Electric duct heaters are designed for heating supply air in ventilation systems with a rectangular cross-section.
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 rectangular ventilation ducts using mounting frames, in any position, in addition to placing the dashboard down (danger of condensation accumulating).
