The Spirotech Superior S16A-I: The Vacuum principle ensures that the systems Air content (inc dissolved oxygen) is constantly maintained at the lowest possible level, thus providing considerable system benefits;


• Lower capital outlay, reduced installation and ongoing maintenance costs.
• Permanent protection against oxygen based corrosion
• No cavitation of system pumps
• Reduction in system Pump energy as Air free system reduces resistance to flow
• Air free system permits accurate balancing of System.
• Wet balancing of system reduced to shortest possible time
• No requirement for further manual venting of the system

The proven principle of Deaerating refill water combined with Vacuum Degassing is the most effective form of maintaining air free LTHW & CHILLED Water systems
