It may be affected by rain, snow, or other forms of moisture on the evaporator surface. Given these environmental influences, the sensor serves best as an assistant or guide for a controller rather than as a sole defrosting solution.

The HBDF is a sensor designed for evaporators with at least 5 mm fin spacing, operating in cold rooms. 
It is intended for indoor use and is not suitable for wet or outdoor environments. The sensor integrates a temperature sensor for compensation

  • Smart defrosting: Stops defrost when the ice is melted, thanks to input from a temperature sensor located on the evaporator surface.
  • Simple installation: The sensor can be easily installed, even in existing sites.
  • Energy efficiency: More efficient than timer-based defrosting, saving energy and costs.
