Engineered to meet the demands of various industrial applications, this compressor stands out for its efficiency, reliability, and adaptability to custom requirements.
At its core, the DW-9.55 / 0.03-16 Hydrogen Compressor operates with hydrogen gas (100 mol% medium composition) and delivers exceptional performance metrics: a flow rate of 515Nm³/h, inlet pressure of 0.003MPa.G, exhaust pressure of 1.6MPa.G, and a main motor power of 90kW. Its compact design, with overall dimensions of approximately 5000 × 3200 × 2100 mm and a weight of ~8T, ensures easy integration into diverse operational environments.
Ideal for hydrogen power generation, energy storage, fuel cell vehicle systems, and industrial heating, this compressor plays a critical role in compressing hydrogen to required pressures for storage, transportation, or direct use. Beyond standard specifications, Bengbu United Compressor offers tailored solutions, adapting to specific client needs such as flow rate, purity, pressure, and operational conditions—from design to production.
The DW-9.55 / 0.03-16 Hydrogen Compressor is built for maximum efficiency, with a focus on reducing energy consumption and maintenance needs. Its advanced design minimizes vulnerable parts, resulting in low vibration and noise levels, making it easy to operate and maintain. The 90kW main motor ensures consistent power output while optimizing energy use, aligning with sustainability goals for hydrogen-related industries.
Recognizing that industrial needs vary, the DW-9.55 / 0.03-16 Hydrogen Compressor supports extensive non-standard customization. Clients can choose from multiple structural forms (D-type, M-type, S-type, W-type, V-type, Z-type), cooling methods (water-cooled, air-cooled, mixed cooling), and installation types (fixed, mobile, skid-mounted, cabin-type). Drive modes include motor or diesel engine, ensuring compatibility with diverse operational setups.
This compressor features a 2-row reciprocating piston structure with a single-layer arrangement (crankcase center height: 315mm) and horizontally arranged, single-acting cylinders with a double-stage difference (first & fourth stages, second & third stages). Key components like oil scrapers, intermediate seals, and cylinder pressure packings use stainless steel clamping spring split rings, enhancing durability and preventing hydrogen leakage. The pressure packing box is equipped with an inflation system and leakage collection pipes (stainless steel) to ensure safety and environmental compliance.
The DW-9.55 / 0.03-16 Hydrogen Compressor is widely applicable in hydrogen power generation, energy storage (high-pressure tank storage), fuel cell vehicle refueling, and industrial heating systems. Its ability to handle inlet temperatures ≤ 40℃ and deliver 1.6MPa.G exhaust pressure makes it suitable for both small-scale and large-scale operations, from on-site hydrogen compression to long-distance storage solutions.
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.
