Main advantages of a CTU 

  • Designed to reduce limescale & improve the taste of incoming feed water.
  • The new system doesn't mix carbon with the resin, so regeneration becomes possible with positive results for the environment.
  • The carbon is located in the riser tube, which is the best place for polishing the water, giving maximum taste reduction.
  • The vessels use regenerated resin, which has a higher exchange capacity than new resin, so it will give maximum service time.
  • Fitted with " NRV male fitting on the inlet/outlet.
