We offer LIQUID COAGULANT BOILER SLUDGE CONDITIONER. PARAGON'S Liquid coagulant is a solution of a colourless, high molecular weight sludge conditioner used in both medium and low pressure boilers and tank to prevent sludge deposits. It is especially useful when feedwater becomes contaminated by oil. Dosing PARAFIX LIQUID COAGULANT to the boiler tank coagulates the oil droplets causing these suspended solid to settle to the low points of the boiler, where they are removed by blowdown.
