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 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.
Beyond the machine: unlocking better plant performance
An efficient machine does not automatically make an efficient factory. Real improvement often starts by looking beyond individual equipment and understanding how processes, energy systems and operating decisions affect one another. It’s a holistic approach designed to uncover opportunities that might otherwise be missed.
How a valve reshapes the way food and drinks are made
In food and beverage plants, valves are commonly operated using compressed air. GEA Hydract® Actuation Technology moves valves with water instead, in a closed, digitally controlled circuit. The result is a valve that can be held exactly in place and steered in fine-tuned steps. This results in lower energy use and greater control.
