DH

APPLICATION

Heaters DH are used in mechanical ventilation systems where there is a need to raise the temperature during winter or keep constant temperature in the room. It is possible to use heaters in technological processes that require the supply of constant temperature air.

CONSTRUCTION

Electric duct heaters designed for direct mounting on circular ducts with standard diameters (100-400 mm). The housing of the heater is made of galvanized sheet steel, and the heating elements are made of stainless steel.

The heaters are fitted with a standard double overheat protection system: automatic element (temp. +75^oC), and manual unlock (temp. +85^oC). Duct heaters should be selected so that the outlet air temperature does not exceed +40^oC. The air flow rate of the heaters must not be less than 1.5 m/s.
