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.
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.
