New evaporator technology for air conditioning systems and process cooling with the BITZER hybrid falling film evaporators. The company is presenting a new evaporator technology.
hybrid falling film evaporators
The BITZER hybrid falling film evaporators, which are available in five housing sizes, achieve significantly better levels of efficiency than dry expansion evaporators in full and, especially, in part load operation with stable operation under all conditions thanks to optimized internal liquid droplet separation, less refrigerant charge and improved oil recovery.
With a capacity range of 300 to 2,000 kW, the hybrid falling film evaporators offer flexibility and a variety of fields of application above all, in air conditioning and process cooling. They are developed for refrigerants R134a, R1234ze, and R513A.
liquid refrigerant
BITZER hybrid falling film evaporators require at least 35 percent less refrigerant than flooded evaporators
Due to their special design, the BITZER hybrid falling film evaporators require at least 35 percent less refrigerant than flooded evaporators.
The design ensures that the shell side is not simply flooded with refrigerant. Instead, liquid refrigerant is accurately distributed on the pipe surface and only a small part of the shell side is flooded.
future-proof system
With hybrid technology from BITZER, users make their systems future-proof. As they enable systems to already meet future efficiency requirements of the EU Ecodesign Regulation. For cooling systems with an output of more than 400 kW, the minimum efficiency required by the regulation will shift the choice of dry expansion evaporators to flooded evaporators with higher efficiency.
Hybrid falling film evaporators are regarded as the evolution of flooded evaporators. They also require low maintenance cost – effectively because they operate fail-safe under all operating conditions.
