Electric circular duct heaters/preheaters with PTC heating elements for ventilation systems EHC ../PTC

The electric circular duct heaters/preheaters with PTC heating elements EHC ../PTC are intended to heat clean air in the ventilation systems. Also, heaters/preheaters EHC ../PTC can be used for heating or preheating functions with air-handling units. The heaters/preheaters EHC ../PTC can be supplied with or without an installed electronic controller, with a pressure and/or flow monitoring system, with a contactor, or produced according to the client's requirements. The heater/preheater EHC ../PTC cases are produced from aluzinc-coated metal sheets, sealing rubber for a tight connection with the ventilation duct system.

The heater’s standard temperature setpoint is (0...+30). The other temperature setpoints are possible according to a client’s requirements.

The preheater’s standard temperature setpoints are (-10...+20) and (-30...0). The other temperature setpoints are possible according to a client’s requirements.

Preheaters are additionally insulated.
