The Unichiller RC is a reverse-cycle chiller that provides hot water for heating and cold water for cooling. According to the company, the unit has quieter operation despite a greater flow of air moving through the swept wing-shaped fans than conventional chillers provide. The Unichiller RC outside unit features a corrosion-resistant pump, tube-in-shell evaporator, and fully adjustable water temperature control. In addition, it includes a thermostatic expansion valve, high- and low-pressure limit switch, flow switch, hermetically sealed refrigerant system, and liquid line filter-drier. It is available in 3- and 5-ton capacities.
