Core Technology

Two-Stage Air-Cooled Compression Unit

The rotor has no slip and requires no excitation current. It has no fundamental iron or copper losses in the rotor and generates less heat, reducing stator current and resistance losses. Its efficiency is 5%-8% higher than asynchronous motors of the same capacity, especially maintaining high motor efficiency at low speeds.

Synchronous Motor Stepless Speed Regulation

Electronic speed regulation is applied in the two-stage compression, enabling synchronous stepless speed control for both first and second-stage units to meet various requirements. The motor efficiency is 95.5%, saving 4.1% energy, providing high torque and smooth operation.

Energy-Efficient Line

Through in-depth analysis of energy-saving needs and continuous optimization of product structure, Xinlei's technical team has been upgrading the V series line with years of technical expertise. This line is one of the most energy-efficient screw compressor lines, featuring high volumetric efficiency, reasonable drive contact points, and a small area of the discharge side leakage triangle.

Machine structure

High-Efficiency Filtration System

High-efficiency oil-gas separator ensures oil content in discharge air is below 3 ppm.

High-precision oil filter guarantees optimal oil supply to the airend, providing better protection and extending its service life.

High-efficiency vertical air filter keeps the internal system clean, protecting the airend rotors and bearings from wear, and prolonging the life of the lubricating oil.
