The Chiltrix chiller does not consume any water and works in all humidity conditions. It uses a ultra-high efficiency DC-Inverter variable speed compressor with a small amount of R410a refrigerant self-contained in the outdoor unit. The water or water/glycol fluid is only used in a sealed loop, to transfer heating or cooling between the outdoor unit and the indoor units. Actually, a chiller is defined as a split system where water or water/glycol lines connect the indoor equipment to the outdoor equipment.
In general, the Chiltrix chiller can support any number of indoor units, that together, do not exceed the BTU capacity of the chiller(s). It is also possible to use more indoor units than the math supports, as long as you realize that they cannot all run at full speed at the same time and still deliver the expected cooling or heating. For a list of all available indoor units and their BTU ratings please see chiller indoor units. You can select HW (standard efficiency 220v) or CXI (ultra-high efficiency 120v) indoor fan coil units from Chiltrix, or use any standard chiller fan coils.
The Chiltrix is a modular chiller consisting of one or more outdoor units under common control and operation. It is possible to combine up to 10 chillers although it generally makes more sense to distribute the outdoor units in groups of 1, 2, or 3 and then locate the groups closer to the load. Server room versions are available in N+1 redundancy configurations. If using the Psychrologix DHC controller, note that it supports up to 3 chillers per controller.
We also offer ducted AHU (hydronic air handler units) for ducted systems made by FirstCo. These connect into a ducted system in the same manner as a regular AHU. You can see more information here. In addition, you can use any standard fan coil ducted unit/hydronic air handler of the correct capacity that you may purchase on the open market, they are available through most HVAC supply houses. Please contact us to help sizing this type of unit as the sizing will be non-standard.
Once you have experienced the comfort and efficiency of in-floor heating, you may never again be satisfied with any other type of heating. Chiltrix is highly compatible with hydronic floor heating and is designed to deliver an optimum floor heating experience.
There is no US DOE, EnergyStar, or other SEER test or rating for chillers. Chillers are rated with IPLV. IPLV is to chillers what SEER is to standard air conditioners. It's the official AHRI efficiency rating and it's the only rating that matters for chillers. IPLV is the industry-standard way of measuring the overall efficiency of a hydronic (chiller) cooling system. IPLV stands for Integrated Part Load Value, it's a similar concept to SEER, where part-load performance is measured and rated so that customers can have a way to do an apples-to-apples comparison of real-world operating efficiency between various brands and models. IPLV and NPLV are specified in AHRI 550/590. See the product page or spec sheet for the IPLV / NPLV of the specific chiller. See a more complete explanation of IPLV See a chiller IPLV comparison chart that shows how we stack up against the competition.
Like all air conditioning systems, when the cooling coils are below the dew point, dehumidification is performed. The Chiltrix system performs strong dehumidification comparable to a standard air conditioning system. And when used with DHC (Dynamic Humidity Control) the Chiltrix system can lower the coil temperature well below the standard condition to perform hyper-dehumidification.
The Psychrologix™ is a very unique and special controller. It is a programmable indoor controller that automates many features such as chiller reset, auto-changeover from cooling to heating, alarms, vacation mode, and many other features and includes the DHC (Dynamic Humidity Control) function. Note, this controller is not a thermostat, all thermostat functions are handled by the individual fan coil unit thermostats or in the case of ducted systems, by a standard thermostat.
DHC control can automatically manage the chiller cooling parameters to increase or decrease, or stop, dehumidification. If indoor humidity rises, the system can automatically decrease the coil temperature to a lower temperature so as to perform accelerated dehumidification. During times when humidity is within the ASHRAE recommended range, the DHC will "turn off" dehumidification, allowing the system to continue to manage sensible (regular thermometer) temperature at a greatly reduced power consumption level. Indoor humidity occurs after an event such as a exterior door opening on a humid day, or taking a hot shower. Once removed, humidity will not increase again on its own, until the next humidity event occurs. Chiltrix's efficiency can increase up to 50% above it's exceptionally high official EER ratings during periods when dehumidification is not needed.
The chiller outdoor unit needs a stable mounting position like a concrete pad, a power connection, and insulated water lines connected to the indoor unit(s). Usually 1" PEX flexible water lines are used for this. No refrigeration technician, gauges, extra refrigerant, or special tools are needed. Mainly, you need an electrician to provide a 208-240 50/60Hz power connection of >/= 15a (per ODU) and then make your water line connections. Each indoor unit is powered separately using standard household power (available as 120v or 208-240v, please review the specs of the selected indoor units). Other than that, you will install the water lines and may add a small expansion tank, some fittings, etc. depending on the design. Longer water line runs or complex routing may require a small booster pump which we can provide, contact us with your design to confirm. Recommended for water lines is oxygen-free PEX which is available from Home Depot or Lowes, etc. Standard loop design using accurate measurements can naturally achieve a system pressure balance. See chiller installation manual.
There are two ways that the Chiltrix chiller can work with solar, you can use either or both of these methods. The chiller can be integrated into a solar thermal/hydronic heating or solar water heating system and provide low cost heat at times when the sun is not available or when the load exceeds what the solar system can provide. Secondly, the Chiltrix chillers are ideal for powering with off-grid or grid tied PV solar panels. It's ideal because it uses much less power to operate than other similar sized air conditioners or heat pumps, and it has a "slow start" function that eliminates the initial in-rush surge of current. The unit starts at only <2 amps and slowly builds up, protecting batteries and inverters from sudden high amp surge loads. The unit requires AC power which can be supplied by an inverter. See example solar chiller designs.
