Duct coil water heater d315

Duct coil water duct heater is used to heat ventilating air flown into rooms. It is a complete device used to being installed in the mechanical ventilation system (with the enforced air flow).
The housing is made from galvanized steel sheet. The water coil and stub pipes are made from copper; the heat exchanger fins are made from aluminium.
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
