Reach-in chilling equipment comes in one-, two- or three-door/compartment configurations, as well as wide-body and narrow-body models.  Smaller, under counter reach-ins can provide convenient added storage space for products needed at a display-preparation or service point.  Reach-ins can be configured as combination refrigerator-freezers with separate temperature readouts.  Pass-through reach-ins allows access from both sides. Glass-fronted reach-ins allows easy identification of contents and is suitable for “grab ‘n go” and merchandising displays.

Top-end reach-in units are typically manufactured of aluminum and stainless steel in a variety of combinations with all-stainless construction representing units’ highest cost factor.  Less-expensive reach-ins may use aluminum to form their sides and interiors or utilize a plastic coating for interiors and door liners.  Reach-ins generally utilizes 2” to 3” of rigid or foamed-in-place polyurethane insulation to help maintain interior temperatures.  Reach-in refrigerators are manufactured to maintain an interior temperature of 40 degrees or below, while reach-in freezers should maintain an interior temperature around zero.  Glass-door display freezers hold temperatures as low as -15 to -20, and come with interior lighting, mirrored interior panels and exterior message displays.  Depending on size, reach-in units may require more than one compressor.  While a one-door unit typically requires a single ½ hp compressor, a two-door unit will need a ¾ hp compressor and a three-door unit requires a 1-hp compressor.  Four-door units rely on two ¾ hp compressors to ensure even cooling and temperature maintenance.  Remote compressors are available that save space and reduce energy loads.

Almost any reach-in can be fitted with either one full-door or two-half doors.  While they take up a bit of storage space, half-door configurations help maintain internal cabinet temperatures and reduce energy costs by allowing less cold air to escape when opened frequently.  Many operators look for sliding doors or doors with a 90 stay open feature and adjustable stops in tight spaces.  Sliding doors may be specified as a space-saving measure.  Reach-ins are typically equipped with four adjustable heavy-duty vinyl-coated wire shelves per door.
