Hitachi's various firsts
 

★ Hitachi has 40 years of experience in the R&D and production of twin screw compressors;

Twin screw compressor development history

Patented twin screw compressor technology
 

①Hitachi's sixth-generation compressor (Type A/Small Type G) adopts patented centrifugal oil separator technology;

②Filterless centrifugal structure, oil separation efficiency is 3~4 times higher than that of traditional filter separator;
③Reduce compressor exhaust pressure loss and improve refrigeration efficiency;
④Note: The large G compressor adopts an external centrifugal oil separator;

Twin-screw unit history

Nearly 50 years of experience in the design and manufacture of twin screw chillers

Low carbon environmental protection, energy saving and high efficiency

● R134a environmentally friendly refrigerant  -  zero damage to ozone
● Efficient units reduce electrical energy consumption and thus CO2 emissions; Reducing the greenhouse effect;
● The full range of products comply with China's green environmental protection directive (equivalent to EU RoHS);
● The performance of the unit is further improved, which greatly reduces the operating cost of the unit and saves expenses for customers。

Technological innovation, advanced design

●It adopts R134a refrigerant special G type semi-hermetic twin screw compressor independently developed by Hitachi, which has high compression efficiency and good reliability;
● The flooded evaporator is equipped with water flow pressure differential switch and photoelectric oil level switch as standard, which has strong anti-freezing ability and eliminates the risk of oil shortage operation of the compressor;
● The full-liquid type adopts venturi to inject back oil, no oil pump is required, which is simple and reliable;
● The condenser has a built-in supercooler to increase the subcooling degree and improve the circulation efficiency;
● Integrated design of multiple machine heads, easy on-site installation, good backup, high partial load efficiency;

Precise control, stable and reliable

●Hitachi's latest microcomputer control system is adopted to achieve smooth adjustment of the unit and higher partial load efficiency;
●Equipped with energy-saving mode, when the multi-compressor unit can implement partial load, the number of compressors put into operation is automatically controlled to improve the partial load efficiency;
● Configure the number of units control function, users can set according to the needs of multiple units, and automatically control the number of units put into operation according to the size of the load;
