Electric duct heaters designed for heating supply air in round ventilation systems.
The housing and junction box are made of galvanized sheet steel and the heating elements are made of stainless steel.
The heater is equipped with two thermostats to protect against overheating.
The heater design allows it to be placed on circular ventilation ducts using clamps, in any position, in addition to placing the dashboard down (danger of condensation accumulating).
