BITZER compressors are divided into BITZER semi-hermetic screw compressors, BITZER semi-hermetic compact screw compressors, BITZER piston compressors (BITZER semi-hermetic screw compressors). Hermetic piston compressor) is specially designed for large commercial refrigeration systems or industrial refrigeration systems.
BITZER screw compressors have many technical advantages:
Large cooling capacity and high energy efficiency ratio, and can be run with an economizer
Built-in The energy adjustment device can adjust the cooling capacity of the compressor from 100 to 75 to 50%. Starting from the HSK85 model, the compressor can have stepless or stepless energy adjustment from 100 to 25%.
Starting from the HSN85 model, the compressor can have stepped or stepless energy adjustment of 100-50%
The patented lubrication system and large-size bearings ensure that the compressor Reliable and continuous operation
Suitable for various refrigerants
A maximum of 6 compressors can be connected in parallel
The displacement of the compressor is maximized 11 levels, as is the cooling capacity. Using a parallel system can bring additional benefits to customers:
The system has high reliability and the compressors are mutual backup
Stepless adjustment of cooling capacity
The compressor always works at full load, and the system has high partial load efficiency
The compressor system is compact and easy to maintain and repair. CSH and CSW series products are the best choice for the production of chillers, air conditioning units and heat pumps. These two series of products have built-in oil storage tanks and oil separation systems; compared with semi-hermetic screw compressors, this design greatly shortens the equipment installation time and minimizes installation space requirements. CSH series compressors have strong versatility and are equipped with an economizer interface and an external oil cooler interface. The latest CSH95 series compressor is equipped with a motor of more than 300 horsepower for the first time, which better meets the needs of customers in the air-conditioning industry for large-capacity compressors.
Compact screw compressors are equipped with dual energy adjustment devices, which can adjust the energy of the compressor steplessly or steplessly. Both series of products demonstrate optimal energy efficiency levels at both full load and part load. Most models can be operated with refrigerants R134a, R407C, R22, R404A and F507 – and can be operated with or without an economizer. BITZER piston compressors have been widely used in refrigeration and air conditioning for decades and are recognized as the best compressors on the market. Piston compressors are also highly versatile and are widely used in cryogenic refrigeration, air conditioning and heat pump applications. Not only that, piston compressors also use various natural and synthetic refrigerants.
According to the traditional definition of refrigeration, Bitzer's semi-hermetic piston compressors cover the entire application range of fluorine-free refrigerants and natural refrigerants. This series of products has the characteristics of durable valve group design, high-quality wear-resistant bearing components, easy maintenance, use and speed control, and smooth operation.
In addition to this, the product is equipped with a highly efficient, air-suction-cooled motor. Among them, the octagonal machine series has a very compact appearance design and more
smooth operating characteristics. For example, the 4J-13.2 compressor adopts an internal oil return system, which has been proven to be efficient
reliable after many years of application.
In applications where R22 refrigerant is used in low-temperature refrigeration, Bitzer semi-hermetic compressors can provide Varicool suction superheat control, electronic spray liquid cooling
cooling devices or dual stage compressor. The nominal power of compressor motor ranges from 0.37Kw to 74Kw.
