Geothermal compressors are core power equipment for geothermal power generation, geothermal heating, circulation and reinjection of geothermal fluids (water/steam/CO₂), as well as the development of geothermal associated gas and hot dry rock resources. Their key functions include pressurizing and conveying geothermal media, improving energy conversion efficiency, and ensuring closed-loop stable operation of geothermal systems. They are essential equipment for the large-scale development of geothermal energy.
