Heating Water Revitalisation:

The GRANDER® effect is clearly visible here:  dirty and often foul-smelling heating water becomes crystal clear in a short time.

Cooling Water Revitalisation (Industry):

Through the implementation of GRANDER® water revitalisation, reduction in maintenance and optimization of chemical use can be achieved.

Threaded connector with red brass nipples:

for prevention of contact corrosion.

Choosing the right device:

When selecting the right device, one has to consider not only the pipe dimension and peak usage times, but also the stress factor and the installation situation on site. Our trained GRANDER® consultants will provide customers with support and advice on making the right decision.

Installation in Heating Area:

The installation should be done, particularly in high temperature systems, in return flow after a possible dirt separator and to guarantee a problem-free system ventilation in a vertical pipe.

GRANDER® water revitalisation devices work with natural energy, without electricity or chemicals, and are completely service/maintenance-free.



Area of use: Heating systems, cooling systems and process water

Material: GRANDER® water revitalisation devices are manufactured in durable high quality V2A stainless steel, which ensures a long life span. For special applications, devices (from 3/4″ and above) are available in acid resistant stainless steel V4A.

Guarantee / Warranty: 3 years for material and manufactured defects
