Screw compressor

GEA Grasso L XHP

Screw compressor optimized for ammonia heat pumps up to +95°C / 203 °F and 70-bar / 1,016-psi gas applications.

The GEA Grasso L XHP screw compressor is ideally suited for heat pumps. Based on the tried-and-trusted GEA Grasso screw compressor technology that has been refined over the last 50 years, the optimized design lends itself to a wide range of applications. As a result, we have extended the operation limits so that the GEA Grasso L XHP features a design pressure of 70 bar / 1,016 psi and a maximum discharge temperature of 140°C / 284°F. That means it is also a perfect fit for high-pressure gas applications. The compressor series is available in three sizes with a swept volume of 1,990 to 2,748 m³/h / 1,172 to 1,617 cfm at a running speed of 2,940 rpm.

Innovative high-pressure screw compressor

To ensure that the L XHP delivers the efficiency and reliability expected of a sustainable solution, we engineered an innovative new rotor profile. When combined with the extremely robust design and new balance piston concept, it makes the GEA Grasso L XHP the best high-pressure screw compressor we have ever created. It’s perfect for ammonia heat pumps and high-pressure gas applications.
