AEG type electrical heater units are designed for use with circular ducts, to heat the air stream passing through.
The units incorporate specially manufactured heating elements. Each unit has 2 thermostats connected to each other in series to provide security against overheating during operation. The first thermostat (adjustable type) cuts the current in case of overheating, and starts the operation again when the unit cools down. In case of first thermostat failure, the second thermostat cuts the current to provide definite protection until the reset buttons pressed.Depending on demand, electrical connections are produced gradually. The electrical connections are made via the terminals in the terminal box on the product on the field.
