Cooling with your Product in mind
RSI unit coolers are designed for product pull down and storage in warehouse cooler and freezer applications for commercial and industrial refrigeration markets. They 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 units also include an insulated drain pan and an adjustable defrost termination/fan delay. These draw through units are ceiling mounted and are available configured as air defrost, electric defrost or hot gas defrost.
