Screw Compressors
The GEA Grasso LT series comes in sixteen sizes and covers a swept volume from 805 to 11,467 m3/h (at 2,940 rpm).
The compressor has an extremely long life span and low noise and vibration levels due to the combined sleeve and roller bearing of the rotors. All components are designed for long operating life, high availability and easy maintenance. GEA screw compressors can be provided according to the API 619 standard and ISO 10440.

GEA's innovative process marks a milestone in the pretreatment of biofuels such as hydro-treated vegetable oil and sustainable aviation fuel. By eliminating the bleaching process, manufacturers benefit from significant savings potential: over 50% lower operating costs and up to 12% less CO2 emissions.
Climate change and a growing world population put increased pressure on the energy-intensive food industry to feed more people without further impacting the planet. George Shepherd, GEA’s Global Technical Sustainability Manager, explains how GEA uses its engineering know-how to help processors produce more sustainably yet increase productivity.
