Vacuum Technology
Product Driven Steam Jet Vacuum Systems are based on proven jet pump technology and often used if the product vapor is used as the motive medium for the jet pumps or if it is essential that no water enters the system.

Jet vacuum systems are used to create and maintain the vacuum in production plants for Polyester and Nylon.
Jet vacuum pumps are generally driven by water vapor. Water vapor is easily obtained in industry and has proved itself as a good motive medium. When the motive steam in the jet vacuum pump condenses, condensate is produced which in some cases must be regarded as waste.
This can be avoided if the product vapor which is produced during the process, is used as the motive medium for the jet pumps. The motive steam condensate is then either put to further use in the process or is re-evaporated and is used again as the motive medium. Product vapor driven jet pumps are also used if it is essential that no water enters the system.
Product vapor driven jet vacuum pumps do not differ in their functioning from water vapor driven jet vacuum pumps and therefore offer the same fundamental advantages. In addition, the energy requirement is in part substantially lower than is the case with water vapor driven jet vacuum pumps because of the low evaporation heat of organic vapors.

Variable - Flow Ejectors are based on proven GEA jet pump technology and often used for heat recovery.

Steam jet ventilators are based on proven jet pump technology and often used to convey air, gases and vapors.

Steam jet compressors type bv1 are based on proven jet pump technology and often used used in evaporating, distillation, cooling, crystallization, deodorization, degassing and drying under vacuum.

For more than 100 years, GEA has developed technologies for dairy farming – from the first bucket milking machines to autonomous, digitally connected systems. These innovations have fundamentally transformed dairy farming: away from labor-intensive routines, toward greater productivity, animal welfare and more efficient day-to-day operations.
