HCA Retrofit Heat Pump

The HCA Series are a direct replacement for McQuay HCA units. This provides contractors with a simple drop-in replacement unit with the added feature of modern microprocessor control capabilities.

Specifications

  • Quiet, high efficiency R410A compressors are available for all units. Units up to 2 Ton use a rotary compressor. Units above 2 Tons utilize scroll compressors. All compressors come with overload protection.

  • An auto shut off valve is available to disable water flow through the unit when there is no call for the compressor. This provides an opportunity to save system pump energy when the compressor unit is off.

  • Water coil freeze protection is offered on all units through direct refrigeration control. A DDC control board monitors and ensures units are turned off before any damage to the unit occurs. Internal logic of the board also minimizes nuisance trip outs.
