THERM 28 CXE.AA

Modernized series THERM 28 CXE.AA of boilers can be used to heat civil and industrial structures with utility water flow heating. They are derived from the concept of existing THERM atmospheric boilers plus recent innovative elements. The boilers are constructed as consumer appliances with maximum efficiency and an emphasis on minimum emissions into the air and minimum energy requirements.

The water is heated by a secondary plate exchanger that is part of the boiler. The boiler unit includes an energy saving circulating pump so that the water flows through the heating system. The advantages of this method of heating water are the compact dimensions for small spaces and the low price of the device.
