GRANDER water revitalization devices consist of a revitalized water core in a weakly magnetized metal housing. The water for the core originally comes from the spring of the copper mine in Jochberg and is produced by means of a generator developed by Johann Grander.
Through the interaction of the effects of the magnetic field applied by the GRANDER water revitalizer in conjunction with the water core prepared according to GRANDER, the water revitalizer is able to transfer natural impulses to the water without coming into contact with it itself.
This effect has been proven, tested and confirmed in two studies conducted by European universities using the experimental setup with GRANDER Energy Rods Double. Thus, the tap water is stabilized and regenerated in a natural way.

Yes, in 2016 and 2021, two scientific studies on the topic of "magnetic water treatment" and the effect on microorganisms - using GRANDER water revitalization devices - were conducted in cooperation with European universities and published peer reviewed in scientific journals.

The following statements are proven and confirmed in these tested studies:

Study 1 from 2016 proves that the use of GRANDER water revitalization units, reduces the formation of settling lime crystals. Instead, dollops (= precursor of lime crystals) are formed, which are dissolved in the water and rinsed out.

Study 2 from 2021 proves:
1. "It is scientifically proven that the GRANDER Energy Rod Double positively influences the naturally occurring bacteria in the water."
2. "A kind of pro-biotic effect is established in the water due to the GRANDER Energy Rod Double."
3. "It has been shown that the GRANDER Energy Rod Double increases the number of desirable naturally occurring bacteria in the water."
4. "The authors see great potential in the GRANDER Energy Rod Double water wore magnet as an alternative tool for microbial management of drinking water supply chains and for biological stabilization of drinking water."

Yes, the theoretical principles of GRANDER Water Revitalization have been scientifically proven.
The interdisciplinary scientific collaboration of European universities and research institutes(1) in Europe's Center of Excellence for Sustainable Water Technology - WETSUS - brought a breakthrough in the understanding of magnetic water treatment (MWT) from the perspective of water physics.(2)
The scientific results of Dr. Elmar Fuchs(3) and his team/WETSUS(4) "Strong Gradients in Weak Magnetic Fields In-duce DOLLOP Formation in Tap Water" could be confirmed in a scientific peer review process.(5) In 2012 Coey published a theory about the mechanism of magnetic water treatment based on the gradient of the applied field and not on its absolute strength. The new scientific work of the WETSUS Applied Water Physics research group is based on the finding that calcium carbonate nanoparticles ("DOLLOPS") - contained in tap water - restructure under certain conditions (including those caused by the magnetic gradient), thus changing the environmental conditions for solutes (e.g. lime). (6) The results of the study show an increased formation of nanometer-sized prenucleation clusters (like oxyanion polymers or "DOLLOPS"). They are thus consistent with Coey's theory, which is therefore applicable to very weak magnetic fields as long as they contain strong gradients. >> Scientific Results, as of 2019 1) Listing Universities: www.wetsus.nl/research/research-institutes

The company IPF GmbH was founded in 1992 and is located in Jochberg. It is the research company of GRANDER.

In order to be able to guarantee unhindered scientific work on further studies on the topic of "applied water physics" and GRANDER, it was agreed with the authors and institutes of the first study to maintain confidentiality until 2019. Furthermore, it was agreed to name the water core magnet used in the study - for the reasons mentioned above - as a product of the GRANDER company IPF.

The internal structure, also in relation to the lime structure, is the decisive factor for the properties of water. Structural changes simultaneously lead to changes in the properties. The special feature of GRANDER Water Revitalization is that it specifically and sustainably stabilizes water structurally and positively changes its physical as well as microbiological properties.

