HB Products HBDF MK2

HB Products HBDF is a simple solution for energy-optimal automatic defrosting of evaporators. It results in energy savings of approximately 10%, thus quickly recouping its cost. The sensor measures the thickness of ice deposits between the fins and sends a 4..20mA signal to the system’s PLC.

The 4 mA signal is emitted when the evaporator is free of ice. The defrost point is set according to the evaporator type and the amount of moisture, and it is determined based on a visual assessment of the ice deposits on the evaporator. The sensor can be installed in less than one hour, on both new and old evaporators. It can be installed when the system is in operation, and therefore, system shutdown is not necessary.

Thermofrost Cryo is the exclusive distributor for HB Products in the UK.

The electronic part is mounted on the evaporator’s frame using 2 screws. The mechanical part consists of a thin Teflon-coated wire, which is installed between the fins of the evaporator. HBDF is available in 3 variants, with a 10m, 20m, and 30m wire respectively. After installation, the sensor is calibrated/configured to the evaporator it is mounted on. This is done using a PC-based software tool, which can be downloaded via this link.
