Service Valves, type HRS, HRSB und HRSN
GEA service valves and GEA Needle Valves are designed to attach additional devices such as manometers to heating and refrigeration systems. Therefore they are available with various types of connections. They have a locking function that can be operated with a handwheel or a ratchet. With valve types HRS and HRSN, the stem is sealed by means of a screw bush. With valve type HRSB, the stem sealing is provided by a threaded bush and a metal bellows for completely hermetic sealing. The valves are also equipped with a back seal. When the valve is fully open, it is possible to replace the threaded bush and the seal without interrupting operation.

The GEA Ammonia Dryer removes water from the refrigerant cycle and makes the perfect addition to ammonia refrigeration systems along with filters and purgers.

PR-OLEO® ammonia oils are the natural choice to optimize industrial cooling and heating applications operating with reciprocating or screw compressors.
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.
Thanks to a new SmartParc manufacturing site, food processors in the U.K. are cutting their running costs and emissions. With GEA heating and cooling technology at its core, this collaborative production model demonstrates how innovation is accelerating the industry’s net-zero ambitions.
“Brewing eggs is like brewing beer.” It’s the kind of comparison that makes you smile – and then it clicks: Something complex suddenly feels simple. Through this personal film, set in the agricultural heartland of the U.S., we explore precision fermentation and the real-world work it takes to turn an idea into food.
