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.
Groth blanket gas regulators provide a controlled gas environment in storage tanks for the following applications:
• Simple operation, spring-loaded “push-push” balanced piston design • Bubble-tight shut-off • Variable orifice, field-adjustable flow capacity • Single stage regulator • Setting ranges from 0.5 InWC to 15 psig • Modulating opening • Minimal lockup and droop
