Low pressure Dryer is a pressure vessel charged with solid anhydrous carbide that sucks up the moisture in the gas. We ensure that it is solid and long-lasting and is of highest quality. It improves the overall performance of the acetylene plant. Being charged with calcium chloride, the dryer absorbs the moisture in the gas. If some of moisture is necessary to enable the chemical purifier to function effectively, it is ensured that a provision is made for a by-pass for allowing a allow part or whole of the gas to be directly admitted into the chemical purifier.
