We engineered our Next Gen R-Series air-cooled condensing units to provide a winning combination of high-quality, increased flexibility and efficiency for lower long-term operating costs. A key feature is the integral sub cooling circuit that allows saturated liquid to flow from the receiver to the condenser where refrigerant is subcooled by ambient air-providing an average of 3 to 5 deg F of sub cooling for higher efficiency and excellent operating stability. The versatile units are designed to utilize R404A or other low global warming (GWP) refrigerants R407A, R407C and R448A/R449A and include a host of standard features and optional components.
