Groth 3011 Blanket Gas Regulator
The Groth 3011 Blanket Gas Regulator ensures that constant gas pressure is maintained in the vapour space of a storage tank. When liquid is removed from a tank or the temperature is reduced, a vacuum would be developed. With the Groth Blanket Gas Regulator, a blanket gas is supplied to prevent any vacuum from developing and to maintain the desired blanket pressure.
In addition to preventing outside air and moisture from entering the storage vessel, a blanket gas pressure, as low as 1–2″W.C., reduces the evaporation of the stored product to a negligible amount. The result would not only conserve product but would also greatly reduce emissions. The advantages are in addition to the fire protection that is provided.
