Applications
Steam jet compressors are used in evaporating, distillation, cooling, crystallization, deodorization, degassing and drying under vacuum.
In the positive pressure range the compressed exhaust vapors are used for heating (heat pump).
Mode of operation
Their operation is based on the liquid jet emerging from the motive nozzle hitting and entraining the surrounding gases and compressing them to a higher pressure (see also “Product catalogue”).
Advantages
- Large vapor volumes, particularly in high vacuum ranges, are easily handled
- Low investment cost due to the relatively simple construction
- Long operational life expectancy as steam jet compressors can always be
- Constructed of a suitable corrosion resistant material
- High operational safety and low maintenance as no moving parts are involved
In relation to these advantages, the efficiency does not play significant role, compared to other compressors. As a result of it being custom built for a duty, with correct design and application a high operating efficiency can be achieved.

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.
