Unit Coolers

Product Overview

Refrigeration Systems (RSI) Unit Coolers are designed for product pull down and storage in warehouse cooler and freezer applications in the commercial and industrial produce refrigeration markets. These Unit Coolers are constructed of a heavy-gauge, smooth finish aluminum cabinet with a copper tube, aluminum plate fin coil, and permanently lubricated ball bearing fan motors with inherent thermal protection.

Many RSI Unit Coolers also include an insulated drain pan and an adjustable defrost termination/fan delay. These draw-through Unit Coolers are ceiling mounted and are available configured as air defrost, electric defrost or hot gas defrost.
