Industrial Demineralizers help produce flawless finish for Whirlpool-Seeger A good sales talk is backed by practical chemical engineering. The gleaming synthetic enamel and porcelain finishes on RCA WHIRLPOOL Washers and Dryers are sprayed and baked on metal parts that are prepared for finishing in chemical and steam baths and then rinsed in water. Rinse water is a critical factor . . . even the finest drinking water can leave salt spots that cause finishes to crack and chip. Whirlpool-Seeger engineers have a minimum of rinsing troubles. They use the Industrial Demineralizers pictured above to obtain rinse water as pure as commercially distilled wafer. Result: A beautiful, lasting finish coat with virtually no rejects due to salt spots. The picture below shows another Industrial installation at Whirlpool-Seeger, a dualsoftener for supplying soft water to the plant boilers. It cuts maintenance costs by preventing scale and thus gives a better heat transfer. The company has four Industrial installations, each designed to do a specific task . . . each has been a profitable investment. industrial matches equipment exactly to the job, treating every installation as a unique problem, with complete chemical analysis and survey of methods and materials. This objective engineering produces equipment that becomes a real asset to your c o m p a n y — a tool f o r q u a l i t y control and greater output. If you will outline how you use water in processing, we will be g l a d to make recommendations and estimates.
