Waste heat recovery
Experts say that by the middle of the century the main source of power for heating buildings will mostly be energy from renewable sources.
Wastewater constitutes a great heat source.
Its recovery is difficult due to the nature of the medium, which is a suspension of solid particles. It demonstrates high corrosive potential and tends to deposit on waste exchanger walls, thus causing deterioration of heat exchange conditions, and thus a decline in heat exchanger efficiency. The best product for this type of applications are Hexonic tube-in-tube heat exchangers.
The have a fully dismountable design, allowing for mechanically removing the deposit layer from the surface. Exchanger stainless steel ensures corrosion resistance and its simple design ensures failure-free operation. A single exchanger section consists of a smaller diameter tube (wastewater side) installed inside a larger diameter tube (water side). The whole exchanger is made of an appropriate number of sections connected in series and installed on a frame. The number of sections depends on the type and working parameters of the media.
