The 1930s

EUROWATER was founded in 1936 in Denmark when three Jutlandic dairy engine works
decided to establish a common water treatment company instead of each having one.
Th. Nansen Scherfig was appointed managing director.

The company started out modestly in an apartment in the city of Aarhus and the focus was laid on customers such as smaller waterworks, farms, and coin laundries. The first year, the company became sole agent of a deacidification substance called Magno. This substance has been used ever since. At the same time, Th. Nansen Scherfig developed his filtration plant, the NS plant.

The 1940s

At the beginning of World War II, EUROWATER moved to a large house in another part of the city of Aarhus. The fleet of cars consisted of only one service car; an old-fashioned Chevrolet with a gas generator. This car delivered plants for waterworks all over Jutland. After the war, the business had better conditions which was celebrated with an ad in a large, Danish newspaper in May 1945. The ad describes the company’s competencies from water analysis and consultancy to installation of a complete water treatment plant.

The 1960s

In 1960, the 16 employees moved to new premisis. New offices, a regeneration establishment, and an assembly shop had been built. The large-scale building of 830 m2 was prepared for the industrial development. In 1963, Th. Nansen Scherfig established contact with the American company Water Refining in Ohio which wanted to gain a footing in the European market. Thus, the export company EUROWATER consisted of half American and half Danish share capital. This was the chance to automatize the softening plants. The automation of the softening plants led to an expansion outside of Jutland due to an increase of laundrettes. An area office was then opened on the island of Sealand. EUROWATER also expanded into Germany with offices in Hamburg and Mannheim.

The 1970s

With the oil crisis at the beginning of the 1970s, economic activities slowed down. However, EUROWATER could present an automatic demineralization plant which was especially important on the export markets. In the middle of the decade, EUROWATER bought the American shares in EUROWATER, and thus, the export company was again 100% owned by Danes. At the same time, EUROWATER offices were established in Sweden and Belgium.

The 1980s

In the 1980s, EUROWATER gained a stable position in the export markets, and approximately 75% of the production left Denmark through direct or indirect export. The plant modules grew larger and were furnished with fully electronic control units. At the 50 year’s jubilee in 1986, a newly developed plant based on reverse osmosis was introduced. In 1988, the German branch extended with an office in Augsburg and the Swedish branch established another office.

The 1990s

The 1990s were the decade of expansion! In the beginning of the decade, companies were established in Czechoslovakia, which was later divided. In 1993, EUROWATER established companies in both the Czech Republic and Slovakia. In 1992, a subsidiary was established in Austria and the following year in Poland. Later on, EUROWATER entered into a 50% partnership with a company in Gdansk and in 1996 another branch was established in Germany. EUROWATER became at the same time a 50% partner of a factory which produces filter tanks, Botax Eurotank Aps. A company in the Netherlands followed in 1998.


Botax Eurotank ApS was in 2000 renamed the current Eurotank A/S and was also turned into a private limited company owned 100% by Silhorko-Eurowater A/S.


Until 2003, the Scherfig family had been the sole owner of Silhorko-Eurowater A/S. But in 2003, the ownership was divided between Erik Nansen Scherfig, Harry Viiala, Kurt Hufnagl, and Torben Buhl. Erik Nansen Scherfig is the former owner and managing director in Silhorko-Eurowater A/S, while Harry Viiala is the owner and managing director in the Finnish company HyXo Oy which is a EUROWATER dealer in Finland. The daily management is carried out by Kurt Hufnagl and Torben Buhl. In 2003, the sale of nanofiltration plants started.


In 2005, the expansion of the export markets continued, and subsidiaries were established in Norway and France. The EDI plant was launched which, as the nanofiltration plant, was met with a favourable reception in the export markets.


The sales of water treatment plants was record high in 2007. The total sales of the group reached approximately 3.79 mio. Euros – which was almost 15% more than the year before. The positive development and trend are prevailing in both the EUROWATER companies as well as in many of our dealers. In the wake of this success, we have extended the production capacity at the factory in Stilling which has been a necessary part of still being able to offer our customers short and reliable delivery times. In the middle of 2007, another subsidiary was established in Hungary. At the end of the year, EUROWATER was certified to sell water treatment plants for boiler water installations in Belarus.


Silhorko-Eurowater A/S employees 240 people, half of which are based in Denmark at the head office and factory and the other half at the sales and service office on Sealand and at the factory Eurotank A/S. The rest of the employees are working in the EUROWATER offices all over Europe.

Technologies as well as customer needs change. As part of a continuous product development, EUROWATER is working on introducing a customized series of flexible control systems with built-in operator panel and programmable logic controller (PLC) to support our broadproduct range.

2008 was the year in which a subsidiary in Kiev in the Ukraine was established.


75 years of experience in water treatment.


In 2014, the expansion of the export markets has continued, and new Eurowater offices have opened in Hudiksvall in Sweden and in Gdansk in Poland.

Silhorko-Eurowater A/S now employees 340 people, half of which are based in Denmark and the rest of the employees are working in our 23 EUROWATER offices all over Europe.
