GRANDER® Submersion Units are mainly used in pre/post-revitalisation in combination with in-line GRANDER® Revitalisation Devices. They have been proven to be outstanding when used in standing water. This holds true particularly for water tanks piled up (i.e. on ships) or for water in storage.

In drinking wells and containers, the use of a large Double Cylinder (for a maximum of two households) is recommended in order to maintain the revitalisation effect in treated water.


GRANDER® Submersion Units operate with natural energy, without electricity, additives or any service/maintenance.
