GRID costiiumcofukidiimBUT NOT WHEN YOU USE unit heaters blast heaters t RADIATORS CORROSION Internally, caused by electrolytic action as in copper tubes, can't happen in GRID'S cast iron steam chambers and headers. Nor can acid condensate corrode the bottom connections. Cast Iron, internally, resists cor rosion. CORROSION externally, caused by acid fumes cannot destroy GRID's east iron finned heating surface. Widely spaced fins cast integral with the steam chamber will not corrode externally. GRID HORIZONTAL BLOW UNIT HEATER DATA Unit Hater Model Crater iXT -opacities at I PSIG Steam 60* P Eat.
