Electric rectangular duct heaters/preheaters for ventilation systems EHR...
The electric rectangular duct heaters/preheaters EHR.. are intended to be used for heating of clean air in the ventilation systems. Also, heaters/preheaters EHR.. can be used for heating or preheating functions with air-handling units. The heaters/preheaters EHR.. 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 EHR.. cases are produced from aluzinc-coated metal sheets. The stainless steel tubes of heating elements are used in the heaters/preheaters.
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.
