The various ammonia and petroleum gas compressors produced by our company are all oil-free reciprocating piston type. The cylinder and packing parts of the compressor are all without oil lubrication to ensure the purity of the working medium. The crankshaft, connecting rod and crosshead parts are pressure lubricated to ensure the reliability of lubrication.

ZW and ZG series compressors are vertical, air-cooled, single-acting non-lubricated reciprocating piston type, DW/2DG series compressors are symmetrical and balanced (the first and second stages of reciprocating inertia and centrifugal force are fully balanced), moment of inertia, centrifugal force Features such as small moments.

VW series ammonia compressor, oil-free, piston type, with low vibration, low noise, balanced operation, compact structure, large displacement, convenient operation, safe and reliable, etc.

Lubrication method: 1. Pressure type 2. Splash type (choose according to actual needs)

Product structure: 1. Vertical horizontal bar 2. Vertical parallel bar 3. Symmetrical balanced type (choose according to actual needs)

And according to user requirements, provide mobile, fixed, and car-mounted.

Product use: Mainly used for process gas unloading, loading, refilling, residual gas recovery and residual liquid recovery process system. It can also be used for the loading and unloading and storage of ammonia, freon, ethane, ethylene, propane, propylene, butene, dimethyl ether, difluoroethane and other substances.
