The system has been developed for applications requiring large volumes of RO water on demand. The efficient RO membranes reduce water wastage and provide excellent product water quality whilst ensuring high retention rates of water impurities. The built-in permeate distribution pump delivers the product water with up to 2 m³/h at 3.7 bar to the consumer end point. Therefore, no additional distribution pump is required to supply an entire building with type 3 water.
