1986
Dipl.-Ing. Dean Kronsbein initiates the next strategic goal and founds ultratrockner Energietechnik GmbH, Haan, with the objective to develop and produce innovative adsorption dryers. These innovative drying systems reduce the energy consumption by 50%. At the heart of the adsorption dryer is the self-adjusting load dependent control. ultratrockner Energietechnik GmbH is the first company in the world to combine adsorption dryer, pre- and afterfilter in a compact cabinet design. During the following years ultratrockner Energietechnik GmbH becomes the leading international manufacturer of compressed air adsorption dryers.

1993
To satisfy the rising demand for absolute clean, dry and oil free compressed air, Dipl.-Ing. Dean Kronsbein develops the oilfreepac. With this system, even oil-injected compressors produce a better compressed air quality than oil free operating compressors, with the added value of lower operating costs.

In addition to innovative products the previous company offers a comprehensive service package. More than 60 qualified service technicians provided compressed air services close to their customers.

1999
Dipl.-Ing. Dean Kronsbein is nominated as Entrepreneur of the Year out of 3000 industrial companies.

2001
Dipl.-Ing. Dean Kronsbein founds Ultra.air GmbH as a provider of energy optimised compressed air solutions to the industry. An exclusive agreement with EON to market the new product EON-Ultra.air is concluded.

2006
With the growing demand for reducing the energy costs of compressed air, the newly founded Ultrafilter GmbH develops high efficiency filter elements using nano-technology, which require a 70 % lower energy consumption.

2007
The new Ultrafilter housings with modular connections are introduced at the Hannover Fair 2007.

March 2007
Dipl.-Ing. Dean Kronsbein took over the Ultrafilter GmbH, founded in 2006, after leaving Donaldson Filtration GmbH.

The company builds a new research and production centre in Hilden at the beginning of the year. It offers optimised working conditions and prospects to all employees.

At the grand opening, managing director Dipl.-Ing. Dean Kronsbein says: “We will introduce more innovative product solutions for our customers than ever before.”

March 2008
Ultrafilter GmbH takes over the energy and compressed air consultant group Ultra.air. With this integration, Ultrafilter offers their customers the opportunity to participate in and benefit from the Ultra.air competence in all aspects of compressed air (from the source of energy to the point of use).

Ultrafilter GmbH is a family owned company, managed by Dipl.-Ing. Dean Kronsbein.
