Vacuum Systems with Vertical Surface Condensers and
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.

Advatages:

• 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)
