Overview


ZW-1.46/(1-14.2)-(4-17.2) Liquefied Gas Compressor for Propane and LPG Transfer

The ZW-1.46/(1-14.2)-(4-17.2) Liquefied Gas Compressor is a Z-type reciprocating piston compressor designed for the compression and transfer of low-boiling volatile gases.

The compressor is suitable for liquefied gas media including propane, butane, butene, propylene, and liquid ammonia. It is mainly used in industrial gas systems where stable compression and controlled gas transfer are required.

With a flow capacity of 1.5 m³/min, the compressor operates with an inlet pressure range of 0.1–1.42 MPa(G) and a discharge pressure range of 0.4–1.72 MPa(G). The unit is driven by a 22 kW motor and adopts a water-cooled, oil-free reciprocating piston structure.

The skid-mounted configuration integrates the compressor system into a compact package, providing a practical solution for liquefied gas stations, chemical plants, and industrial gas handling applications.
