A non-pressurized external reservoir system acts as a protective buffer between the product and the atmosphere. Multiple seal arrangements are used to isolate toxic gases and fluids that can change state when exposed to the atmosphere. Buffer fluid is circulated between the inner and outer seal chamber using forced circulation with a circulating ring or pump.

Carotek also provides cooling coils to be placed in the seal reservoir to help reduce flashing of the product or the buffer fluid. A standard inner seal safely vents vapor to a recovery system so that zero emissions are achieved.

A pressurized external barrier fluid reservoir system supplies clean fluid to a pressurized dual mechanical seal with forced circulation. Pressurized barrier fluid is used to lubricate both the inner and outer seal faces. Maintaining the barrier fluid at pressure 25 to 30 psi above the seal chamber pressure insures barrier lubrication of the inboard seal faces.
