Semi Flooded Operation & Zero Superheat

With increased focus on the use of natural refrigerants, HB Products has developed a new system for controlling all types of evaporators on refrigeration / heat pump systems. The system is available in several variants, for example, where you can connect an expansion valve directly to the sensor which thus act as a closed loop control system.

A revolutionary new patented technologies are now ready to solved one of the main challenges when using CO2 refrigerant, CO2 refrigerant is very dynamic and reacts strongly on even small pressure / temperature changes. Now it is possible to measure the dryness of the vapor and achieving balanced dryness of the evaporated vapor in the evaporator outlet with minimum Super-heat, thereby controlling the evaporator capacity much faster and more accurate relative to the evaporator load with close to zero Super-Heat (range of 0.5 to 1.0 ̊K).
