Vacuum systems with surface condensers for non-barometric installation
Contrary to a barometric installation of surface condensers (barometric height 11 m), this set-up offers the possibility of reducing the system's installation height. This design, using vertical surface condenser, is used in cases where there is a liability of a higher degree of pollution by the process flows. The installation of spray nozzles in the condenser head enables "cleaning" to take place even during operation. Horizontal installation - see option with liquid ring pump.
Advantages at a glance
- Reduced installation height
- Separation of the process- and cooling water flows
- Short start-up time without a start-up ejector
- Possibility of draining condensate from the pre-connected
Disadvantages
- Possibility of pollution on the process- and cooling water side
- Increased maintenance and repairs expenditure (mechanical pump)
- Increased liability towards breakdowns
- Possibility of material damages due to cavitation (mechanical pump
- Limited possibilities in the choice of materials (mechanical pump)
