GEA Grasso M 系列 – C/D/E/G 型号
GEA Grasso M 系列 – H/L/M/N 型号
GEA Grasso M 压缩机是首款螺杆压缩机，具有集成压力激活式止回阀，可以确保压降较低。
吸滤器与保护壳的集成极大地简化了整套产品的装配。这些压缩机出色的节能效果基于可无限调整的容量与扩展的可变 Vi 范围（内部容积比）。1,000 到 6,000 转/分钟的可变速度确保了操作范围广，在满载和部分负载中均能实现最高效率。

GEA 洞察
GEA reports profitable growth for 2025 and expects accelerated revenue growth
GEA’s past fiscal year was one of significant growth and further profitability gains. In particular, the technology group substantially increased order intake, with all divisions contributing here. GEA also made progress in all Mission 30 strategic growth areas. In addition, GEA met key interim targets under its climate plan ahead of schedule. Major milestones in fiscal year 2025 were admission to the DAX index, the award of one of the largest contracts in the company’s history, and streamlining of the corporate structure.
