V-COR 221 corrosion inhibitor is a liquid blend of sodium bisulphite and a specially selected catalytic agent, which will not interfere with boiler operations. V-COR 221 used to prevent corrosion in steam generating systems by removing dissolved oxygen from feedwater and boiler water.

V-COR 221 reacts with oxygen in water almost instantaneously even at low temperatures. This rapid rate of reaction provides greater protection to the boiler and
pre-boiler section, especially where mechanical deaeration is not complete.
