The DW-1.6/(8~12)-120 Hydrogen Compressor is a high-performance reciprocating piston compressor specifically designed for efficient and reliable hydrogen compression. It is well-suited for a variety of industrial applications, including hydrogen refueling infrastructure, chemical process hydrogen boosting, high-pressure hydrogen storage systems, and industrial gas supply scenarios, ensuring stable operation even in demanding working environments.
Key technical parameters define its performance capabilities: it uses hydrogen as the compression medium, with a processing capacity of 740~1000 Nm³/h (meeting 800 Nm³/h at 0.85 MPa as the design point). The inlet pressure ranges from 0.8 to 1.2 MPa.G (with inlet temperature at ambient temperature), and the exhaust pressure reaches 12 MPa.G. Powered by a 160 kW main motor (model: YBBP-355M1-6), the compressor has an overall dimension of approximately 5800×3000×2300 mm and a total weight of around 8.5 T. Its skid-mounted design allows for easy installation and integration into existing industrial layouts.
This compressor is part of a specialized product lineup focused on hydrogen handling. While it is tailored for the flow range of 740~1000 Nm³/h and high exhaust pressure of 12 MPa.G, the core design concepts can be adapted to meet custom requirements—covering different flow rates and pressure levels—to cater to diverse industrial needs, from petrochemical hydrogen recovery to new energy hydrogen application projects.
The DW-1.6/(8~12)-120 Hydrogen Compressor boasts excellent stability and durability, supported by meticulous structural design. It adopts a D-type (symmetrical balanced) structure with two rows and four stages of compression, which effectively reduces mechanical vibration (complying with the GB/T7777-2021 standard) and noise (meeting the GB/T4980-2003 requirement). The open water-cooling system cools the cylinders, packing, and compressed medium, ensuring stable operation even during long-term continuous work. Key components, such as the 45# forged crankshaft (with induction-hardened crankpins) and 42CrMo piston rod (with nitrided surface and a minimum hardness of HRC60), significantly extend the equipment's service life.
A core advantage of this compressor is its oil-free lubrication design, which is crucial for maintaining hydrogen purity. It features a double-middle-body structure, where the middle-body space exceeds one stroke, preventing crankcase oil from entering the cylinders and contaminating the hydrogen medium. The cylinders (first and second stages: ductile cast iron; third and fourth stages: forgings) and packing (special polytetrafluoroethylene-filled materials) adopt an oil-free design, eliminating the need for oil injection lubrication. This ensures the compressed hydrogen meets high-purity requirements, making the compressor suitable for applications like fuel cells where medium contamination is strictly prohibited.
The compressor is equipped with a sophisticated control system for intelligent and safe operation. The unit control cabinet integrates a Siemens Smart-200 PLC and a 7-inch Weinview color touchscreen, supporting frequency conversion startup to avoid impact on the motor. It reserves an RS485 communication interface (using the MODBUS-RTU protocol) for connection to the user's DCS system, enabling unattended operation. In addition, the compressor provides comprehensive safety protection: it conducts real-time monitoring and offers alarm/shutdown protection for motor overload/short circuit, lubricating oil pressure, cooling water pressure, inlet pressure, multi-stage exhaust pressure, and multi-stage exhaust temperature, ensuring safe and reliable operation.
Application Area
Hydrogen compressors are essential in the hydrogen industry chain. With its 12 MPa.G high exhaust pressure and oil-free lubrication design, the DW-1.6/(8~12)-120 Hydrogen Compressor plays a key role in multiple scenarios. In high-pressure hydrogen storage, it compresses hydrogen to 12 MPa.G for storage in high-pressure vessels, supporting emergency gas supply and peak shaving in industrial systems. In chemical processes, it boosts low-pressure hydrogen (0.8~1.2 MPa.G) to the high pressure required for reactions, such as in hydrogenation processes. In the new energy field, it can be used in supporting facilities of hydrogen refueling stations, providing a stable high-pressure hydrogen source for fuel cell vehicles (after matching with subsequent pressure regulation systems). Its skid-mounted integration and strict compliance with explosion-proof standards (motor explosion-proof grade: ExdIICT4) also make it suitable for hazardous industrial environments that require safe hydrogen handling.
