Chalk, while indispensable to man, is a ruthless enemy to our sanitary installations. HOLPRO® brings a practical, economic solution that is environmentally friendly.

HOLPRO® protects your sanitary installations and household appliances from the damage caused by limescale in two ways :
  • - prevention against the formation of limescale
  • - curative effect, to gradually dissolve existing limescale
As HOLPRO® uses a natural physical process it does not require chemicals. It does not pollute the environment and considerably reduces over-consumption of fuel due to scaled piping.

HOLPRO® delivers drinking water, retaining all its mineral properties. It uses little electricity, is hard-wearing and requires no maintenance.

HOLPRO® is generally installed after the meter, on all types of piping with no need for plumbing work.
