HomeAbout usHistory History

Whether in the kitchen, bathroom, or shower – Neoperl is involved almost everywhere that drinking water is used. You will probably come into contact with Neoperl products several times a day without even realizing it. The origins of our company, which today operates worldwide, go back more than 60 years and are rooted in Germany and Switzerland.

"Hans Denzler & Co" in Reinach-Basel, Switzerland (today Neoperl AG).

1959: Foundation in Switzerland

Albert Wildfang and Hans Denzler recognize the potential of faucet aerators. In 1959 in Reinach-Basel, Switzerland, they establish "Hans Denzler & Co" – trading nowadays as Neoperl AG.

Neoperl is the first neutral manufacturer to install and distribute › faucet aerators in Switzerland. The NEOPERL brand establishes itself in the retail business and, thanks to the built-in screen, becomes known for a splash-free water stream – previously unheard of at that time.

In 1961, Hans Denzler and Albert Wildfang, together with the latter's son Dieter, set up "Dieter Wildfang KG" in Müllheim, Germany – trading nowadays as Neoperl GmbH. Soon afterwards, they start production of faucet aerators in their own factory and expand their business to industrial customers.

From the very beginning, Neoperl has relied on a concept that is forward-thinking to this day: a low vertical range of manufacture. This means that the company procures the required individual parts from specialized partners and assembles them into finished products. Neoperl can therefore concentrate on the development and marketing of its products.

1970s: Expansion of the product range

In the course of the 1970s, Neoperl continues to develop the faucet aerator, continuously expands production, and taps into the German and later the European market.

Following intensive development work, the company is the first manufacturer to bring low-noise faucet aerators onto the market. The success of the product leads to a sharp increase in production quantities.

It is therefore time to automate production. Neoperl also adds › check valves to its product range.

The focus is now on research and in addition to the flow regulator, the first water-saving aerator with integrated flow regulator is developed.

1980s and 90s: International growth

Neoperl is now a sought-after expert on all matters of drinking water and forges ahead with the internationalization of its industrial business.

In 1987 the company takes over the American manufacturer Waterbury Pressed Metal. Neoperl expands the site to create its first production and distribution company outside Europe, and gradually gains a foothold in the USA and Asian markets.

In the 80s, environmental and climate protection also come into the public eye for the first time. In response, the Neoperl Group concentrates its research on › water saving products.

The company develops › flow regulators and launches the first water saving faucet aerators with integrated flow regulators. In 1994 it takes over R. C. Mannesmann, the strongest competitor in this field.

The Neoperl Group focuses more and more on its core competencies: research and development, assembly and production, logistics and sales.

In addition, Neoperl spins off the local retail business for plumbing products in Switzerland, and builds up its own sales organization to supply German specialist merchants directly.

2000s: Leading research and development

In the new millennium, first class faucet design gains in importance. In order to develop the necessary innovations, the company opens a state of the art research and development center in Müllheim.

Step by step, the Neoperl Group also expands its international distribution network with its own agencies and production sites, especially in the Asian markets. The European retail business starts being handled from Switzerland.

In 2004, management of the family business passes to the next generation. From this point onwards, Oliver Denzler and Fabian Wildfang shape the future of the Neoperl Group.
