Radiant Heater and
Fan Heater series FLH
Heat generated by electrical equipment operating under load
will prevent the accumulation of condensation. After the equipment has been switched off however it cools down and gradually adapts to the ambient temperature, thus dropping below
the dew point. This is the signal that triggers the radiant heater!
These sources of heat prevent the formation of condensation
by raising the internal temperature a few degrees above the
ambient temperature.
In the interest of evenly distributing the heat, we recommend
that the requirement of heating capacity is divided among
several small heaters.
