CORROSION - Inside and Out - causes heating equipment failures! BUT NOT WHEN YOU USE w GRID (miilOfl WHUwUlClUMl CORROSION internally, caused by elec trolytic actioo is eliminated because all metals in GRID Cast Iron Transfer Sur face in contact with steam are similar ... not 2 or 3 different metals that promote CORROSION that causes leaks and breakdowns ... do away with* high maintenance costs, repair work, and leaky heating equipment. CORROSION externally, caused by acid fumes cannot destroy GRID'S cast iron finned heating surface. Widely spaced fins cast integral with the steam chamber will not corrode externally.
