Heat Exchangers

Lackeby Products offers an entire range of heat exchangers developed for the special requirements set for the treatment of sludge and similar media. The heat exchangers combine new thinking and 40 years of experience in compact designs with minimal maintenance needs. Since the 1990s, our heat exchangers have been installed at municipal and industrial plants worldwide.

Heat exchanger sludge/sludge

Lackeby Products produces heat exchangers sludge/water based on a modular principle with circular sludge channels, which means the design can be adapted to each plant’s unique conditions. The channels provide a large throughput area that keeps pressure loss low and minimises the risk of clogging. Each level of sludge channels is surrounded by a rectangular water circuit, in which water for heating/cooling flows in the opposite direction to the sludge.
