A pre-heater is available as an accessory for Topvex units of model SC20-70 and TC20-70 with counterflow heat exchanger. The pre-heater can be used to lift the inlet temperature into the air handling unit. The pre-heater will act with supporting capacity during conditions as by pass defrosting or during low outdoor temperatures, to secure desired supply temperature.
The pre-heater is controlled from the integrated control system in the Topvex unit, Systemair Access, with a dedicated pre-heater function offering set point to actual needs.
