26TECHNICAL 26 HEATING DATASHEET COMPACT SEMICONDUCTOR FAN HEATER CSF 028 | 250 W, 400 W >>Small, compact design >>Integrated pre-set thermostat >>Dynamic heating up >>Quick connection >>Clip or screw flange fixing The compact fan heater prevents formation of condensation and provides an evenly distributed interior air temperature in enclosures with electric/electronic components. The touch-safe plastic housing and the small dimensions makes it ideal for use in enclosures with high packing density. The CSF 028 is equipped with a preset thermostat. It is connected via external clamps. The fan heater is available with two different mounting systems - either mounting by screw flange or by clip. The robust screw flange fixing is particularly suitable for applications with high vibration. CSF 028 with clip fixing TECHNICAL DATA CSF 028 with screw flange fixing Art. No. clip fixing Art.

It can easily be clipped onto the protective grille of the fan heater without use of any tools, and diverts the exiting warm air by 45. This results in an overall improved heat distribution within an enclosure or cabinet. The temperature above the protective grille is reduced by up to 20 C (measured 100 mm above protective grille) and may make the use of a heat conduction plate obsolete. Air duct Art.
