Skid Mounted Compressor

 

We aim to develop tailored equipment packages for fixed and skid-mounted hydrogen refueling stations, tailored to meet the diverse needs of our customers.

Firstly, our fixed hydrogen refueling stations are equipped with unloading, pressurization, storage, and cooling units designed for remote dispensing. We also offer monitoring of key equipment status, along with cloud computing and big data analysis capabilities, ensuring a higher efficiency and utilization rate.

Secondly, our skid-mounted hydrogen refueling stations integrate hydrogen refueling, cooling, metering, and digital control. With the equipment manufacturing, testing, and commissioning processes completed in the factory, these stations can be easily and efficiently installed within a short period.

Lastly, both our fixed and skid-mounted hydrogen refueling stations are available for customization and assembly based on customers' specific requirements. They are also compatible with diaphragm or liquid-driven compressors, providing flexibility and adaptability to meet a wide range of applications.

 

 

1. Liquid driven compressor

Powerful displacement: The excellent performance of this compressor is reflected in its powerful displacement, reaching 1000Nm³/H@12.5MPa provides sufficient power support for the hydrogenation process.
High pressure output: The exhaust pressure can reach up to 45MPa, making it excellent in high-pressure processes such as hydrogenation, ensuring efficient and stable operation of the production process.
Wide range adaptability: The inlet pressure range is wide, from 2MPa to 20MPa, which can be applied to different working conditions and has excellent flexibility.
Excellent temperature control: The maximum exhaust temperature does not exceed 120 ℃, and after cooling, the exhaust temperature is even lower than 40 ℃, effectively ensuring the stability of the equipment during long-term operation.

Equipment reliability

• Long sealing life: The equipment adopts advanced sealing technology to ensure a sealing life of over 2000 hours, greatly reducing maintenance frequency and production downtime, and improving the overall reliability of the equipment.
• Efficient motor drive: The main motor power is 110kW, providing strong driving force for equipment, ensuring efficient and stable operation, and reducing energy consumption costs.
• Low noise design: The equipment noise is controlled below 80dB (A), taking into account the high sensitivity of modern industrial environments to noise, ensuring a safe working environment for operators.

Parameter	≥1000Nm³/h@12.5MPa	45MPa	2~20MPa	≤120℃	≤40℃	≥2000h	110kW	≤80dB(A)

 

2. Compressor skids

Module-based design: Modules are separated for the hydraulic system, compression system, heat exchange system, and pipeline system in the structure for easy operation and maintenance.

Safety and reliability: The electrical components within skids are explosion-proof with a reliable electrostatic grounding system. Full-lift safety valves are used to prevent the equipment from overpressure. A gas detector is inserted in the skids which are connected to the ESD system of the compressor to automatically shut down and cut off the gas inlet in an emergency.

Highly automatic design: The PLC fully automatic control system is adopted for the control of the compressor. The control panel can show and check the operating status of the compressor with alarm and automatic diagnosis features. One-click start, fault warning/diagnosis and other features are available.

Full water-cooling system: It supports more efficient heat exchange, lower exhaust temperature, and lower operating temperature.

The explosion-proof certification has been attained for the entire equipment as required by the regulations of the region where the user is located.

Parameter	45MPa	1000Kg/day	-25-55℃

 

3. Hydrogen dispenser

Fully automatic control: one-click operation available for hydrogen refueling with leakage detection, alarm and shutdown features. When it comes to the set pressure of 35 MPa/70 MPa during refueling, it stops automatically to maintain safety at the underlying level.

Wide flow range: The flow range of the hydrogen dispenser is 0-5.0 kg/min, which can meet the demand for hydrogen refueling in different applications from small-scale in laboratories to large-scale use in industrial cases.

High-precision measurement: The measurement fault of only ±1.5% and the measurement repeatability of up to 0.5% ensure the accurate measurement and pricing of hydrogen refueling.

Safety and explosion-proof design: The explosion-proof level of the equipment is certified as Ex d e ib mb llC T4Gb, which ensures that the equipment can run in a safe and stable environment as a trustworthy safety guarantee for the refueling process.

4. Sequence control panel

Module-based design: The overall pipeline structure is module-based, which is easy for staff to repair and maintain.

Efficient program control design: Automatic refueling/storage are available with multiple nozzles to refuel the hydrogen-fueled vehicles at the same time.

Safe and reliable design: The hydrogen pipes are connected by Autoclave fittings (C&T fittings) or NPT fittings. Electrical components meet the explosion-proof requirements.

Adaptable to various conditions: The sequence control panel can work well under various environmental conditions, of which the operating temperature ranges from -40°C to 50°C, making it adaptable to various operating conditions.

Name	Applicable medium	Operating pressure	Design pressure	Environment temperature	Rating
Parameter	H2	45MPa	50MPa	-40°C~50°C	III

 

5. Discharging column

Sophisticated pipeline design: The entire pipeline is arranged following a clear flow process made up of primary and secondary sections. The primary section (for hydrogen) and secondary section (for nitrogen purging used in the replacement reactions) are easy to identify, which can effectively improve the accuracy and safety of operations and reduce misoperation.

Safe and reliable design: The gas for instruments and purging are isolated. Full-lift safety valves are used. The pipeline is designed with an automatic leak detection feature.

Precise measurement repeatability: The measurement repeatability of the discharging column is 0.5%. Precise measurement control ensures accurate and stable discharging.

High filtration precision: High-efficiency filters of 5μm can remove other impurities from hydrogen and improve the purity of hydrogen.
