The new STELION Gas Cooler is a compact gas cooling unit designed to reduce hydrogen temperature after compression. The unit provides a cooling stage before storage, testing, refuelling or other processes that require gas temperature conditioning. Developed primarily for hydrogen, the STELION Gas Cooler can be integrated with the STELION Booster Station and other compatible compression systems. It provides a dedicated cooling stage within the installation, tailored to the requirements of the downstream process. The STELION Gas Cooler is connected in series between the compressor and the end-use application. It receives gas after the compression stage and cools it before directing it to the process where it is needed. Applications include R&D laboratories, test benches, gas storage processes and hydrogen refuelling systems, including those used for drones. The unit uses electrically powered Peltier thermoelectric technology and is designed to operate at pressures of up to 700 bar. Its suitability for each application also depends on the flow rate and the required inlet and outlet temperatures. In a test conducted at Hydros Power’s facilities at 700 bar, temperatures of 50°C at the compressor outlet and 15 °C at the STELION Gas Cooler outlet were recorded. These results reflect specific test conditions, and thermal performance may vary depending on ambient and operating conditions. In addition to hydrogen, the STELION Gas Cooler can be adapted for other compatible gases and fluids, depending on the application requirements. Its compact format allows rack mounting and layout adjustments to suit the available space. The power supply can be repositioned on either side of the unit, allowing users to adapt the layout as the arrangement of other components in the installation changes. The unit measures 386 × 272 × 335 mm and weighs 18.3 kg. Depending on the configuration, it features quick couplings or 1/4-in. male NPT connections for connection to the compression system and the line carrying cooled gas to the end-use application. — Hydros Power, Madrid, Spain
