Blanket Gas Regulators
Blanket Gas Regulators from Groth Corporation ensure that a constant gas pressure is maintained in the vapor space of a storage tank. A blanket gas regulator supplies an inert gas to prevent a vacuum from developing when liquid is removed from a tank, to maintain the desired blanket pressure when the temperature drops, and to prevent outside air from contaminating the tank or creating a flammable or explosive environment. A blanket gas pressure as low as 0.5 InWC prevents outside air and moisture from entering the storage vessel and reduces evaporation of the stored product to a negligible amount. The end result: product conservation and significant reduction in tank emissions.

Combined Pressure/Vacuum Valve and Flame Arrester
The Model 8800A Pressure/Vacuum Valve & Flame Arrester combination units are designed to protect your tank from damage created by over- pressure or excessive vacuum, at the same time that they provide protection from externally caused sources of heat and ignition. The result is increased fire protection and safety.
