Enhanced performance with GEA Grasso V HS
GEA’s industrial reciprocating compressors are renowned for delivering a reduced Total Cost of Ownership (TCO) through lower power consumption and exceptional reliability. This proven concept is now available with an extended speed range – offering higher refrigeration capacity with a lower capital investment.
By increasing compressor speed, customers benefit from a significant boost in capacity. Due to the proportional relationship between speed, swept volume, and output, it is now possible to achieve up to 25% more capacity using the same compressor models. This translates directly into a lower relative cost per kilowatt.
For users with fixed capacity requirements, the increased speed enables the use of smaller compressor units, reducing both investment and service costs. Higher-speed operation also means a smaller installation footprint and reduced CO2 emissions – resulting in substantial savings and sustainability benefits across the lifecycle of the equipment.
Key features and highlights
- High-speed models up to 1,800 rpm for increased capacity and reduced investment costs
- Smaller footprint by using compact compressors at higher speeds
- Environmentally friendly: Zero GWP (Global Warming Potential) through the exclusive use of natural refrigerant NH3 (ammonia)
- One-piece welded compressor housing ensuring excellent temperature separation
- Extended and flexible maintenance intervals enabled by real-time condition monitoring, up to 22,500 operating hours
- Advanced bearing technology designed for a long service life
- Optimized suction and discharge valve design for high reliability and extended operational life
- Available as a packaged unit
