ChillX Chillers

ChillX Premium Water Chillers

ChillX premium water chillers are built using the highest quality components, including stainless steel reservoir, 1/2" foam insulation, and custom refrigeration evaporators manufactured in-house. Every ChillX water chiller is load tested and must produce at least 110% of the BTU rating for that system -- guaranteed! Our custom evaporators are as much as 20% more efficient than any other chiller on the market today!

A great deal of research, engineering, and creativity goes into every product offered by ChillX. Built in the USA by expert craftsman, ChillX chillers are custom designed by a team of engineers with decades of experience in all manner of commercial refrigeration applications. You won't find a more thoughtfully considered chiller solution anywhere else.

CHILLX Premium Water Chillers

The Most Efficient cooling solutions
For Your Environment.

ChillX - Closed Loop Evaporative Fluid Cooler - Front

Our evaporative fluid cooler systems can be deployed in a number of applications, and in hybrid/combinations including:

Affordable Stainless Steel Brazed Plate Heat Exchangers

These stainless steel brazed plate heat exchangers are compact, efficient, durable, quite versatile, and are among the best value products we offer. These heat exchangers can be easily coupled with chilled or hot water systems to serve a wide array of applications.

Our ChillX water-cooled heat pump air conditioners are amazingly efficient, easy to use, and simple to install. We recommend coupling them with our evaporative fluid coolers or pond loop heat exchangers for ideal condensing temps and maximum equipment longevity with pristine closed-loop condensing water. However, they're also also frequently used with clean well or tap water in open-loop systems, or with other geothermal ground loop systems. These units are all built in the USA.

ChillX - 2-10 Ton Water-Cooled Air-Conditioners
Rheostat Fan Speed Controller

These Rheostat fan speed controllers are an easy and inexpensive way to provide variability to the output of your unit heater, as well as modulate fan noise. They're compact, light weight, and can be used with just about any kind of fan or high velocity blower.


  • Three Settings: Off / Full Speed / Variable Speed (High-Low).
  • Heavy duty HDPE construction for durability.
  • Easy to install and use!
  • Built-in and easily replaced 15A fuse.
Dayton - PSC Squirrel Cage Blower Fans

Dynamically balanced blower mounts in any position and operates with minimal noise and vibration, to maintain CFM at higher static pressures. Open motor has cast-aluminum end shields for greater heat dissipation, resulting in less downtime and longer service life. Ball bearings. Not for use with speed controllers.

ChillX - 1.5 - 12 Ton Vertical Extra Low Temp Chillers

Our most robust commercial multi-temp (range) chillers offer a number of performance advantages and upgradable features beyond our simpler compact and budget designs. Most of all, these vertical recirculating commercial units provide the most efficient range of operating temps even at high ambient, and with an upgrade to R404A these units can produce a wider range of low temps as well. By default, this line of chiller includes a recirculating tank design which does require a second process pump to attach to your devices.

Hygge - Side-Arm Heat Exchanger

This is a 48" tube-in-tube side-arm heat exchanger with 3/4" hook up for the domestic water heater side, and 1" hook up for the wood stove/boiler side. This side-arm will work on any size hot water heater, though installation piping may vary depending on water heater dimensions. The inner copper tube is rifled in order to introduce turbulence within the heat exchanger which improves heat exchange performance. The side-arm comes dry-fit/unsoldered to more easily fit your exact installation.

RAUPLATE - Below-floor Radiant Floor Installation System

Sold in box quantities of 20 plates only; for a total of 80 ft of plate.

RAUPLATE is an installation/mounting system for radiant heating/cooling PEX lines below-floor, between flooring joists. This is one of the most important parts of your radiant floor heating/cooling system and one of the most critical; it boosts performance and more evenly distributes heat across your floor at an ideal 8" on center. These installation plates can increase heat transfer efficiency by as much as 30%, reduce poential for vibration noise, and makes installation a breeze!

Hygge - Aquastat Probe Well

These probe wells are intended to protect aquastat probes from the corrosive harshness of most hydronic/water/glycol systems. These very simple devices will add many years to your aquastat probes vs. directly immersing probe ends into your reservoir or manifold system. Made primarily of copper, these wells are safe for potable water, easy to clean and care for, and provide great thermally conductivity for quick and accurate measurement of your system's water temps.

ChillX - 1/4 - 1 Ton Compact Low Temp Chillers W/ Res

Our Compact Low Temp (LT) chillers are ideal for the budget-minded user and too little space for larger equipment. These very efficient mobile chillers can be used at a wide range of operating temps (from 60F all the way down to 25F!) and are just as happy indoors as outdoors. These units spare no features and even come standard with caster wheels for easy mobility and a performance optimized microcontroller which makes efficient operation at very low temps possible. These units are packed with features and a great price too!
