STELION Gas Cooler is a compact gas cooling system designed to reduce and control gas temperature in high-pressure applications, including hydrogen and other compatible gases. Developed for use after compression and in processes where gas temperature must be managed before the next stage, it provides a simple cooling solution for compression, testing, storage and refueling environments.
Designed to complement STELION Booster Station and other gas systems, STELION Gas Cooler brings high-pressure gas cooling into a compact, easy-to-integrate format.
Compression and cooling. One complete workflow
Combine STELION Gas Cooler with the STELION Gas Booster Pump to create an integrated solution for high-pressure gas compression and downstream cooling. STELION Booster Station increases gas pressure, while STELION Gas Cooler manages the temperature of hydrogen and other compatible gases after compression.
Together, both systems provide a compact and flexible compression and cooling solution for laboratories, testing facilities, refueling applications and field operations.
Control gas temperature after compression
Gas temperature can increase significantly during compression. STELION Gas Cooler is installed downstream of the compression stage to remove this excess heat before the gas continues to storage, testing, refueling or another process.
The gas passes through the cooling system, where heat is transferred away to reduce its temperature according to the operating requirements of the application.
For hydrogen applications, STELION Gas Cooler acts as a compact hydrogen cooling system or hydrogen aftercooler downstream of the compressor.
The result is a controlled cooling stage that can be integrated directly into the system workflow

Know the essentials
STELION Gas Cooler is a compact high-pressure gas cooling system designed to reduce and control gas temperature in applications where thermal management is required. It is particularly suited to hydrogen applications and can also be configured for other compatible gases.
Compressing hydrogen generates heat and increases the gas temperature. Depending on the downstream equipment or process, this temperature may need to be reduced before the hydrogen can be stored, tested, transferred or dispensed.
A hydrogen gas cooler or hydrogen aftercooler removes this excess heat downstream of the compression stage.
A hydrogen cooling system removes the heat generated during hydrogen compression before the gas continues to storage, testing, refueling or another downstream process.
The compressed hydrogen passes through a heat exchanger where thermal energy is transferred to a cooling circuit, reducing the hydrogen temperature to the level required by the application. This process is commonly referred to as post-compression cooling or aftercooling.
Not every gas boosting application requires downstream cooling. However, gas temperature increases during compression, and some storage, testing, refueling or industrial processes require the compressed gas to be cooled before the next stage.
A gas cooling system installed after a gas booster pump can remove this heat and control the outlet temperature according to the requirements of the application. STELION Gas Cooler can be integrated downstream of STELION Booster Station or other compatible gas booster pumps.
A gas booster pump increases gas pressure through compression. During this process, part of the compression energy is converted into heat, increasing the gas temperature at the outlet.
The temperature rise depends on factors such as the gas, inlet and outlet pressures, compression ratio, flow rate and booster technology. When the downstream process requires a controlled temperature, a gas cooler or aftercooler can be installed after the booster pump.
Compressing hydrogen generates heat and increases the gas temperature. STELION Gas Cooler is designed for high-pressure applications with operating pressures of up to 700 bar. The final configuration depends on gas type, pressure, flow rate and thermal requirements.
Yes. STELION Gas Cooler has been developed primarily as a Hydrogen Cooling System, but its cooling architecture is not limited to hydrogen. It can be adapted for a wide range of gases and fluids, making it suitable for laboratory, industrial, testing and high-pressure thermal management applications.
The final configuration is defined according to the properties of the gas or fluid, operating pressure, inlet and target temperatures, flow rate and cooling requirements of each application.
Yes. STELION Gas Cooler is designed to complement STELION Booster Station whenever cooling is required downstream of the compression process. It can also be integrated downstream of other compatible gas booster pumps, depending on the operating conditions of the application.
The system is intended for applications requiring controlled gas temperature, including hydrogen compression systems, laboratory and R&D installations, testing equipment, storage processes, refueling systems and other industrial gas applications.
Yes. STELION Gas Cooler can be considered for integration into different gas compression and handling systems. Compatibility depends on gas type, operating pressure, flow rate, inlet temperature and required outlet temperature, so each application should be evaluated individually.
