The CS 028 / CSL 028 fan heaters prevent formation of condensation and provide an evenly distributed interior
air temperature in enclosures. The heaters are connected using the internal terminal connectors. The surface
temperatures on the accessible side surfaces of the housing are minimized as a result of the heater design. The
small size of the CS 028 / CSL 028 heaters make them ideal for use in enclosures where space is at a premium.

ACCESSORY PART FOR FAN HEATER CSL 028

Air guide for improved heat distribution

The air guide is an accessory part for use with the fan heater CSL 028.
It can easily be clipped onto the protective grill of the fan heater

View: back side

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 68 °F/20 °C (measured approx. 3.9”/100 mm above protective
grill) and may make the use of custom heat ducts obsolete.
