Nitrogen Blanketing Pressure Regulator

Tank Blanketing (Blanket Gas Regulator Valve)

Assentech Sales Limited offers Blanket Gas Regulators that deliver consistent gas pressure in your storage tank’s vapour space. Acting as a guardian for your storage vessel, these regulators discharge an inert gas, typically nitrogen, to inhibit the formation of a vacuum when liquid is evacuated and to maintain the desired blanket pressure during temperature fluctuations. This serves to shield the tank from external air contamination and to prevent the creation of potentially combustible or explosive atmospheres. With the capability of maintaining a blanket gas pressure as low as 0.5 InWC, these regulators limit the incursion of external air and moisture, significantly reducing the evaporation of the stored product. The result is a marked conservation of product and a significant decrease in tank emissions.