Due to the regained order and stability of the water structure, as well as the associated change in physical and microbiological properties, the water quality is significantly improved. On the physical level, this results, among other things, in a high solubility of the water, which in turn enables a more economical consumption of detergents and cleaning agents. In addition, transportability of undissolved substances in the water is promoted. This reduces the formation of limescale and, subsequently, of deposits and rust. In terms of microbiological properties, the high self-cleaning power and resistance of revitalized water are particularly noteworthy: The water revitalized by GRANDER is more resistant to new loads, and therefore has a longer shelf life and a lower germination potential.

The use of a GRANDER water revitalization does not cause any changes regarding the following properties of the water:
Hardness level, chemical ingredients, as well as disinfection properties.
(Note: Even though the post-contamination potential has been shown to be reduced in water revitalized with GRANDER, water is generally not considered a disinfectant!)

According to documented experience, there are no time limits to the effect. Many devices have already been in use for more than 40 years, and yet their effect is still given to the full extent.

With GRANDER water revitalization, the lime behavior in the water changes.

• Lime remains in the water
• Lime becomes finer
• the high carrying capacity and transportability of GRANDER revitalized water reduce the tendency to form lime deposits
• Lime is easier to remove
• Limescale deposits are reduced - this increases the inventory protection of pipes, boilers, etc. and reduces the energy consumption
• the entire cleaning process is simplified, as the lime is easier to dissolve
• the intervals for descaling coffee machines, fittings etc. are extended according to DIN 1988-200
• up to a total hardness of 14 German hardness no ion exchanger is required (DIN1988-200)
• This scientific work by the Wetsus research group "Applied Water Physics" (Martina Sammer, Cees Kamp, Astrid H. Paulitsch-Fuchs, Adam D. Wexler, Cees J.N. Buisman and Elmar C. Fuchs) is based on the finding that - in tap water contained - calcium carbonate nanoparticles ("DOLLOPS") restructure under certain conditions and thus change the environmental conditions for dissolved substances (e.g. lime).
• The results of the study show an increased formation of nm-sized prenucleation clusters (like oxyanion polymers or "DOLLOPs"). They are thus consistent with Coey's theory, which is therefore also applicable to very weak magnetic fields as long as they contain strong gradients.
• Minerals calcium and magnesium, which are important for the body, are preserved
• Lime has a positive effect on the taste of water
  

The corrosiveness in revitalized tap water is lowered or stabilized - this also reduces the formation of rust in the piping systems, including all sanitary installations.

Substances such as heavy metals and drug residues can only be removed by pollutant filters (e.g. reverse osmosis or activated carbon block filters). However, water revitalization is very useful after such effective pollutant removal in order to restore optimal conditions at the structural level of the water as well.

There are some different methods to change water, such as water treatments by magnets, electromagnetism and the like more. All of these methods can have an effect on the taste, appearance or behavior of the water in terms of lime and corrosion properties. However, the special feature of GRANDER Water Revitalization is its much broader spectrum of effects.
In addition to the above-mentioned physical properties, it is mainly the microbiological properties (self-cleaning power, high resistance, long shelf life, reduced post- germination...) that make the water revitalized by GRANDER special. The influence on microorganisms, was also the reason why Johann Grander gave his process the name "water revitalization". "Life literally returned to the water", the visionary held in reference to it.

No. The property word "dextrorotatory" is correctly used mainly only in connection with lactic acid and screws.

The answer - considering the current state of science - is no.
In hydrology, the term "hexagonal water" refers to a hypothetical form of water that might occur under certain conditions.
The theory is that it is an ordered structure of water molecules forming a hexagonal arrangement. This hexagonal structure is believed to be maintained by hydrogen bonds between the water molecules. Some researchers have theorized that hexagonal water may have certain unique properties, such as increased viscosity, a negative charge, and an enhanced ability to store energy.
It is also thought that it may play a role in living organisms, particularly in relation to the transport of substances and cellular function.
It is important to emphasize that the existence and properties of hexagonal water are still controversial in the scientific community and further research is ongoing to confirm its presence.

