Lackeby Sludge Heat Exchangers, available at Pump Systems, are used for sludge/water or sludge/sludge heating applications based on a modular principle with circular sludge channels. This means the design is adaptable to different wastewater treatment plants.
Each level of sludge channels is surrounded by a rectangular water circuit, in which water for heating/cooling flows in the opposite direction to sludge. All turning chambers are mounted on a common flange which allows for easy inspection, disassembly and maintenance.
There is no size limitation as units are made to order and all sludge heat exchangers are constructed from stainless steel.
