional installation.

A. Brown & Son. The prehung design installs over existing wall panels, minimizing downtime and eliminating the need for full box disassembly.
