The DW-1.8/15-30 Hydrogen Compressor, manufactured by Bengbu United Compressor (a leading China-based compressor supplier), is a cutting-edge reciprocating piston compressor designed for efficient hydrogen compression. Tailored for diverse industrial applications, this compressor stands out with its robust performance and versatile design, making it ideal for hydrogen power generation, energy storage, fuel cell vehicles, and high-pressure hydrogen storage systems.
Key technical parameters define its capabilities: it handles a hydrogen gas medium with a processing capacity of 1500Nm³/h, operates at an inlet pressure of 1.5MPa.G (with inlet temperature ≤ 40℃), and achieves an exhaust pressure of 3.0MPa.G. Powered by a 75kW main motor, it features compact overall dimensions of 3200 × 3000 × 1850 mm and a total weight of 5.8T, ensuring easy integration into various industrial setups.
Beyond standalone performance, the DW-1.8/15-30 is part of a comprehensive product line that includes other hydrogen compressor models (such as DW, ZW, MW, PW, and VW series), covering flow rates from 150Nm³/h to 4500Nm³/h and exhaust pressures ranging from 0.65MPa.G to 20MPa.G. This range allows Bengbu United Compressor to meet custom requirements across industries, from oil & gas to renewable energy.
The DW-1.8/15-30 Hydrogen Compressor boasts high efficiency and strong reliability, backed by advanced engineering. Its D-type (symmetrical balance) structure minimizes vibration and noise, while a water-cooled system ensures stable operation even under prolonged use. With fewer vulnerable parts, it reduces downtime and maintenance costs, making it a cost-effective choice for long-term operations.
A critical advantage is its oil-free lubrication technology, achieved through a double middle body structure that prevents crankcase oil from contaminating the hydrogen medium. This design is vital for maintaining hydrogen purity—essential in applications like fuel cell systems where even minor oil contamination can damage equipment. The cylinder and cylinder head, made from gray cast iron/forged steel, further enhance durability and medium integrity.
Bengbu United Compressor integrates proprietary technologies, including patents such as ZL 2017 2 1907021.7 (piston rod thread protective sleeve) and ZL 2017 2 190177.0 (range piston for symmetrical balanced compressors). These innovations enhance structural stability, extend component lifespan, and ensure compliance with international quality standards.
Application Area
Hydrogen compressors play a crucial role in hydrogen power generation, energy storage, and heating. For example, compressing hydrogen gas to high pressure for fuel cell power generation, or storing it in high-pressure gas cylinders or underground storage tanks for emergency use. In addition, hydrogen heating systems also rely on their high-pressure delivery capacity. Hydrogen fuel cell vehicles rely on a hydrogen compressor to compress the hydrogen gas in the storage tank to the required pressure of the fuel cell, which is the core component of vehicle operation. Lightweight design and efficient compression technology are the focus of this field.

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.
