We use the screw trough as a large-surface heat exchanger – with outstanding properties and effects:
The steel screw trough becomes a heat exchanger by integrating water-conveying channels. In this secondary circuit, water is guided along the rear of the trough, absorbing part of the wastewater heat and transporting it to a commercially available heat pump. This heat pump increases the energy level and makes it available to consumers.
What is so special about this solution? The screw’s actual function is not affected in any way.
This adds up to huge potential savings for municipal and industrial customers!
