ZW-1.0/16-24 Liquefied Gas Compressor for Ammonia and LPG Applications
The ZW-1.0/16-24 Liquefied Gas Compressor is a reciprocating piston compressor developed for the transfer and recovery of low-boiling volatile gases.
Designed for liquefied gas applications, this compressor is suitable for ammonia, propane, butane, butene, and similar gas media. It is commonly used in gas delivery, storage transfer, loading and unloading, pressure boosting, and residual gas recovery processes.
The compressor provides a flow capacity of 1.0 m³/min, with an inlet pressure of 1.6 MPa.G and a discharge pressure of 2.4 MPa.G. Equipped with an 18.5kW motor, it offers stable compression performance for industrial gas handling systems.
With a compact structure of approximately 1300 × 800 × 1050 mm and a weight of around 500 kg, the ZW-1.0/16-24 is suitable for projects requiring convenient installation and efficient equipment layout.

Working Principle
The ZW-1.0/16-24 operates through a reciprocating piston compression cycle.
During the suction process, the piston movement creates a pressure difference, allowing liquefied gas vapor to enter the cylinder.
During compression, the piston reduces the cylinder volume and increases the gas pressure.
After reaching the required pressure, the compressed gas is discharged through the outlet valve and transferred to the downstream system.
This repeated cycle enables continuous gas delivery and pressure control for liquefied gas applications.
