Inverter Variable Speed Heat Pump Chiller - simply the most efficient chiller available!

The Chiltrix ultra-high efficiency air-to-water heat pump CX34 has been awarded the ENERGY STAR 2019 Emerging Technology Award.

49dB(a) Super Quiet Sound Levels - like a mini-split outdoor section

3-Tons Heating / 2-Tons Cooling (Stackable to create systems of 2 ,4, 6 Tons, etc)

IPLV(integrated part load value)= 26,150 BTU Cooling / 33,813 BTU Heating


Flexible Design Options:
High Velocity Air Handlers, Mini-split/Ductless, Central Ducted, or Integration w/ Floor Heat, Boiler or Solar Thermal

AHRI-Certified. Connect up to 8 indoor units.

The CX34 obtains it’s ultra high efficiency using existing technologies in a new way. For example, we use a DC Inverter compressor and a DC Inverter water pump (both are variable speed) controlled together with a DC inverter fan motor to achieve the best possible balance of water flow rate, compressor speed, and energy use (364 watts to 2360 watts at 230 volts). A special control algorithm looks at the temperature delta between the entering and exiting water temperatures of the chiller, and also compares the exiting water temperature to the system settings. The controller constantly adjusts the pump and compressor speeds independently of each other to maintain the needed capacity at the lowest possible power draw, usually avoiding the need for a buffer tank. There is not a more efficient air source heat pump chiller made anywhere by anyone.

The CX34 system capacity is fully dynamic and can operate between 25% and 100% of its rated capacity, as needed, and matches its actual capacity to the instantaneous heating or cooling load in real time. This means the system is always the right size for changing conditions and is never oversized and avoids the on/off cycling of traditional systems.

Every trick in the book and then some were used to create the Chiltrix heat pump chiller. This is the AHRI-Certified small heat pump unit of the future that is very easy to install and eliminates all lineset length issues. Cooling or heating is transported via simple water/glycol lines. The outdoor unit is completely self-contained. Just add power and connect the water lines. The indoor units are also very simple to install, just add power, connect the water lines, and connect a condensation drain line.  The CXI series DC-Inverter fan coil units are the quietest fan coil units on the market. 

Best of Breed Components:
Chiltrix didn't stop at creating the most efficient heat pump chiller on the market.  The components used to build the 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 an inverter variable speed compressor from Mitsubishi.  No corner has been cut when it comes to making sure that the parts and materials used to manufacture the CX34 are the best available. This 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. 5-year Mitsubishi Inverter compressor warranty and 2-years on all other parts.  Assembled in China.  All replacement parts are housed in the USA.

Anti-Corrosion technology is used on all outdoor units, protects against salt air in coastal environments.

COOLING: What makes an ultra-efficient air conditioner? . What really makes an air conditioner stand out is how it performs under part-load conditions, which is the strength of chiller systems in general and an area where the Chiltrix chillers beat the competition. The CX34 has an AHRI-Certified IPLV of EER 23, this means that the average rated efficiency in cooling mode is 675% (COP 6.75)

HEATING: The CX34 is well above average with up to 392% (COP 3.92) heating efficiency.  Provides heating down to -4°F.

OPTIONAL: Psychrologix™
Controller offers DHC (Dynamic Humidity Control) function to dynamically control humidity and operate the chiller well above its already high IPLV efficiency ratings at times when the indoor humidity allows.  Controller dynamically manages compressor speed, pump speed, fan speed, loop temperature, coil temperature and more. Includes many automated chiller control functions.

OPTIONAL: CXSE free cooling module. 
When outdoor temperatures drop below 38°F, the CX34 glycol-water loop is automatically extended through a special water-to-air heat exchanger to harvest outdoor cold ambient conditions to pre-cool the glycol-water loop so that the CX34 variable speed compressor can drop to a very slow speed and consume less power. This can save about 50% off of it's already low power consumption without lowering capacity.

At 28°F and below, the CX34 chiller with Free Cooling SE add-on will turn off the compressor entirely and still be able to maintain its rated cooling capacity using only the variable speed pump and fan motors. At this point, the CX34 achieves a COP of of >41 and EER of >141.

Enjoy the savings of 2 tons of cooling for less than 75 watts. The colder it gets, the less water flow rate is needed, allowing the VSD pump power draw to drop under 20 watts.

Depending on location, for some customers free cooling mode can be active up to 3 months per year during the daytime and up to 5 months per year at night. [click here for details]

If you have good quality water and are using glycol in your water loop, then you can use tap water to fill the system loop.  If you have poor quality water and/or aren't using glycol in the system, then you would need to use distilled water to fill the system.
