Heaters

Compact blown-air heating resistor to maintain a constant temperature inside cabinets and
enclosures containing electrical and electronic components. Prevents the formation of
condensation or ice. Thanks to their reduced dimensions and anti-touch casing, this heating
resistor is ideal for installation in enclosures and cabinets with restricted space. CSF 028 is
equipped with a pre-set thermostat. Connection via external terminals. The resistor may be
installed in two ways: by threaded bracket or by clip. Mounting by threaded bracket is highly
robust and is particularly suitable for applications subjected to strong vibration.
