Product Description

The same basic machine as the CX65 / CX65X, the CX75X is "turbo-charged" for higher capacity.

The "X" in the model number means the units have an upgraded enclosure and a stainless steel pump.

The CX65 and & CX75 model family use a new version of the same award-winning USA patented technology as CX34, CX35, and CX50.

Both CX75 and CX75X include DYNAMIC HUMIDITY CONTROL (DHC) factory Installed on all units. *Requires indoor RH sensor.

Beats all other of air to water heat pumps in its size range for average annual heating & cooling efficiency

Stainless Steel Pump

No requirement for Oxygen-Barrier PEX. The CX65X comes with a long-lasting stainless steel pump, all wet-contact components are non-ferrous
