How is Spencer saving over $200 per month by switching to the GW24?

With Spencer's previous glasswasher, a CMA model GL-C, he used 2 gallons of Iodine based sanitizer per week (8 gallons per month for a total of $256). With the GW24, he now uses just over 1 gallon of Chlorine based sanitizer per month (1.3 gallons per month for a total of $10.40). The GW24 uses 84% less rinse water and associated sanitizing chemical at rated capacity. This alone accounts for a per hour sanitizer cost reduction from $4.20 to $0.66. In addition, changing from Iodine based to Chlorine based sanitizer reduced the per hour cost of sanitizer further to $0.16. See chart below for technical data comparing various rotary glasswashers.
