Ultra-High Efficiency

Small Air Cooled Chiller Heat Pump (Reverse Cycle Chiller)

Advanced variable capacity DC Inverter Chiller with built-in variable speed pump - needs no buffer tank, no cooling tower, no water consumption - and it's perfect for ductless systems of up to 8 indoor units, solar integration, solar thermal, or hydronic floor heating. This small chiller is perfect for residential or small office use - it's two tons of energy efficient heating and cooling - and it's modular so you can easily create 2,4, or 6 ton systems.

AHRI-Certified IPLV EER 23

World-record setting performance!
Use it with the DYNAMIC HUMIDITY CONTROLLER to increase to NPLV EER 31

small air cooled residential chiller heat pump - ductless

Perfect as a residential chiller, the CX34 can be "stacked" to create 2,4,or 6 ton systems. The CX34 system can be configured as ductless heat pump chiller with hydronic fan coil units, or can be set up as a small central heat pump chiller system using hydronic air handler units available from various manufacturers. Or use it for floor heating, or any combination of these methods mentioned above.

What is a chiller? There are many misconceptions about chillers - to be clear, the Chiltrix system is an R410a air cooled system and does not consume any water, and does not need a cooling tower. It dehumidifies just like a normal air conditioner and does not add water to the air. It is a hydronic heating and cooling system which means that the outdoor unit connects to the indoor units via insulated hydronic lines (water lines) - this is what defines a "chiller". In the case of Chiltrix, the unit is a reverse-cycle chiller, meaning that it is a heat pump and can run in either cooling or heating mode as the case may be. All of the refrigeration components such as compressor, evaporator, condenser, expansion valves etc. are located in a self-contained outside unit. The outside unit connects to one or more indoor units by water lines.

*SEER 31. Note, there is no official SEER rating for chillers. However, to provide the same cooling for the same amount of total power usage, a central air conditioner system would need a SEER rating of up to 31 or above to exceed the performance of a CX34 ductless system.
