The 3000 Series 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" W.C. prevents outside air and moisture from entering the storage vessel and reduces the evaporation of the stored product to a negligible amount. The result conserves product, greatly reduces emissions, and protects the tank from external fires. Click here for more information.
