The ZW-3.0 / 16-24 Liquefied Gas Compressor is a premium industrial equipment designed by Bengbu United Compressor, a leading manufacturer in China. Engineered for efficiency and reliability, this compressor is tailored to handle liquefied gas (LPG) and similar low-boiling, volatile substances, making it a cornerstone for industries requiring safe and efficient gas handling.
At its core, the ZW-3.0 / 16-24 boasts impressive specifications: a processing capacity of 3.0m³/min, ensuring rapid handling of liquefied gas. It operates with an inlet pressure of 1.6MPa.G and an inlet temperature of ≤40℃, while delivering an exhaust pressure of 2.4MPa.G—ideal for applications needing consistent pressure control. Powered by a 55kW main motor, it balances power and energy efficiency, with an overall dimension of ~2500 × 1600 × 1850mm and a weight of ~2500KG, making it compact enough for diverse installation environments.
This compressor excels in critical operations such as LPG loading/unloading, tank transfer, residual gas/liquid recovery, and canning. It is widely used in LPG storage and distribution stations, mixing plants, gasification stations, canning factories, and automobile refueling stations. Beyond LPG, it efficiently handles propane, butane, butene, and even variant models support propylene and liquid ammonia, making it a versatile choice for multiple industrial needs.
The ZW-3.0 / 16-24 Liquefied Gas Compressor is built for peak performance. Its advanced design ensures high efficiency, reducing energy consumption while maintaining consistent output. With a focus on reliability, it minimizes downtime, a critical factor for industrial operations where interruptions can lead to significant losses. The integration of automated systems enhances operational precision, allowing for seamless monitoring and control—ideal for both manual and semi-automated workflows.
Designed with durability in mind, this compressor features fewer vulnerable parts, lowering the frequency of replacements and repairs. Its low vibration and noise levels create a safer, more comfortable working environment, complying with industrial noise standards. Routine maintenance is simplified: accessible components and clear service points mean technicians can perform checks and upkeep quickly, reducing operational disruptions.
The ZW-3.0 / 16-24 adopts a skid-mounted design, where all main and auxiliary equipment are integrated onto a single skid. This integrated structure ensures stable operation and simplifies transportation—whether by sea, air, or land. Installation is hassle-free, with options for fixed, mobile, or cabin-type setups, adapting to on-site conditions such as space constraints or the need for mobility.

Whole Machine Description
The compressor adopts D-type (symmetrical balance type), water-cooled, oil-free lubrication, reciprocating piston type, 2-row 3-stage compression, and the entire unit is supplied in a modular manner.
The compressor crankcase is made of gray cast iron and has four holes of different diameters for installing crosshead slides, bearings, and bearing seats. The lower part of the crankcase can store lubricating oil for the compressor to lubricate; The upper surface of the crankcase has an interface for installing a fuel inlet (breathing port) cover plate; In addition, the crankcase also has spare interfaces such as oil drain port, oil gauge observation port, bearing seat oil injection port, and installation oil temperature measurement port. The oil drain port of the crankcase has been connected to the outside of the compartment and is equipped with a manual ball valve for oil discharge from the crankcase.
The middle body of the compressor is a double middle body structure, ensuring that the middle body space is greater than one stroke, preventing compressor oil from entering the cylinder from the crankcase, thus ensuring that compressor oil does not contaminate the medium. The material of the compressor cylinder is gray cast iron/forged steel, and it adopts an oil-free lubrication design, which does not require oil lubrication. The cylinder head material is gray cast iron/forged steel, and the air valves are arranged axially on the cylinder head.
