Non-Clog Sludge Heat Exchanger Pump Package

Unlike traditional sludge heat exchangers and spiral sludge heat exchangers which can clog with rags and ropey fibres, a PSL Sludge System consisting of a Vaughan Chopper Pump and a Lackeby sludge heat exchanger ensures that clogging problems do not occur.

The heart of the PSL Sludge System is a Vaughan Chopper Pump which preconditions solids, rags and ropey fibres prior to the sludge heat exchanger and guarantees a non-clog sludge heat exchanger system. There is no need to use macerators or munchers as the Vaughan Chopper Pump performs both functions of pumping and preconditioning the sludge prior to entering the sludge heat exchanger.

To meet the requirements for the heating or cooling of sludge in Wastewater Treatment Plants, a Lackeby sludge heat exchanger is used with the PSL Sludge System.

This all stainless steel, insulated high performance sludge heat exchanger has large channels to provide a wide throughput area that keeps pressure loss low and minimises the risk of clogging. The unique patented open turning chambers contributes to a compact design that is simple to install. Inspection, disassembly and maintenance are made easy because the turning chambers are mounted on a common flange at each end of the heat exchanger. The turning chambers provide even higher heat transfer by equalising the sludge temperature profile.
