What is reason #5 to choose for a vacuum system ?
Active leak detection systems can either be a pressurised or a vacuum system (refer to FAQ 5). We recommend to use a vacuum leak detection system for several important reasons.
Reason #1 is: No risk of liner bulging (refer to FAQ 6)
Reason #2 is: Direct coverage of the complete carbon steel surface of a compartment (refer to FAQ 7)
Reason #3 is: A vacuum system is less prone to clogging (refer to FAQ 9)
Reason #4 is: A vacuum system does not restrict the leaking flow and does not built-up pressure or introduce risks for backflow (refer to FAQ 10)
Reason #5 is: A vacuum system also works when there is only one leak detection hole in a liner compartment.
But why is that ?
