Electric heating coil (HE)

HE heating coil is an accessory for the VEX4000 series and is used to increase the temperature of the supply air

Function and application

The coil is used to increase the supply air temperature and works by supply air passing over the electrically heated heating elements in the coil. The supply air absorbs the heat from the heating elements and thus achieves a higher temperature.

The coil can either be controlled by the EXcon control system or supplied for connection to a third-party control system.
