Purge Air Systems protect high-voltage support insulators from moisture and dust that could accumulate on their surfaces and cause them to fail.

Support insulators provide many years of use when properly maintained, such as preheating prior to start-up. The constant flow of dry heated air prevents condensation and prevents flue gas from entering.

Volume, temperature and pressure of the purge air are critical design parameters that vary significantly.  Southern Environmental designs each purge air system to satisfy the specific requirements of each application.