A GRANDER water revitalization unit is ideally installed directly in the central water supply line. For this purpose, we offer suitable versions and unit sizes for all common installation situations (house supply line, apartment supply line, ...). In the rare cases where installation in the central water supply line is not possible, small GRANDER devices can also be installed at individual tapping points (e.g. under the kitchen sink or shower faucet). Important for apartment tenants: You can have your device(s) removed when you move, take them with you and continue to use them in your new apartment. Installation is usually very simple and is carried out by a specialist.

» The Use of GRANDER Water Revitalization

GRANDER water revitalization units are installed by your specialist installer. The mostly extremely uncomplicated installation is carried out according to the enclosed installation instructions and is performed with commercially available parts.

In addition to the pipe dimension, the peak consumption, the load factor of the water and the local installation situation must also be taken into account for the selection of the correct device. Under no circumstances should the pipe dimension be undercut.
Our GRANDER contact persons will support you in selecting the right unit size.

GRANDER water revitalization units are a quality product manufactured in Austria. They are made of high-quality stainless steel in a robust design and thus guarantee lasting durability as well as many years of customer benefit.

GRANDER water revitalization units operate without electricity and without additives - they are service and maintenance-free.

Yes. If devices for conventional water treatment (e.g. ion exchangers, UV disinfection systems, magnetic devices...) are required or prescribed, GRANDER can additionally support these systems, but cannot replace them. In principle, the GRANDER device should be installed within the water supply line after such treatment units.

Optimal customer service is close to our hearts. For this reason, we have chosen the distribution channel of personal consultation with on-site visits in the past. Expert GRANDER contact persons and selected installers provide information about the possible applications as well as the many benefits of GRANDER water revitalization. Let us advise you without obligation and free of charge - Fill out our Contact form and we'll reach out to you.

The requirements or tasks are often very different, which is one reason why on-site consultation is so important to us. Small systems for apartments are correspondingly less expensive.
The investment in a GRANDER water revitalization system is a one-time purchase, as there are no time limits to its effect. Further use takes place without follow-up costs such as maintenance, service or electricity costs.

Until 2016, these reports were based primarily on empirical research and in-house studies by IPF from the GRANDER group.
The positive effects of water revitalization could be observed for more than 40 years in various fields of application (private, swimming pools, trade, industry, agriculture, etc.).
Since 2016, tested scientific studies have impressively proven the positive effects of GRANDER water revitalization.

The main application of GRANDER water revitalization is in the drinking water sector. People who place particular value on drinking water quality appreciate above all the fine taste of revitalized water and the pleasant feeling on the skin when bathing and showering. Garden lovers quickly find pleasure in GRANDER, since plants react just as positively to revitalized water: GRANDER revitalized water promotes lush and vigorous plant growth. In addition, contaminated heating water can become clear and odorless again within a few months by installing a GRANDER unit in the heating system, while at the same time the tendency to rust and sludge formation is significantly reduced. In swimming pools, bathers usually feel the change through the revitalized pool water, which is perceived as significantly softer. In addition, detergents and cleaning agents can be used more sparingly due to the high dissolving power of revitalized water.

Nowhere is the area of application of GRANDER water revitalization as diverse as in the hotel and gastronomy industry. In addition to drinking, shower, bath, heating and swimming pool water, the kitchen is also one of the most important areas of application. In addition, revitalized drinking water directly from the house water pipe is increasingly appreciated by guests. Numerous food manufacturers also regularly recognize the leap in quality that GRANDER water revitalization additionally gives them. The wide range of suppliers extends from cheese dairies and butchers to fruit and vegetable producers to mills and bakeries, who report the improved taste and long-lasting freshness of their revitalized products.

Breweries and beverage producers report positive changes in carbonation behavior and savings in cleaning processes of their beverages. In agriculture, the goals of GRANDER water revitalization are improved nutrient uptake by plants through optimized manure and improved animal health. Gardeners appreciate the positive effects of revitalized water on plants. Wherever water has an important function, commercial users also benefit from GRANDER water revitalization.

