CX50 uses the same award-winning technology
as CX34. And, it has been optimized for heating performance while
still beating every air to water heat pump in the industry (except the
Chiltrix CX34) for cooling.



The CX50 obtains its ultra high efficiency using our award-winning technologies in a new, larger system optimized for increased heating performance while still delivering extreme cooling efficiency. The CX50 uses a Mitsubishi DC Inverter compressor, a DC Inverter water pump (both are variable speed) controlled together with a DC inverter variable speed fan to achieve the best possible balance of performance, optimized water flow rate, compressor speed, and energy use. The CX50 uses R32 for higher energy efficiency, with zero ozone depletion, and 67% lower global warming potential (GWP 675) than standard refrigerant R410a (GWP 2090). R32 allows higher capacity, uses less total refrigerant, and is less toxic than R410a with ATEL of 220,000 PPM. Dynamic Humidity Control (DHC) The Chiltrix Psychrologix ™ controller offers DHC (Dynamic Humidity Control) to maximize comfort and performance and allow the unit to operate well above its published ratings at times when humidity allows. The controller provides dynamic loop/coil temperature adjustment among other features. The CX50 system capacity is fully dynamic and can operate between 27% and 100% of its rated capacity, as needed. This means the system is always the right size for changing conditions and avoids the on/off cycling of traditional systems. Heating, Cooling, Domestic Hot Water Use any or all in the same application.
Radiant, Ductless Fan Coils, Ducted Use any or all in the same application.
Save More w/ DC Inverter Fan Motors All of the thin-line (5.1" thin) wall, floor and ceiling fan coil units use high efficiency and nearly silent DC Inverter fan motors, designed for 115v power. 220v 50 Hz standard FCUs are available for export customers.
Geothermal Performance There is no Energy Star program for air to water heat pumps. However, the Chiltrix air-cooled chiller exceeds the Energy Star EER requirements for geothermal water to water systems.
Solar Ready Perfect for solar PV operation with super low power draw and a 3 amp soft start that’s easy on inverters and batteries. Also integrates directly with solar thermal hydronic heating & solar water heating systems.
Radiant, Boiler & Hydronic Integration Can serve as low-cost primary heat when used with an existing boiler heating system. Perfect for radiant floor heating. Dramatically reduces heating costs for users of electric, propane or oil fired boiler systems.
Dynamic Heating Performance The CX34 provides heating down to outdoor temperatures as low as -17 °F. We publish data to -4F. And the optional V18 variable backup heater can be directly integrated for precise dynamic control and the highest efficiency ever achieved by an electric hydronic backup heater.
Best of Breed Components At Chiltrix we used every trick in the book and then some to deliver the highest energy efficiency possible. And we didn’t stop there. The components we use to build our chillers are sourced from the world’s top manufacturers and include heat exchangers from Sweden, German pumps, American valves, electronics from Japan, controls from USA, and a compressor from Mitsubishi.
No corner has been cut when it comes to making sure that the parts and materials used to manufacture the CX50 are the best available. Our chiller is designed for performance - to deliver the lowest kW usage per BTU of any chiller heat pump available, and to perform this task for a 20+ year service life.
Anti-Corrosion Technology to protect against salt air or air pollution is incorporated into all Chiltrix outdoor units. Includes special coil, hermetically sealed compressor and fan motor.
There is no other ATW heat pump like the CX50 available on the market at any price. Contact us to learn more about designing an air to water heat pump chiller system for your home, commercial location, or server room. We can also help you integrate our system with an existing system, retrofit replacement, integration with solar or to an existing boiler or hydronic heating system.
Flexible Indoor Options – Any Combo: You can use up to 12 or more ductless fan coil units of any type including wall mount, ceiling, floor standing, etc. with a single Chiltrix air to water heat pump chiller. You can also use (AHU) ducted fan coil air handlers for a central (forced air) heating & air conditioning system, use it with a radiant floor or radiant panels, or with concealed ceiling fan coils, mini-ducts, or use any combination of these. Domestic water heating may be added to any of the above.
