Low Refrigerant Charge and Improved Safety Concept
Reduced Installation Effort and Cost
The packaged design minimizes field-installed ammonia piping and electrical work, resulting in a streamlined installation process and shorter commissioning times compared to traditional central refrigeration systems. The compact skid-mounted arrangement further simplifies installation while reducing overall project costs.
High Efficiency Across Full and Part Load
Featuring variable internal volume ratio (Vi) and optional variable frequency drive operation, the compressor delivers high energy efficiency across a wide operating range. This provides excellent Energy Efficiency Ratio (EER) performance under design conditions while maintaining strong part-load efficiency to reduce operating costs.
Reliable Operation and GEA Omni Control
The chiller's rebuildable screw compressor, industrial-grade components, and service-friendly layout help maximize equipment life while minimizing downtime and lifecycle costs. The GEA Omni control system provides intuitive operation, advanced monitoring, remote access, and optional automatic chiller sequencing for optimized plant operation. A wide range of options allows it to be tailored to specific application requirements and site conditions.

GEA Insights
The water equation
Across Europe, drought is a recurring reality – and no longer confined to the south. While water increasingly shapes where industries locate, its value is determined by local context. There are many technological routes to water efficiency in industrial processes, but location, energy needs and other factors are also key.
