Exchanger SUP-2, suitable for a water heavily contaminated with a fatty deposits, was devised with twin absorbers connected in series on six levels. Approximately 21°C of heat is transferred in to the clean water during 24hr production from 260 m3 of around 45°Cwarm waste water.

Daily energy saving during non stop process in 6500 kWh. Projected investment return: 9-10 month.

Further benefit is the removal of the water cooling costs during the final filtration stage prior to discharge in to the river.

In operation since: 1.10.2008
Input average temperature of the river water: 12 oC 260m3/day
Waste water: 45 °C 260m3/day.
