The high-efficiency compression is achieved with a small high-speed centrifugal compressor, which features a dynamic pressure gas bearing that does not require lubricating oil, thereby enhancing the heat transfer efficiency of the heat exchanger. Compared to conventional scroll and screw types, both the volume and weight are reduced to 1/3 to 1/10, and since there are no sliding parts, the decrease in efficiency is minimized. For more details, please contact us. [Development Example] ■ 170,000 rpm centrifugal compressor *For more information, please refer to the external link or feel free to contact us.

The "cryogenic expansion turbine" is an expansion turbine that uses air, carbon dioxide, nitrogen, argon, helium, hydrocarbon-based refrigerants, etc., as the working fluid and can cool down to below -100°C. The rotating shaft contains permanent magnets, allowing it to function as a drive motor or generator. The unit shown in the photo has a compressor installed on the other end of the shaft. Because it uses a dynamic pressure gas bearing, it does not require lubricating oil or seals, enabling cooling to the allowable temperature of the medium. 【Features】 - The rotating shaft contains permanent magnets - Functions as a drive motor or generator - Does not require lubricating oil or seals, allowing cooling to the allowable temperature of the medium *For more details, please refer to the external link or feel free to contact us.

The "Geothermal and Waste Heat Recovery Turbine Generator" is a turbine that uses natural refrigerants such as ammonia, hydrocarbon fluids, and alternative refrigerants as working fluids, with a capacity range of 10-3000 kW. It incorporates dynamic pressure gas bearings and a permanent magnet high-speed generator. Since it does not use lubricating oil, it improves the performance of heat exchangers and prevents contamination, eliminating the need for seals on pumps, tanks, and coolers. [Development Examples] - Water/Ammonia: 50,000 rpm, 100 kW, outer diameter 400 mm, length 800 mm - Ammonia: 30,000 rpm, 50 kW - R245fa: 25,000 rpm, 30 kW *Please feel free to contact us for more details.