All International Commercial Businesses Using Grander

In industry, only facts and measurement results are important. GRANDER water revitalization is used today primarily in the plastics and metal processing industries, where water plays an essential role in production processes. First and foremost, it is the cooling circuits that pose challenges for many companies: The cooling of machines is a crucial production factor for them. However, silting of the cooling water due to an excessive amount of bacteria not infrequently leads to production downtimes or failures. GRANDER water revitalization has always been able to achieve similar results, confirmed by measurement protocols, in numerous companies: a significant improvement in the cooling water quality, a noticeable reduction in odor nuisance due to the improvement of the bacteriological situation, a decrease in rust formation, a reduction in production downtimes and, in the majority of cases, a significant reduction in costs due to savings in chemicals. In addition to the technical and economic benefits that can be achieved through GRANDER, most companies are also concerned about sustainability as a result of the reduced impact on water as a resource. The many positive results are prompting internationally renowned companies to publicly acknowledge their operational successes with GRANDER.

The successes of GRANDER water revitalization in industrial applications were also confirmed in 2007 within the framework of the empirical diploma thesis at the University of Graz. For this purpose, industrial companies from Austria, Germany and Switzerland that use GRANDER were examined.

Since 1979, GRANDER has been the original in water treatment based on natural water revitalization. The international success of GRANDER water revitalization proved the company right and made it possible to establish a worldwide distribution network. After more than 40 years of market presence, GRANDER is now represented on all five continents.

"Every good thing also has its opponents," Johann Grander once said. Accordingly, GRANDER also accepted the right to question the water revitalization process for many years.

In the past, the skeptics considered everything to be parascientific that could not be explained by the available methods of science at the time. In addition to GRANDER water revitalization, this included areas of complementary and alternative medicine and even acupuncture.
Empirical studies, peer reviews, and scholarly papers on GRANDER have been all too readily denigrated as anecdotal user bias.
Thanks to audited, published scientific studies from European universities in 2016 and 2022, this has now come to an end.

No.
In the years 1999- 2003, a PR dispute between the external GRANDER distribution company U.V.O in Seefeld/Tyrol (PR consultant Hans Kronberger /EU member of parliament FPÖ Vienna) and the water biologist Dr. Erich Eder (district councilor /Green Party Vienna) took on a life of its own.
A lawsuit filed by the distribution company U.V.O against Dr. Erich Eder because of his baseless accusation of commercial fraud could no longer be prevented on the part of the GRANDER Jochberg company.

The consequences of the verdict are well known, one party may no longer speak of fraud, the others may continue to say esoteric nonsense. So far, so good.
In the course of internal restructuring measures of the U.V.O - Seefeld (however - erroneously communicated in retrospect - under GRANDER Jochberg), a dispute escalated between the private individuals Kronberger and Eder.

These process trajectories are documented between 2006-2016 with exact naming of participants on Psiram, Gwup, Eder HP, etc.

The trial between Dr. Kronberger and Dr. Eder took place because of a (far-fetched) formal error and had nothing to do with the company GRANDER Jochberg or its products.
It is documented that the public communication of the above-mentioned platforms and authors from November 2012 in the wording to exchange the true involved process partners (UVO & Kronberger) against the company GRANDER Jochberg (deletion of own content about it included).

This is the assertion of a Viennese biologist and founding member of the "Viennese Skeptics", where the court came to the conclusion that this assertion is a personal evaluation, which falls within the scope of personal freedom of opinion and therefore
cannot be prevented by the courts. This does not mean, however, that the court itself would have made the judgment that GRANDER is an "esoteric nonsense", as it is often erroneously presented.

No, this accusation from a skeptic in 2008 is based on the fact that internal knowledge about the production of GRANDER water revitalization devices was not published or communicated by the company at that time.
Since the devices work on the basis of magnetism without the supply of electricity, this accusation is invalid.
