Efter 2,5 år gik vores Drobson 2500 i stykker, idet tÊnd og sluk lampen kan lyser svagt og den ikke lÊngere fungerer korrekt tilsyneladende, da vi igen kan mÊrke meget kalk i vores vand. Har ellers vÊret glad for produktet mens det virkede, men 2,5 års levetid er simpelthen for kort tid.

From White to Red: Understanding Limescale Changes After Dropson EMI 4000 Installation

After installing the Dropson EMI 4000, I observed that the limescale in my electric kettle changed color from white to reddish, without a noticeable reduction in buildup. This article explains the reason for the color change, the difference between white and red limescale, and how the technology interacts with local water conditions.
White limescale mainly consists of calcium carbonate (CaCO₃) formed when hard water is heated. It appears chalky and dissolves easily in household vinegar. After using the Dropson EMI 4000, the limescale turned reddish, likely due to iron in the water supply, which oxidizes into rust (Fe³⁺ oxides) during heating.
Dropson’s technology is designed to modify the crystal structure of calcium carbonate from calcite to aragonite. This process does not remove the minerals from the water but changes their form. However, in areas with iron-rich water, the altered structure can more easily trap iron particles. The resulting deposits become darker, harder, and less soluble in mild acids, requiring stronger cleaners such as citric acid.
In practice, users in regions with iron-containing water may experience tougher, reddish deposits despite the system’s intended benefits. These findings suggest that performance can vary depending on local water composition, and consumers should be aware of this before purchase. I do not recommend this product as it has intensified lime problem at my house.
Thank you for your technical comments. As noted, the presence of iron in the water can strengthen limescale due to its binding effect, which may explain why the device did not perform as expected.
Unfortunately, the warranty certificate was not completed by the seller. Since the warranty clearly states it is invalid without the seller’s signature, I was unable to claim coverage. I have submitted a complaint to the relevant authorities, supported by photos showing reddish deposits on my bathroom floor and electric kettle.
Although the product carries an EU certificate, it appears that the certification tests were performed under laboratory conditions, which may not reflect real-life use. I was also asked to provide official test results, which I believe limited my protection under the EU Consumer Act.
In summary, I was left without warranty protection or effective consumer rights, despite acting in good faith when purchasing the product.
Thank you for promptly offering a solution to my issue — it shows your great sense of responsibility and commitment to customer satisfaction.
I have used the link and sent an email with the required documentation. I also plan to share your helpful response on Trustpilot as a gesture of goodwill and appreciation for your excellent customer care.
I communicated with Dropson officials in Spain, and their representative personally came to my house to discuss the situation. After our discussion, we mutually agreed to dismantle the unit, and I received a full refund. The issue was handled professionally and directly. Thanks for their understanding and probably my case was a local issue.

UPDATE RESPONSE

Dear Customer,

We regret your frustration regarding the unsigned warranty. While this is a matter for the seller, Dropson prioritizes your satisfaction.

Please contact our technical team via our form at:
https://dropson.com/en/anti-scale-system/contact-dropson/

We will gladly provide recommendations on complementary iron treatment solutions, designed to work in synergy with the anti-scale protection offered by your Dropson system, and explore how we can assist you with the warranty issue.

We hope to help resolve the matter and kindly ask you to consider updating your review.

Thank you.

________________________________
Dear Customer,

We sincerely appreciate your detailed review and the effort you put into describing your experience with the Dropson EMI 4000. Your observation regarding the reddish discoloration of the deposits in your kettle is highly valuable, as it allows us to address an important aspect of water quality. As a technical engineer at Dropson, I’d like to offer a clear technical perspective on the matter.

It is essential to remember that the core mission of our EMI technology is scale prevention. Dropson is designed to transform calcium carbonate (the scaling component) from its adherent form (calcite) into a non-adherent form (aragonite). This effectively protects your pipes, heating elements, and appliances from limescale damage and energy loss, ensuring optimal operation throughout your installation. In this regard, your Dropson EMI 4000 continues to work diligently to shield you from hard water scale.

Your analysis of the presence of iron in the water is spot on. The reddish coloration is a clear indication that your water supply contains dissolved iron, which oxidizes upon heating and precipitates as iron oxides. The Dropson technology specifically targets calcium carbonate and does not alter the composition of other minerals such as iron.

What you’re observing in your kettle is a co-precipitation phenomenon. Although Dropson converts limescale into aragonite (which is easier to clean), when iron is present, these aragonite microcrystals can closely bind with the iron oxides that also form upon heating the water. This combination results in deposits that, while containing transformed aragonite, take on the reddish hue of iron oxide and may appear “harder” or less soluble using standard cleaning methods, as iron oxides require specific treatments (such as the citric acid you mentioned) for removal.

The presence of iron in water varies significantly depending on the region. While Dropson is not designed to remove iron, its effectiveness against limescale remains constant. The perception of a “worsened limescale issue” due to iron is a specific interaction related to the unique chemistry of your water—not a general problem. The vast majority of our customers benefit from superior limescale protection, as limescale is the primary fouling agent in most installations.

We understand that the visual and cleaning experience in your kettle may not have met expectations, and we would like to assess your case more thoroughly. Therefore, we invite you to book a technical consultation so we can analyze the specific profile of your water. This will allow us to confirm the presence and concentration of iron and propose complementary solutions for its treatment. It is important to note that these solutions will work in perfect synergy with the anti-scale protection already provided by your Dropson unit, ensuring a comprehensive approach to all water-related challenges.

