Our company was founded in 1968 by Peter Huber as one of the first master companies in the refrigeration engineering trade and has been family-owned ever since. In 2016, the legal form was changed to a stock corporation. At our headquarters in Offenburg, the Tango factory, we currently employ over 420 people. In addition, with international subsidiaries and sales partners, we offer a worldwide network for consulting, sales and service.

With numerous product innovations, we have driven technological development in the field of fluid temperature control. The introduction of Unistat temperature control systems in 1989 was a revolution in temperature control technology, and to this day Unistats set the tone when it comes to highly dynamic temperature control processes.

We are a leading supplier of high-precision temperature control solutions for research and industry. Worldwide, our products ensure precise temperature control in laboratories, pilot plants and production processes. Our product range offers innovative solutions for almost all tasks in the field of liquid temperature control from -125 to +425 °C. One focus of our product portfolio is the dynamic temperature control systems of the Unistat series. In addition, we develop and produce circulators as well as classic heating and cooling thermostats. For numerous applications in the automotive, chemical, pharmaceutical, aerospace, semiconductor and biotechnology industries, we supply customized special equipment, which is realized in close cooperation with our customers.

As a pioneer in refrigeration technology we have been using hydrocarbons in our products for many years. Already in the early 1970s, company founder Peter Huber started researching and using natural refrigerants. In the following years, Propane and Propene have been used as a standard refrigerant in many units.

In practice, natural refrigerants have significant advantages over their synthetic derivatives, e.g. very good thermodynamic properties. Advantages include low pressure losses in pipelines and heat exchangers, low energy consumption during compression, lower amounts of refrigerant required and good material compatibility.

Unistat • Tango • Grande Fleur • Petite Fleur with natural refrigerants
For more than 30 years, the dynamic thermoregulation of the Unistat range introduced a revolution in fluid temperature control. Unistats are the ideal solution for fast and precise thermal control of externally connected applications. In comparison to other circulators, the Unistats offer rapid temperature change and a wide temperature range without fluid change. There are over 60 models to choose from with cooling powers from 0,7 to 130 kW. What ever the application, Unistats provide professional scale-up offering the same stable process conditions from the development lab to production systems.
