AGRO fan heaters are intended for operation in the rooms with especially severe conditions: increased dustiness, aggressive particles in the air. Design solutions used in AGRO 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 and the distance between slats, TREVENT AGRO can be used for a long time with no loss in quality while complying with requirements of this instruction. TREVENT AGRO 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. Before supplying the heat-transfer agent, make sure that the system is connected correctly, that the heat-transfer agent parameters correspond to the parameters in the table, and that the connections are hermetically sealed.
