Anti-moisture heaters, to be employed inside switchboards, motor housings and any small closed space, in order to prevent moisture condensation and icing.


RFST resistors consist of a resistive core embedded in a ceramic insulator and protected with a thick finned anodized aluminium case (neutral standard; black and other colours on request).

A bimetallic thermostat is available to control heat sink temperature, connected either in series with the resistor or with alarm/control circuits.


ROHS compliant.
