Hybrid Vacuum Systems
Hybrid vacuum systems are formed by combining ejectors, surface condensers and / or liquid ring vacuum pumps. They consist of a combination of steam ejectors operating in series, followed by a condenser where the vapors are condensed and thereby reduces the load of vapours to be removed by the vacuum pump which compresses non-condensable gases to atmospheric pressure. Thay can be designed and manufactured according to the desired vacuum range, gas composition and availability of water and steam.
The main advantages of this type of vacum groups are the following:
- High vacuum and low consumption of steam, water and energy due to the combination of systems.
- Shorter start-up time of the system without the need for a start-up ejector.
- Possibility of condensate drain in a condenser previously installed.
- Low maintenance costs.
These systems can use barometric condensers or surface condensers, either vertically or horizontally.
