PRO fan heaters are intended for operation in the rooms with especially severe conditions: increased dustiness, aggressive particles in the air. Design solutions used in PRO fan heaters significantly increase operational safety and extend the service life of the fan heater. Due to the use of AISI 304 stainless steel or ABS plastic body, heat exchanger with polymer protective coating, increased thickness of slats, as well as additional possibility of using epoxy coating of the heat exchanger in rooms with high requirements for chemical resistance, TREVENT PRO can be used for a long time with no loss in quality while complying with requirements of this instruction. TREVENT PRO fan heaters are an element of water heating systems. They are intended for heating the air and equally distributing it in the rooms. The principle of operation is based on the operation of the axial fan, which pumps and passes air through a copper-aluminum heat exchanger, in which the heat-transfer agent flows. The air heated in this way is directed to the work area of the room with the help of directional louvers.
Т1 - water temperature at the inlet to the fan heater Р – thermal power of the fan heater Т2 - water temperature at the outlet of the fan heater Δ – water pressure drop in the heat exchanger Т1a – air temperature at the inlet to the fan heater Qa – air flow Т2a – air temperature at the outlet of the fan heater Qw – water flow
