HBDF-30 HB Products Defrost on Demand Sensor - 30m wire

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
• Easy installation - also on existing sites
