HBProducts | LT Defrost Sensor for low temperature freezer application
Technical data: HBDF-LT
The sensor can be used on evaporators with minimum 5 mm fin spacing in cold rooms with temperatures down to -60°C. The sensor is protected against low temperatures with a built-in heater and potted electronic unit.
The sensor uses the steel wire only and is delivered without temperature sensor.
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
