Cruisair R-type marine HVAC condensing units are seawater-cooled, reverse-cycle heat pumps for cooling and heating in marine applications.

These condensing units can be installed with up to 2 cooling units, where the total capacity is equal to the condensing unit capacity. Units can be installed in the vessel's engine room or other mechanical space, and are not affected by moisture, normal vibration, or ambient temperatures up to 140 degrees F (60 degrees C). No ventilation is required.

Three different models are available to accommodate different types of controls. "R" uses the 3-knob rotary switch assembly. "RX" uses the SMX II digital control. "RN" uses the SMX Net digital control.
