Emerson Automation Solutions introduces the Enardo ES-665 spring-loaded thief hatch for use on low-pressure storage tanks in oil and gas and other industries. The ES-665 is reportedly engineered with increased sealing forces and a tight and consistent fit of the sealing surfaces. The resulting emissions performance of the Enardo ES-665 thief hatch is 0.10 SCFH (standard cubic feet/hour) at 90% of setpoint*. The Enardo ES-665 also helps conserve tank contents.
The ES-665 provides tank access as well as pressure and vacuum relief to accommodate tank pressure changes that occur under normal conditions. The ES-665 also limits hatch emissions when pressure or vacuum relief is not required.
In addition to its emissions performance, the ES-665 includes:
- An available center assembly for improved performance of previously installed models.
- Multiple relief settings and material options for application flexibility.
- A latching and lockable lid for added security and safety.
