There are 4 heat exchanger systems in the building, which have to be treated. For the business purpose, the hot water supply can not be interrupted. 4 sets of Vulcan S10 were installed to gently clean the heat exchangers and the whole piping system without stopping the machines.
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.
