Unit Options

Electric Heater

Electric heaters are fitted on the fan discharge.

Heaters have two heating stages and provided with two types of overheat thermostats:

•Automatic reset thermostats which stop the electric heater when the air temperature rises to 76°C. Automatic reset at 60°C. No alarm output available.

•The manual reset thermostat which stop the unit when the air temperature rises to 120°C. No alarm output available.

Soft Starter

The soft starter is used to achieve a progressive supply fan start and a reduced starting current as well as the motor starting torque. This option is well adapted for textile duct applications. It is factory installed in the main control panel.

The soft starter gradually increases the voltage of the supply fan motor until it reaches full line voltage.

The starting time can be adjusted from 0 to 64 seconds but the soft starter is factory set to the maximum starting time value, 64 seconds.
