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 appli cations with high vibration. > Small, compact design > Integrated pre-set thermostat > Dynamic heating up > Quick connection > Clip or screw flange fixing CSF 028 with clip fixing CSF 028 with screw flange fixing Art.

View: back side Heating capacity / Ambient temperature diagram CSF 028 Temperature (°C) Heating capacity (W) TECHNICAL DRAWINGS CLIP FIXING View: back side SCREW FLANGE FIXING Example of connection Fan heater CSF 028 Air duct for improved heat distribution The air duct is an accessory part for use with the fan heater CSF 028. 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. Art.
