September 30, 1916] ELECTRIC RAILWAY JOURNAL 103 SPRACO cos?kVNEcMs Did your turbo-generatorsloaf this Summer when thethermometer stood at 90 in theshade and the air was chokedwith dust? We know of scores of rail-way, light and power compa-nies whose turbines did notloaf. They were the turbineswhich were equipped withSpraco Air Washers andCoolers. These Spraco - aidedplants, showed higher gener-ator efficiencies, reduced fuelcosts, reduced maintenancecharges and ability to standthe gaff when the peakcame on.. TRADE MARK REGISTERED U. S. PAT. OFF. Lets hit the high spots of afew installations for you. The Spraco Washer of 60, 000cu. ft. capacity per minute en-abled the Pennsylvania Railroadto run its biggest turbine 23 hrs.a day for 18 months withoutcleaning. A drop of 5 to 15 deg.Fahr. was obtained. The Toledo Railways & LightCo. used a 70, 000 cu. ft. capacitySpraco to cool a 20, 000 kw.turbine. Though the plant waslocated on a very dusty street theSpraco absolutely preventeddust from getting into the ma-chine. Another customer droppedquantities of soot in front of theair intake but never a grain of itgot to the turbine. A 15 per cent reduction in fuelcost is easy with Spraco equip-ment. We can prove it.
