Donper Compressors have the following types:
1. Donper Piston Compressors
Application: Suitable for domestic refrigerators, freezers and some commercial refrigeration equipment.
Characteristics: Compressing the refrigerant by the reciprocating motion of the piston in the cylinder.

2. Donper Rotary Compressors (including rolling rotor compressors)
Application: Widely used in domestic air conditioners, refrigerators and small commercial refrigeration equipment.
Characteristics: The use of rotary motion for compression, with small size, light weight, smooth operation, low noise and other advantages.

3. Donper Scroll Compressors
Application: Suitable for high-end household air conditioners, commercial air conditioners and some refrigeration equipment with high requirements for noise and vibration.
Characteristics: Using two scroll discs to engage with each other to achieve gas compression, with high energy efficiency, smooth operation and low noise.

4. Donper Inverter Compressors
Application: Suitable for air conditioning and refrigeration equipment requiring precise temperature control, such as inverter air conditioners, high-grade refrigerators.
Characteristics: By changing the operating frequency of the motor to adjust the speed of the compressor, thus achieving more precise temperature control and higher energy efficiency ratio.

Main series of Donper compressors
D series
Characteristics:
Using R134A or R600A as work material, mainly used in water dispensers, small refrigerators and small freezers.
Light weight, small size, high reliability, low noise and vibration.

Characteristics:
Using R600a or R134a and is mainly used in water dispensers, small refrigerators, and small freezers. Characterised by light weight, small size, high reliability, low noise and vibration.

L Series
Characteristics:
Suitable for use in refrigerators and freezers using R600a or R134a. This compressor features light weight, small size, high reliability, low noise and vibration, good starting performance, and excellent low temperature performance.

E/QD/NE/NB Series
Characteristics:
Supporting a variety of refrigerants such as R600a, R134a, R22, R404a, R290, etc. It is suitable for refrigerators, freezers and ice machines. Its crankshaft is single-point supported, and the whole movement is supported by four compression springs, which reduces vibration, and the unique muffler chamber design and shell design minimises noise.

CT Series
Characteristics:
Suitable for use in commercial refrigerators, commercial freezers, and display cabinets with refrigerants such as R134a, R22, and R404a. It is characterised by light weight, small size, high reliability, low noise and vibration, and good low voltage starting performance.

CJ Series
Characteristics:
Suitable for use in supermarket display cabinets, ice cream machines, commercial kitchen equipment with refrigerants such as R22 and R404a. The motor is top-mounted for easy pump cooling, which improves the reliability of the compressor; its crankshaft is double-supported, which improves the service life of the compressor.
