Roll-in Refrigerators: An Overview

Roll-in refrigerators keep food temperatures between 36 and 38 degrees F. 

A roll-in refrigerator, part of the reach-in category, is built on wheels for enhanced versatility in the kitchen. These units accommodate carts containing food pans.

Although these units can be identical in terms of size or bigger than a conventional refrigerators, roll-ins provide operators with a good amount of storage space and increased flexibility.

These units are generally classified by size, or specifically by internal cubic capacity, which determines how many pans can be held at one time. In terms of storage, roll-ins can accommodate carts from 54 inches high up to 85 inches high.

Roll-in refrigerators also are categorized by the number of doors that are on the front, one-, two- and three-door models are available.

High-end units are constructed of stainless steel both inside and out. Aluminum roll-ins are less expensive. Models with stainless steel exteriors and aluminum interiors also are available.

All reach-ins use a compressor, evaporator coil and evaporator fans for cooling. Metering devices, however, may differ. While some units have a capillary tube that carries refrigerant, others use an expansion valve flow device, which offers better temperature recovery in high-volume operations.

Roll-ins typically operate on 115 volts of electrical power, with the exception of three-door units, which may use either 208 or 230 volts. Depending on their size, these units require between a ½-hp and ¾-hp compressor.

Thermometer or electronic control systems are available.

As for the compressor, roll-in refrigerators are available in either self-contained or remote models.
