SP Series Semi‑Hermetic Reciprocating Compressor
SP series compressors are widely used series compressors. Available in 2/4/6/8 cylinders models with power range of 3~70HP, they are not only suitable for various commercial and industrial refrigeration applications but also for A/C applications. With new concepts and designs, the SP series support the use of natural refrigerant R290 and other eco‑friendly refrigerants. Whether for modern buildings that prioritize energy efficiency or industries with stringent requirements for refrigeration quality and environmental protection, the SP series compressors stand out as an ideal choice due to their reliability and flexibility.
-
- Balanced crankshaft designed based on rotor dynamics, offering sufficient rigidity and reducing vibration.
- Cylinder liner honed by special process, ensuring low friction and good lubrication for low power consumption.
- Patented suction and discharge valve plate structure, to reduce fluid resistance loss and noise.
- High‑efficiency PW motor with low starting current and high energy efficiency.
- Built‑in motor protection module, dynamic monitoring, to ensure the safe operation of the compressor.
- Highly integrated safety valve, shut‑off valve, suction filter and other components, compact structure and higher reliability.
- Oil one‑way return valve to avoid oil accumulation inside the motor, ensuring oil balance.

Chichikushvili –
The piston compressor looks good. Can you ship just one unit?
LanglerCA –
What is the minimum HP model, and what is the maximum?
Dobrescu –
The shape of yours is very similar to Bitzer’s. Can it serve as a replacement for a Bitzer compressor?
