The AAT heat exchanger is used to heat the digester sludge in the digester.
For perfect fermenting conditions, a constant sludge temperature is required in the digester.
In order to achieve this, the digester sludge is circulated in a pipe heat exchanger and is heated to the requested temperature through hot water in a counterflow procedure.
With respect to sludge quality, performance and energy efficiency, the heat exchangers are optimisted for the respective case of application.
