The Chiltrix small air cooled chiller compressor is fully variable in capacity and its operation is continuously adjusted to match the required heating or cooling output, avoiding on/off cycling and wasted energy. When measured on an annual basis, the average energy savings produced by the Chiltrix dynamic capacity system can exceed 40-50%.
Chiltrix uses 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 the system controller using a special algorithm to keep the compressor and pump both working at the optimum speed. The variable speed condenser fan is controlled in a similar manner. This allows all of the consumers of electrical power within the chiller to operate at the lowest power level 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 and longer lifespan).
Working together, the variable speed compressor, variable speed pump, variable speed condenser fan, 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 system is always exactly the right size for the job. Under varying real-world conditions the CX34 chiller can efficiently operate at the capacity needed and can achieve up to 50% or more in electrical savings each year compared to a standard chiller, heat pump, or air conditioner. See the details of Chiltrix high efficiency chiller heat pump technology.
The Psychrologix™ psychrometric chiller controller dynamically manages humidity and automatically adjusts the parameters of the chiller in real time, for an off-the-charts increase in efficiency (above its already high rating) when dehumidification is not needed. DHC (Dynamic Humidity Control) can automatically lower the indoor unit coil temperatures to quickly remove any humidity increase. When humidity is within acceptable limits, the system will dynamically reconfigure itself to the most efficient possible operating parameters allowing the chiller to run well above its rated efficiency. The Psychrologix™ chiller control option also adds a wide range of programmable and automated features in addition to DHC and can manage up to three chillers. See the Psychrologix™ DHC controller details here. See the detailed chiller controls white paper here.
The Chiltrix air cooled chiller can also connect to a hot water heat exchanger tank and provide domestic hot water, summer or winter. Save up to 70% or more each year on your water heating costs using our high efficiency heat pump to heat your water. Requires a heat exchanger tank (or a solar tank).

Psychrologix™ Psychrometric Controller w/ DHC
Chiltrix small air cooled chillers with Psychrologix™ control use a unique psychrometric controls approach coupled with variable speed compressors, variable speed pumps, variable speed fans, etc. The Chiltrix chillers match their capacity to the load so precisely that often buffer tanks are not needed. Not only is capacity matched in real time, but the parameters are continuously adjusted in response to conditions. For example, when more dehumidification is needed, the Psychrologix™ DHC controller lowers the indoor unit coil temperature to remove more humidity. When humidity is under control, the system raises the coil temperature to a more energy efficient temperature that still provides the needed cooling, but does not remove as much humidity, or may at times remove no humidity at all if humidity is already low enough.
Humidity removal (dehumidification, or latent heat removal) is very energy intensive and consumes a large part of the total energy used by an air conditioner. When needed, dehumidification is a good thing and the Chiltrix chillers do an outstanding job of humidity removal. Chiltrix chillers with psychrometric controls can also automatically perform hyper-dehumidification by increasing humidity removal to levels that surpass those of a normal chiller or air conditioner, if needed, to deal with extra high humidity.
Humidity does not pass through walls like heat, it requires an air flow from a more humid area, like for example, a door opening to the outside on a humid day, or an internal source such as a steamy hot shower or people exercising, etc. Once indoor humidity is under control and within the user-defined range, humidity should remain low for extended periods without additional dehumidification unless additional humidity is introduced into the space. During periods when humidity is in range, the Psychrologix™ DHC controller will automatically adjust the chiller parameters to provide thermostat cooling, but not provide dehumidification. Turning off dehumidification saves a very large amount of energy when conditions allow.
Simplified Efficiency & Humidity Example::
The CX34 IPLV EER, at the industry standard chiller loop temperature of 44F, is around EER 21, exceptionally high when compared to standard systems. However, when humidity is under the set limit, there is no need to operate the loop at 44F when at 54F, thermostat temperature settings can still be maintained, and average efficiency rises to ~EER 30. So when indoor humidity is under the user-defined limit, the Psychrologix™ controller allows the system to run at a more efficient temperature. In some cases, the loop may be adjusted as high as 62F producing average EER as high as EER 35. And likewise, if humidity is particularly high, the system loop may be dropped as low as 40F to perform hyper-dehumidification. In this manner, both system efficiency and humidity are dynamically controlled.
Bottom Line - The Chiltrix chiller is the most energy efficient heating and cooling option you will find, with the highest IPLV rating in the market, even without the Psychrologix™/DHC. But with DHC running, efficiency can at times be more than 47% higher than the IPLV rating.
Note - the Psychrologix™ controller is not a thermostat - it is a programmable psychrometric chiller controller. Thermostat settings are still made in the usual way, either set individually at each room fan coil unit, or in the case of a ducted system, by a standard central thermostat.
The Chiltrix chillers are ideal for a solar PV powered installation whether grid-tied or off-grid. While the chiller needs AC power and therefore must connect to the solar energy source (or batteries) via an inverter, the CX34 is the best possible choice for this type of application.
Below is an example diagram of a solar integrated heat pump chiller system. Not shown, in-floor hydronic heating can be used in place of or in addition to fan coils.

Robotic welded stainless steel tank construction is used for both inner and outer tank These professional grade insulated water tanks are designed for use with chillers, radiant heat, hydronic heating, & floor heating applications. See buffer tank spec sheet. These hydronic buffer tanks are also perfect for use as a wood boiler buffer tank.
The Chiltrix heavily insulated small chilled water / hot water / boiler buffer tanks are tall and thin so they are perfect for thermal stratification as well as applications where a small floor footprint is required (18.5: diameter). Multi-port design allows a wide range of uses.These stainless steel tanks are designed as a multi-purpose tank, they can be used an as accumulator tank, a buffer vessel, a volume expander tank, a backup heating tank, boiler buffer tank, etc. They are often used with chillers and hydronic heating heat pump systems as buffer (hydraulic separation) tank.
DC-Inverter fan motors run more efficiently and use less power than regular fan motors. Additionally, they are far quieter than a standard fan unit, you can hardly hear them running. And using a hermetically sealed fan motor means years of trouble free service because dust, salts, acids, and moisture cannot get inside. Did we mention more efficient? DC-Inverter fan motors use up to 75% less electricity to do the same job. Chiltrix Ultra-Slim DC-Inverter CXI FCUs are 110-130V 60Hz.
Chiltrix DC Inverter Fan Coil Units
The Chiltrix CXI-series FCUs are the thinnest and quietest ductless chiller fan coil units available. They also use far less electricity to operate than any standard fan coil unit. The HW series is a standard high wall design of standard efficiency. The Chiltrix CX-series chiller heat pump units can work with nearly any brand of fan coil unit, ducted or ductless, as well as hydronic in-floor systems.
Central Ducted Hydronic Systems:
Ducted forced air systems are less efficient than ductless fan coil units due to static pressure drop and duct thermal loss. Ducted systems require a centralized thermostat,and cannot take advantage of individual zones in each room like a ductless system. In new construction, or when adding air conditioning to a building that has no current duct system, the installed cost of a ductless system will be about the same, or less than, installing with a duct system. However, if a central ducted system is your best choice, the Chiltrix system combined with a FirstCo DC-Inverter powered VMB will be your most efficient choice
