extends maintenance intervals

GRANDER water can remain longer in the heating & cooling circuit, in machines and plants due to its better durability and thus extends the maintenance intervals.

minimizes plant load

GRANDER water revitalization reduces the susceptibility to germs, limescale deposits, rust formation, silting and sedimentation and thus also reduces the load on your plants.

increases your productivity

The use of revitalized water according to Johann Grander reduces the susceptibility of your plants to repairs and thus ensures shorter downtimes and extended production intervals.

protects your plants

GRANDER water protects your plants and technical equipment, thus extending their service life and reducing your investment requirements.

reduces your efforts

The use of GRANDER water revitalization sustainably reduces your workload, the use of auxiliary materials and additives, and your energy expenditure.
