Sub-flow filter GENO®-VARIO 3000 - consistently good circulation water

Sub-flow filter GENO®-VARIO 3000 continuously improves the circulation water of closed hot and cold networks. To compensate for lost water volumes (minor leaks, repair measures), GENO®-VARIO 3000 adds treated raw water to the circuit. For water treatment, the sand filter stage first removes all non-soluble elements such as scale, rust or dirt particles. The connected ion exchange system then performs complete softening. As a result, a water quality in line with the applicable guidelines VDI 2035 and AGFW 510 (VdTÜV 1466) can be achieved without a change to the system content. It is actuated manually via the fully automated control electronics.

  • Removal of rust and dirt
  • Softening
  • Automatic backwash and regeneration
  • No filter material exchange necessary
  • Simultaneous treatment of make-up water
  • Manual make-up water feed

Installation requirements

Please note local installation directives, general guidelines and technical specifications. The installation site must be frost-proof and the sub-flow filter protected against chemicals, dyes, solvents and vapours. If there are large amounts of course dirt, a course dirt filter must be installed upstream to protect the pump. The ambient temperature as well as the radiation temperature next to the system must not exceed 40 °C. A socket (230 V / 50 Hz) is required within a range of approx. 3 m of the system.
