Bitzer Screw Compressors
Principle of operation：
Screw compressors utilise the rotation of a pair of intermeshing rotors (usually a male and a female rotor) for gas intake, compression and discharge.
Common models:
CSH Series:CSH7571-160, CSH8571-200
CSW Series:CSW8571-200, CSW9571-250
Applicable refrigerants:
R22, R404a, R507a, R134a
Characteristics:
Adoption of high viscosity grade refrigeration oil (e.g. CPI BSE170) enhances low-temperature solubility and lubrication performance.
Supports a wide range of viscosity, suitable for centrifuges, piston machines and other complex systems.
Modular design, covering high, medium and low temperature applications.
Application Scenarios:
Large refrigeration systems: Industrial-grade cold storage, low-temperature reaction units in chemical plants;
Central air conditioning: Commercial buildings, data centre cooling systems.
Bitzer Scroll Compressors
Principle of operation：
Scroll compressors use two scroll discs (one stationary and the other rotating eccentrically) for refrigerant compression.
Common models:
GSD80235VA, GSD80485VA, EGX21K-05G-40S, EQ9T-05G-40S
Characteristics:
