HOLTOP/AIRWOODS AS-EC type electric preheater

HOLTOP electric pre-heaters are designed for ventilation systems where safe pre-heating of outdoor air may be necessary during winter. Thanks to the design that can be built into the pipeline, they can be easily integrated into existing ventilation systems.

The pre-heating device can be installed in the branch that introduces fresh outdoor air into the ventilation device, so that if necessary it can preheat the incoming air and avoid icing of the ventilation device or some of its parts. This protects the system, and in the case of a heat recovery device, the heat exchanger, thus ensuring the efficient, continuous operation of the system.

The preheater must be installed in such a way that it can only work when the ventilation device is operating and fresh air is introduced into the building through the preheater.
