Keller Benefits

The ProTERM features the following benefits:

The ProTERM units have normal operation and dual operation with air recirculation options. 

During normal operation, exhausted air is heated when processed.
With dual operation, exhausted air is heated when processed and the circulating air from the plant can also be heated. 

The ProTERM has a cooling effect in the summer and heating in the winter.  The outside air is directed past the heat exchanger via a bypass in the summer to avoid additional heat. Air can be cooled as well with an additional cooling battery for plant air-conditioning. The outside air can be heated by a heating battery for very cold days.

The sizable savings become apparent in a comparison of the annual heated air requirement.  Because the ProTERM has both heating and cooling effects, expenses typically spent on other heating and cooling solutions will be reduced.
