Thanks to advanced engineering design and less component complexity, GEA Grasso M screw compressor units combine outstanding reliability and easy servicing with high efficiency. These features offer excellent savings potential on energy, service and other operating expenses and lower the total cost of the refrigeration system over its entire life cycle.

Save energy, service and operating expenses – Lower your total cost of ownership

Engineered for energy efficiency, GEA Grasso M screw compressors consume 3 to 5 % less power than their predecessors. This adds up to significant savings on your electricity bill! GEA Grasso M units operate without an oil pump – which further reduces energy consumption and lowers spare partcost.

Powered by high speed motors (variable speed range: 1,000 – 4,500 rpm), GEA Grasso M units deliver top capacities and maximum efficiency for low part-load requirements.

To save space, the screw compressor and driveline are mounted on top of the horizontal oil separator. This state-of-the-art vessel separates the oil from the refrigerant most effectively. Minimal oil carry-over (5 ppm) and oil charges benefit your total cost of ownership by lowering utility and maintenance costs.

Rely on GEA Grasso M compressor units to redefine your total cost of ownership and reduce life-cycle expenses.
