Defrost Sensor for heat pumps and other outdoor applications

Technical data: HBDF-OD

The HBDF-OD is a sensor designed for outdoor evaporators, with temperature guidance capabilities in the range of -60°C to 20°C (-76°F to 68°F). However, 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.

Product features

  • Moisture protection: Features a built-in heater and a potted electronic unit to resist humidity.
  • 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.