This capability is another thing that makes Chiltrix unique among mini-split systems since the backup heat can be seamlessly incorporated into the system, avoiding, for example, the need for portable heaters. Like all heat pumps, heating capacity is reduced as outdoor weather gets colder. If you live in a very cold climate you may need backup heat occasionally. The simple way to add backup heat to a Chiltrix system is to use a normal water heater (like from Lowes or Home Depot) installed on the supply line. When backup heat is needed, the chiller can control the tank heater. .
We don't specifically offer our chillers as water heaters however they can do a great job of heating water. In this case, the chiller connects to a "heat exchanger tank" - this is also called a "solar" or "indirect" tank. It is a hot water tank with a heat exchanger coil inside. You will also use an electronic valve ordered from Chiltrix called a DN25-DHW valve. The chiller monitors the tank temperature using an included sensor. The chiller can temporarily switch from its normal cooling or heating function for a brief interval, to quickly heat the water tank whenever the tank needs heat. This is very advantageous, as water heated by the chiller can use between 60-80% less energy than a standard electric water heater would use for the same amount of water heating.
Yes, the Chiltrix chillers can provide very low cost heating when compared to an electric, propane, or oil fired boiler. You can configure the chiller as primary and only run the boiler if needed.
It's perfect, actually the Chiltrix chiller development started out as an effort to design the worlds most efficient air conditioner for small computer rooms/server rooms, and it succeeded beyond our expectations. The server room version also has an available "free cooling" option that in cold weather, can allow the system to run at its full rated capacity with the compressor off, running only fans and water pump saving a large amount of energy cost without bringing in any outside air. Free cooling COP can be as high as 41 (EER 140) during cold weather periods. See more info on free cooling. In addition, the stackable design of the Chiltrix chiller system allows for a highly redundant N+N configuration.
The system is designed for global use and is therefore very flexible. It can use voltage between 208v to 240v, and can use either 50Hz or 60Hz power. Indoor units (IDUs) are a little different - we offer 60Hz IDUs for 110v to130v. We also offer a 208-240v unit that can run on 50Hz or 60Hz. So wherever you are and whatever kind of power you have, we have a solution.
The chiller uses R410a in the outdoor unit (ODU).
Unlike chillers that have a cooling tower, the Chiltrix chillers are air cooled like a regular air conditioner. It is a sealed unit, there are no user-servicable parts inside and no need for servicing the ODU. The indoor units need to have their filters removed, cleaned, and re-inserted on a regular basis. You can determine the frequency of this requirement based on the filters appearance (and your air quality).
The system is engineered using best-of-breed components sourced from top providers around the world. German brand VSD water pumps, USA valves, heat exchangers from (SWEP) Sweden and (Multi-Stack) Australia, electronics from Japan, Mitsubushi compressor, and the list goes on. All components are selected based on reliability and performance. The system is easily serviceable and is designed for a 20 year lifetime.
The standard system is designed for low ambient heating and cooling, and supports standard high ambient cooling conditions. Heating is available from as low as -4F (-20C). Cooling range is rated up to 122F (50C). The unit can provide cooling at a reduced capacity up to 138F (59C).
There is no refrigerant lineset needed or used with the Chiltrix self-contained chiller. All of the indoor units are connected to the chiller using standard insulated CPVC or PEX (or similar) water line. The water line can be any length up to hundreds of feet. To calculate the actual distance we need to know the plumbing design and which indoor units are being used (so we can know the pressure drop spec). But regardless, an inexpensive Chiltrix-provided variable speed booster pump controlled by the chiller can provide a virtually unlimited allowable line distance.
The Chiltrix Limited Warranty is 5 years on the compressor and 2 years on other components. See warranty.
The unit is fully certified for USA and Canada and has obtained approval under UL 60335-2-40 and CSA 22.2. These certifications are recognized in over 90 countries worldwide. If you need other international certifications such as SAA, CB, CE, SONCAP, etc. we can provide any of these on quantity orders.
Further, the CX34 is AHRI-certified. AHRI is the official, independent 3rd party testing & certification organization used by the global HVAC industry and by government regulators worldwide. When AHRI certifies that a unit has a particular capacity or efficiency level, this certification is indisputable evidence that the performance stated by the manufacturer is accurate.
The CX34 is also certified by the US Department of Energy and the California Energy Commission (Titles 21, 24).
Please see the chiller air conditioner price list.
Whether it is used for a compressor, a pump, or a fan motor, DC Inverter motors are recognized as being more efficient, mainly because they use less power and can infinitely adjust their speed in real time to match the current demand. They also run cooler, last longer, and make far less noise.
DC Inverter motors actually have no inverter in them, this is a poor name that was applied years ago and has remained in use. Actually, AC power runs through a rectifier circuit converting it to DC power.
DC inverters are not only more efficient at a given speed, but having the ability to match the speed to the current application saves even more power.

Chillers use much less energy, and also use 50% to 90% less refrigerant to accomplish the same amount of heating or cooling. That's because no refrigerant lines are used inside the building to distribute heating and cooling - this is done by a water-glycol mix. All of the refrigerant stays in the outdoor unit.
That means that lineset length is virtually unlimited. It also means there are no high-pressure lines inside the building, which is a good thing for safety.
Self-contained chillers like the CX30 are user-installable, meaning no refrigeration technician or special tools are needed for installation, resulting in a perfect DIY application..
