Supports up to 7 indoor units per system.

Five sizes of indoor units range from 2,600 BTU to 11,500 BTU for use in ductless or mini-split chiller configuration with no lineset limits. The CX30 also works with solar or hydronic floor heat, boilers, or central HVAC design. Stackable up to 10 units.

Ultra-Efficient R410a Reverse Cycle Chiller w/ DC Inverter Compressor, DC Inverter Pump & DC Inverter Fan Coils.

Ductless, Ducted/Central, or Hydronic Compatibility. Ductless Configuration Eliminates Duct Loss and Ductwork Installation Cost. Low Ambient Cooling & Heating to -14F.

Heating 2.5 Tons / Cooling 2 Tons & Stackable to 20 Tons. Sealed, Self-Contained Outdoor Unit. No Lineset Limits, Low Cost Installation.


We use a variable speed DC-Inverter compressor that reduces the CX30 heating or cooling output by reducing its speed at times when full capacity is not needed. As the compressor speed decreases, so does the compressor’s energy use. When measured on an annual basis, the average energy savings produced by the variable capacity compressor alone reflects up to 30-40 percent savings.

We also use a variable speed (VSD) pump for the hydronic loop circulation. When full water flow is not needed due to off-peak capacity requirements, the water pump slows down and uses less energy. The variable speed pump and variable speed compressor work in tandem with a microcontroller using a special algorithm to keep the compressor and pump both working at the optimum speed. This allows the two primary consumers of electrical power within the chiller to operate at the lowest power level required to meet the current load. Dynamically controlling the water pump speed and compressor speed independently of each other helps us to achieve the highest levels of performance. In addition, Chiltrix offers DC-Inverter indoor fan coil units further reducing electrical power consumption (along with lower sound levels).

Working together, the variable speed compressor, variable speed pump, and variable speed indoor units all operate at the most efficient level of power consumption possible to meet the demand. from 25% to 100%, the CX30 is always exactly the right size for the job. Under varying real-world conditions the CX30 chiller can efficiently operate at the capacity needed and can achieve up to 40-50% electrical savings each year compared to a standard chiller or air conditioner.

Beginning April 2016 - We have added an optional MODBUS Interface

Beginning September 2016 we willl offer a (DHC) Dynamic Humidity Control option. Stand by for details!

All prior systems will be forward compatible for MODBUS and DHC.

Extreme Energy Efficiency that Pays for Itself Quickly

Chiller heating and cooling is inherently efficient, and lower electricity costs are one reason why chillers are used in all large buildings.

But, small chillers have historically been unable to provide a strong ROI due to high equipment costs and unrealized efficiency potential.

Not any more. Meet the Chiltrix modular chiller family where we have chillers as small as 2 tons, with a IPLV cooling COP above 5 and NPLV heating COP of above 6. And, installed system costs are about the same as a regular air conditioner.

Save 40% or more on utility costs. The CX30 can run on less energy than a SEER 30 system.

This is not your daddy's chiller. See what's different:

Old news: Chillers are only for large systems of 30 tons or more. Chiltrix chillers start at 2/2.5 tons. And they are variable capacity, so they can run as low as half-ton at times when that's all that is needed.

Old news: Chillers are expensive to buy. An installed Chiltrix chiller system costs no more than a standard AC system.

Old news: Chillers only provide cooling, you need a boiler for heat. Chiltrix chillers are reverse cycle chillers (heat pumps) and can provide heat down to -14F (-25C) They can also connect to an existing boiler system and serve as a lower cost primary  heat source.

Old news: Chillers cannot quickly switch between heat/cool modes. The CX30 can switch modes within 15 minutes.

Old news: Chillers require a cooling tower & have maintenance issues. Our chiller uses no cooling tower, and is a sealed, maintenance free system.

Common Misconception: Chillers consume water. Chiltrix chillers don't consume any water. Water is only used on the distribution loop. Cooling is performed by a R410a compressor.
