Unified Social Credit Code: 91120111773622223A

Registered Address: No. 15 Plant, Chenxing Road, Tianjin Zhongbei Industrial Park

Production/Office Address: No. 10 Plant, Chenxing Road, Tianjin Zhongbei Industrial Park

Has been audited to conform to the following Quality Management System standard

ISO 9001:2015

This Quality Management System is valid for the

Production of oil-injected screw air compressor for general use

(power 7.5 ~ 355kW, exhaust pressure ≤1.25MPa) and micro

reciprocating piston air compressor (power 0.37 ~ 15kW,

exhaust pressure ≤1.4MPa)

In order to ensure that our screw compressor operates as efficiently as possible, Jinjing has independently developed its own special rotor profile. Compared with other traditional rotor profile designs, Jinjing rotor can save up to 15% energy.

Our precision machined large-size roller bearings help to make our air end have a long service life. All these, together with our state-of-the-art internal manufacturing processes and strict manufacturing tolerances, provide excellent quality synonymous with the Jinjing name.

Jinjing adopts an international advanced frequency conversion module, a special motor with speed up and down characteristics, and a set of PID parameters especially suitable for screw compressors. The control software has been tested by hundreds of thousands of compressors, with simple parameter settings and a friendly man-machine interface. The cooling of the frequency converter is specially designed. In order to support the user to set the best working pressure, the filtering area of the filter element of the oil-gas separator is increased.
