Recuperator. Water heater/cooler

Cooling: If cold tap water is placed through the unit, it will cool supply air and the water will become preheated.

The NW-1 duct heater has a built-up lamel heat exchanger – liquid/air that has to be connected to CO network. The heat power of the device is dependent on temperature of water that supplies the exchanger, volume of water stream that flows through the exchanger and on the air volume flowing through the heater and in the time unit (for the below presented case the heat power of the device is 2,37KW).
