GEA Grasso L XHP screw compressor: Ideally suited for heat pumps
October 8, 2024
At Chillventa 2024, GEA presented the GEA Grasso L XHP, a screw compressor with an 70-bar design that extends the operating limits of heating applications with ammonia to higher temperatures of up to + 95 °C. The screw compressor has a new optimized rotor profile which increases the efficiency and reliability. Combined with an extremely robust design and a newly designed balancing piston concept, the result is a high-pressure screw compressor that is ideal for ammonia heat pumps and high-pressure gas applications.

Optimized design of the screw compressor GEA Grasso L XHP for a wide range of applications
The L XHP is based on the proven technology of GEA's Grasso screw compressors, which have been continuously developed and improved for over 50 years. Thanks to its extended operating limits, the GEA Grasso L XHP is designed for a pressure of 70 bar and a maximum discharge temperature of 140 °C, making it ideal for high-pressure applications. The compressor series comprises three sizes with a swept volume of 1,990 to 2,748 m³/h at a speed of 2,940 rpm, which can be driven at up to 3,600 rpm. That leads to a heating capacity range of 2 to 11 MW per compressor.
