Industrial / Brewery hot water pump control
« on: October 22, 2013, 03:25:39 PM »
Our hot water system is a pumped rather than a pressure system. The 130 gpm pump is currently manually controlled, and tends to run continuously during operating hours. I would like to switch it to on-demand, and the CSV sound like just what I'm looking for.
Our problems stem from the high temperature of the water, 195F, and the extremely high carbonate hardness of our water. Valves do not last long in our hot water system, especially check valves (we've tried all styles, and none last more than a few weeks). The culprits are heavy deposits of calcium carbonate and corrosive CO2 gas.
Will a CSV survive in these conditions?
