NORDIC Hydronic Air Handler
These NORDIC Hydronic Air Handler units are often used to provide air conditioning in buildings that have hydronic in-floor heating, in conjunction with a liquid-to-water heat pump, or other hydronic heating system. They can also be used to provide multiple-zone heating and cooling, for example in retrofit applications where in-floor heating installation is not practical.
High Yield Btu/hr at lower water temperatures
Conventional water based fan coils often require higher water temperatures. They are designed for conventional heating boilers. A distinct advantage of the NORDIC Hydronic Air Handler is that it is designed to work with the more moderate water temperatures from water-to-water geothermal heat pumps. This means that you can run your heat pump at lower setpoint. Therefore increasing the COP of your overall system and still meeting the heating loads of the building.

Nordic® AHW Series
Nordic®’s hydronic air handler is called the AHW Series. There is only one size (AHW-65), since a wide capacity range can be achieved by varying the fan speed and water flow through the unit (unlike with a refrigerant air handler).
At the highest air and water flows, it’s capable of 5 tons or more of heating, an uncommonly high capacity compared to competing equipment. See the NORDIC Hydronic Air Handler specification document or manual for detailed capacity information.
All NORDIC Hydronic Air Handler units come equipped with a condensate tray system, ready for cooling duty. The AHW is available in two configurations: a slim horizontal unit, suitable for attics or crawl spaces, and a slim vertical unit, suitable for closets or basements.
