Small Horizontal Air Handlers

Note: When sizing conventional air handlers for use with Chiltrix air-to-water heat pumps (or any high-efficiency, low temp AWHP) it is important to consider the capacity implications. For example, air handlers are generally rated for cooling at 44F entering water temperature. That’s also fine for Chiltrix, however, if you equip your Chiltrix with DHC (dynamic Humidity Control) it is advisable to use the extended data we provide and size the air handler for the non-standard DHC temperature, generally to be able to meet the sensible load at 54F EWT(Entering Water Temperature). Likewise, for heating, most air handlers are rated for 180F EWT which will never be possible for a low-temp AWHP so you must size the fan coil based on both the heat pump manufacturer’s published performance data and the air handler’s non-standard temperature de-rate document.

Important Note About Mini-Duct / Ducted Systems

We are happy to help you select the proper model based on BTU capacity and/or CFM for ducted or concealed hydronic air handlers to be used with the Chiltrix air-to-water heat pump, and we publish the static pressure capacity. However, any questions regarding duct design, etc. must be addressed by your professional installer and are not supported by us. Please confirm  duct design with your HVAC installation professional.

Additional Fan Coil Options

If you don’t prefer a ducted system or to use concealed ceiling fan coil units, consider our ductless room fan coil units for better efficiency and individual room zoning. Note, you can also mix and match – for example, you may decide to use a ducted or concealed ceiling fan coil in an  open area of your home such as a  great room or combined living room-dining room-kitchen, and then also use ductless room fan coil units for bedrooms, office, den, or other individual rooms. In addition, either ducted or ductless, or a combination of these, can be used with radiant heating, domestic hot water, etc. Chiltrix has a wide selection of ducted and ductless units to select from.
