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
The breakthrough that changed spray drying
In 1976, NIRO engineers responded to a competitive challenge by rethinking what spray drying could do. Their idea became the multi-stage dryer MSD. Fifty years later, the same fundamental principle helps turn liquids into the powders used in essential nutrition products and important medicines around the world. Refined through decades of engineering expertise, customer insight and continuous development, MSD is a story of innovation with lasting impact.
