Waste water recirculation system – no more crawling under the sink or flooding caused by loose hoses in the sink. With our ingenious tap adapter, the waste water hose is connected directly. Thus, the residual water gets into the drain or can be collected for later use.
The 500 flow limiter – the flow limiter slows down the water flow considerably and thus increases the pressure inside the system. A higher water pressure automatically leads to a higher daily output and improves the ultrapure water to waste water ratio.
Our system with extra rinse valve – the system is equipped with an additional flush valve. Regular rinsing rinses deposits on the membrane and rinsing stale water out of the system. This significantly increases the service life of the system and the membrane.
Multi-stage filtering: with an above-average daily output of up to 760 litres per day, the system reliably removes over 95 percent of all salts, hardness, pollutants and heavy metals as well as nitrate and phosphate or pesticides, viruses and bacteria.
Box contents: all accessories necessary to operate the system are included. Each step is explained in detail in the German assembly instructions and provided with pictures for better understanding.
