You may be doing Just that if your plans don't include CHLORINATION EQUIPMENT for slime control by WALLACE & TIERNAN. Chlorination equipment because it controls slime that prows on the walls of condenser tubes not protected against It Enough of the growth even tually seriously reduces heat transfer efficiency -- actually insulates your steam from the cooling water. Back pressures go up, production drops, oper ating and maintenance costs rise, and eventual shutdown becomes necessary for regular clean-out periods. Wallace & Tleruan equip ment because it is versatile, sturdy and dependable -- proven by thousands of success ful .installations, vouched for by satisfied users everywhere* and because there'B a Wallace & Tiernan chiorfnator for every job. Write today for informa tion on how Wallace & Tlernan chlorination may help you solve your slime problem. No water ,, is I SUME-FREf CM**,0* the h#,W reducerJliatlon mat<e-up or V, water.
