Vacuum Technology
Steam jet cooling systems are based on proven jet pump technology and often used to cool a liquid directly without any additional refrigerant by means of flashing into the vacuum.
The vacuum cooling plants represent a specialty among the jet pump systems. Vacuum cooling plants are used to cool a liquid directly without any additional refrigerant by means of flashing into the vacuum.
GEA designs and manufactures plants for the cooling of acids, lye, suspensions and liquid food.
Cooling is an expensive process. Ongoing increases in energy costs demand alternatives to traditional systems (mechanical compressors). More and more, flash cooling plants offer an environmentally friendly and economical solution.
GEA has more than fifty years of experience in the design and construction of flash cooling plants.
For each type of fluid the evaporation pressure requires a particular evaporation temperature. A liquid will start to boil if it is subjected to a pressure that is lower than its evaporation pressure. In flash cooling plants, only a small proportion of the medium to be cooled is evaporated (vapor flow [kg/s]). The thermal energy required for this process is taken from the remaining medium: its temperature drops until the boiling temperature to the lower pressure has been reached.
The vapor flow conveys the thermal energy from the cooled medium into a condenser thereby transferring the thermal energy to another system (heat consumer, re-cooling system etc.).
Basically, there are three different types of steam jet cooling plants:

Combined Steam Jet and LRVP Systems are based on proven jet pump technology and often used to create and maintain the vacuum.
With state-of-the-art pilot plants and test benches our R & D Center is optimally equipped for testing in the fields of jet pumps and vacuum systems.
Multi-stage steam jet vacuum pumps are used to produce vacuum in evaporators, driers, distillation plants, rectifying, freeze drying, poly-condensation, degassing, deodorizing plants etc.
Resource-efficient fashion has been a long-sought ambition amid the fashion industry’s considerable contributions to global carbon emissions. The need to close the loop by recycling textile fibers into virgin-like materials is higher than ever but seemed like a distant dream until now: Circ, GEA’s American customer and pioneer in the field of textile recycling, might be rewriting the future of the fashion industry.
Alternative proteins are promising – yet still expensive to produce. The usual response is that scaling up will solve this issue. But what if the solution was really about getting better, not just bigger? From more efficient, high-yield processes to upcycling waste heat, engineers are reshaping how we grow food.
As anti-cancer drugs become more powerful and complex, GEA is redefining how to safely freeze-dry these life-saving treatments.
