HBProducts | Standard Defrost Sensor for freezer application
Technical data: HBDF-Freezer
The sensor can be used on evaporators with minimum 5 mm fin spacing in cold rooms with temperatures down to -30 to 0°C. The sensor is for dry indoor use only.
The sensor is delivered without temperature sensor and uses the steel wire only.
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
