Heat Exchanger

Heat exchanger is used to heat the sludge inside the digester, as for a perfect fermenting conditions, a constant sludge temperature is required in the digester tank. In order to achieve this, the digested sludge is circulated in a pipe heat exchanger and is heated to the requested temperature through hot water in a countercurrent procedure. With respect to sludge quality, performance and energy efficiency, the heat exchangers are optimized for the respective case of application. It can be isolated with 60 mm mineral wool and aluminum lining.
