Yet here-and-now (acts on the condition o! internal boiler suriaoos' are always yours when * APEXIOR NUMBER 1 guards tube anddmm steel. I; y : For APEXIOR permanently stablUses metal beneath a surface which moisture cannot penetrate. Thus isolated from any environment with which U can react to its own detri ment, APEXIORlxed steel loses . none of the characteristics of new cit newly cleaned metal--can be depended upon for changeless year-in, year-out service. A further benefit is that APEXfOR's smooth surface at tracts lower and less tenacious deposits so that tubes and drums stay cleaner longer for uniform heat distribution, bettor circula tion and constant high heat transfer efficiency. These are some of the reasons why for 31 years APEXIOR has played so important a role In the power plants of American industry -- why today engineers in everIncreasing numbers specify it for boilers of aU pressures and ratings, ' operating under, all conditions of foodwater control.

I keep lube oil--either turbine lube or Diesel lube--both clean and dry.. - "Being able to remove both contaminants of lube oil at one time gives me an advantage. It means that when I am on the job of protecting a power unit, the engineer never has any worries about dirt or condensate.' Whether' I am called on to remove a few drops of moisture or quickly to remove a dangerous "slug" of water, I can do it. De Laval machines, properly selected for capacity in the. first place, have ample reserve capacity to take care of an emergency. "When I purify Diesel fuel oil, I enable the operator to get maximum effective usefulness from his fuel oil. "I'm written up in Bulletin 400 (Turbine Oil) and Bulletin DL-1 (Diesel Oil).
