The Enardo ES-665 spring-loaded thief hatch for use on low-pressure storage tanks (photo) is engineered with increased sealing forces, as well as with a tight and consistent fit of the sealing surfaces, resulting in emissions-reduction performance of 0.10 std. ft3 /h at 90% of setpoint. 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. The device also features an available center assembly for improved performance of previously installed models, multiple relief settings and material options and a latching and lockable lid for added security. — Emerson Automation Solutions, St. Louis, Mo.
