Every month the heat exchanger efficiencies dropped dramatically because of an increase in pressure between inlet and outlet of the heat exchanger. Vulcan S250 models were installed and after 5 months there have not been any mineral scale pressure issues in the cooling towers or heat exchangers.
After 4 months, no white scale was seen, only yellow rust was left. Although there were still substances in the plate heat exchanger, they had been softened This cleint stopped using all additional chemicals and water softening equipment to treat their water as part of this 4 month test. Although there were still substances in the plate heat exchanger, it was soft and could be easily removed by manually. There are no more white mineral scales on teh heat exchanger plates, only yellow-brown impurities left.