Please reach out to our technical team through https://dropson.com/en/anti-scale-system/contact-dropson/
. We are here to ensure that your overall experience with Dropson is fully satisfactory and to address any challenge posed by water chemistry, guaranteeing the protection and efficiency of your entire installation.

Sincerely,
The Dropson Team

Vi kÞbte en EMI 4000 tilbage i 2022

Vi kÞbte en EMI 4000 tilbage i 2022, den er lige gået i stykker.. ingen lys i enheden mere samt ingen lyde fra den.
Det er godt nok lidt for tidligt sådan en går i stykker.
Hjemmesiden vi kÞbte fra er så lukket siden vi kÞbte, så det er nÊrmest umuligt at få fat i selve dronson, jeg aner ikke hvor jeg skal kontakte dem...

Vivo en una zona de agua muy dura y siempre hemos tenido problemas con la acumulación de cal.
Me recomendaron instalar un antical, pero no quería que fuera de sal por lo que contaminan y descubrí este antical físico.
La persona que me lo instaló me dio mucha confianza, viene con garantia y con un estudio personalizado adaptado a mi vivienda. Y lo que más me ha sorprendido es que no necesita mantenimiento ni consumibles.
De momento estoy muy contenta con el.

Hejsa,
Har også prÞvet Dropson EMI2500 - har absolut ingen effekt. Vandskål til husdyr kalker til fuldstÊndig som fÞr. BadevÊrelse, toilet, vandhaner er det samme.
Virker ikke, gå langt udenom.

Vi beklager, at Deres oplevelse med EMI2500-modellen ikke har levet op til Deres forventninger.

Dropson-afkalkningssystemet fjerner ikke kalken fra vandet, men omdanner den fysisk til ikke-tilsÊttende mikrokristaller, som ikke aflejres i installationer eller indvendige mekanismer.

Det er en forebyggende behandling, fordi den forhindrer dannelsen af nye kalkaflejringer i rÞr, varmevekslere og varmeelementer.

Det virker også helbredende, da det gradvist hjÊlper med at oplÞse eksisterende kalkaflejringer og letter deres bortledning gennem aflÞbet.

Det er normalt, at der fortsat kan opstå lette hvide mÊrker på overflader (såsom drikkeskåle eller armaturer), men disse er ikke egentlige aflejringer og kan let rengÞres.
Den store forskel ligger i, at kalken ikke ophobes inde i systemet, hvilket forbedrer energieffektiviteten og reducerer risikoen for skader på lang sigt.

Hvis De Þnsker det, kan vi gennemgå Deres sag for at sikre, at det anvendte udstyr er korrekt dimensioneret til Deres installation og vandforhold.
De er meget velkommen til at kontakte os på  comercial@dropson.es

Tak fordi De har valgt Dropson.

Dropson EMI 4000
Hårdt vand på Vestfyn, har haft den godt et halvt år.
Den Þjeblikkelige effekt sås et sted jeg ikke havde forventet, nemlig hårvasken! Helt anderledes let og blÞdt hår, og ikke så tÞr hud. Synlig effekt på lidt lÊngere sigt, at kattens vandskål ikke får kalkrande, men forbliver stålblank.
Vigtig vejledning fra installatÞren, ikke nÞjes med model 2500, da den kun har kapacitet til en enkelt installation som fx en vaskemaskine. Og model 4000 var kun få 100 kr dyrere.

Det virker overhovedet ikke.
0 effekt, simpelthen.
installerede den i januar og i samme omgang blev alle vandhaner skiftet, brusere, vaske og toiletter totalt afkalket.
Nu er alt dog ved det gamle, hvidt OVER ALT!
Der krÊves også nÞjagtig samme mÊngde knofedt og kemikalier for holde det nede.
Ved ikke om det er vores Frederikshavner vand eller der er tale om et fup produkt her.
Det er et par måneder siden jeg lagde mÊrke til den manglende forskel men er fÞrst nu sur nok til at skrive en trustpilot anmeldelse.

KÊre Mads,

Vi beklager oprigtigt, at Deres oplevelse med Dropson EMI 2500 ikke har levet op til Deres forventninger.

Dropson-systemet fjerner ikke kalken fra vandet, men omdanner de mineraler, der forÃ¥rsager kalk, til ikke-tilsÊttende mikrokristaller. Dette forhindrer, at kalken sÊtter sig fast i installationer. Det er en fysisk og ikke-kemisk behandling, og effekten ses primÊrt i den indvendige beskyttelse af rÞr, varmevekslere og husholdningsapparater – hvilket pÃ¥ sigt reducerer risikoen for skader og forbedrer energieffektiviteten.

Det er vigtigt at nÊvne, at hvide mÊrker pÃ¥ ydre overflader (armaturer, vaske, brusere) stadig kan forekomme. Disse er dog ikke egentlige kalkaflejringer, men snarere ikke-tilsÊttende rester, der let kan fjernes – ligesom med regnvand med hÞjt mineralindhold.

Vi forstår Deres frustration og vil gerne gennemgå Deres sag for at sikre, at anlÊgget er korrekt dimensioneret, og at installationsbetingelserne (såsom minimum flow og lokal vandhårdhed) er opfyldt for optimal drift.

De er meget velkommen til at kontakte os på 📧 comercial@dropson.es
, så vi kan yde personlig support.

Tak fordi De delte Deres oplevelse – det hjÊlper os med at blive bedre.
