Efficient energy optimisation

The Lackeby Heat exchanger sludge/water is a uniquely designed unit for medias with a high viscosity. The patented turning chambers enable us to design the heat
exchangers for the highest possible heat transfer as well as meeting demands for a small footprint. The design also ensures that the heating or cooling system
runs with as low a load as possible in order to keep the operating cost low.

Advantages

Modular design sludge/water heat exchangers from Lackeby are robust, compact, easy to install and maintain and are highly reliable. Circular sludge channels ensure that large particles can be managed but also keeping the risk for clogging to a minimum. The innovative design with patented turning chamber assures high energy
transfer and low pressure losses. Further on, this robust and modularized product have all features for high reliability and low maintenance requirements.
