Enhanced-sealing options and application-specific seal materials can help reduce vent leakage, breathing losses and avoidable fugitive VOC emissions while maintaining the required tank pressure and vacuum protection. They can be particularly useful when existing vents are leaking, chattering, sticking or poorly coordinated with tank blanketing or vapour-recovery setpoints. For VOC compliance projects, enhanced-seal vents are best evaluated as part of the complete tank pressure-control system, including vent sizing, setpoint spacing, seal-material compatibility, blanketing and vapour handling. Final equipment selection should be based on the tank service, operating conditions and applicable regulatory requirements.

Spartan also has a low-pressure mobile testing unit that can test atmospheric-tank pressure and vacuum relief devices in the field, including leakage testing.
