Trench heater FRD with lamellar exchanger and fan, heating and cooling.

Trench heaters with forced convection via a fan provide a high heating/ cooling output. They are a suitable addition to cooling and air-conditioning units, the effect of which does not reach up to the windows. The optimal control of the forced convection is provided by fans with continuous speed control and low energy consumption. Spaces with thermal losses in winter and high thermal gains in summer are effectively regulated from the floor, without disturbing the aesthetics of the room with large-area glazing. The heaters are fitted with an Al-Cu lamellar exchanger through which the heating/cooling medium flows. Tangential fans are placed in front of the exchanger along the whole length, ensuring uniform coverage of the heat exchanger and, subsequently, optimal distribution of temperature within the room.
