Product features

  • Low temperature protection: Equipped with a built-in heater and a potted electronic unit, this sensor is designed to function in extremely cold environments, with temperatures as low as -60°C (-76°F).
  • 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.
