HBDF is an intelligent sensor with a built-in microprocessor. It is designed to measure ice formation on evaporators (Air-Coolers). It emits a 4-20 mA signal. Apart from the 4-20 mA signal, the sensor also has built-in relays for start/stop defrost and external temperature sensor for measuring when the ice is melted.
Product Features:
Defrost starts only when needed (on demand)
Stop the defrost when ice is melted (input from temperature sensor located on evaporator surface)
Save energy compared with timer based defrosting
Gain more capacity - fewer and shorter defrost cycles
