Air & Gas Eliminators

Air & Gas Eliminators

An accumulation of air and other non-condensible gases in pressurized liquid lines can cause a number of problems. These gases can lead to corrosion, excessive noise, reduced heat transfer, and eventually can impede or stop the liquid flow. It can cause air locks which inhibit the filling of the system or the priming of pumps. It can seriously affect the accuracy of flow measurement meters and regulating valves.

Entrapped air in any water system is an enemy to thermal efficiency. It is particularly damaging in a chilled water system which does not have the natural deaeration process of hot water. Spirax Sarco float operated air and gas eliminators, when installed at points where gases collect, will quickly, efficiently, and economically purge the system.
