When You Think of CORROSION PROTECTION for your STEAM SYSTEM 7^ Because QSQES^&firrulatos to Control Corrosion CORAVOL IS PART OF A COMPLETE TECHNICAL SERVfCf which provides pedal chomlcal formulas for . . . boiler feed wafer . . . foam prevention . . . hot water supply ... re* frigerating brine .. . cool* Ing and condenser water . . . rapid scale removal ... coagulation ... algae control . .. fuel oil supply . . . toot removal. CORAVOl circulating throughout your steam system protects it from corrosive attack. CORAVOL saves costly pipe repairs and r&plocantanH--maintenance laborhours and days of shutdown loss. CORA* VOL cleans out clogging rust deposits. Im proving heat transfer, restoring original capacity af lines and efficiency of voWes and traps. CORAVOL, the origlnol* amine process, has the flexibility that lets It conform to eoch Individual need. The CORAVOL you' will use Is formulated to do the best protective job under your own plant conditions. * *f 'Ml p*rt***, grant!
