The very hard to obtain US-patent protection for the ESU System has now been officially approved by the authorities of the United States Patent and Trademark Office. There was no doubt about the unique characteristic of the energy saving system developed by extrutec.

The ESU System converts the residual energy contained in the exhaust gas of the heating system into hot water and then applies it to the bars located in the feed conveyor table. The latest version of the ESU features a heat exchanger developed and manufactured by extrutec.  Within the latest real time monitoring, the Eco Shower Unit saved over 18% of gas consumption.
