Manufactured beginning in 1994, the Rheem RALB is a discontinued, standard efficiency cooling unit. This 1.5- to 5-ton series is a member of Rheem’s Classic Series and offers up to 12.5 SEER. This series is available in seven different models ranging in cooling capacities from 17,000 to 56,500 BTU/H.
All models of the RALB are equipped with a Copeland scroll compressor, single-speed motor, copper tube/aluminum fin coils and drawn base pan for efficient, quiet operation. The interior components are protected by a powder-painted galvanized steel cabinet, while a wraparound louvered grill shields the coils from environmental hazards.
Accessible refrigerant connections, control box and a separate compressor box contribute to the easy installation and service of this unit, according to the manufacturer. In addition, the RALB is compatible with a full line of factory-installed accessories, including a compressor time delay control, high/low pressure control and crankcase heater.
