Herbst Technik has started in 1969 as R&D of Herbst AG, a company founded by Dr. Walter Herbst shortly after the Second World War, specialising in the planning and construction of heating and air conditioning systems and evolved to become one of the large supra-regional Heating and Ventilation companies in Germany, with over 800 employees, until it was sold in 1990 following the fall of the Berlin Wall, when it merged into a larger network.

Focusing on research and development Herbst Technik conducted original research into energy saving products and climatisation technology systems under the direction of Donald Herbst. For example, in 1975 he introduced the use of heat recovery and variable air  volume for air handling units; in 1978 Herbst Technik  incorporated a digital controller system for air conditioning plants. The department expanded to include environmental technology with projects such as the desulphurisation of central heating boilers and the purification of contaminated soil and water.

In 1990, with the sale of Dr. Walter Herbst AG, Herbst Technik GmbH has been run as a independent company. With the invention of the capillary tube cooling ceiling (1982) development has concentrated more and more on katube technology. Since then, fully automated production machines for the fabrication of capillary tube mats have been developed, in addition to precise dew point sensors for cooling ceilings, which are established today generally for radiant cooling. In 1985 flexible water cables with CC-couplers brought considerable relief to the assembly of cooling ceilings; in 2004 the introduction of thermo foil technology increased the efficiency of katube boards.

The latest development is the inline UltraWelding in production machines for capillary tube  tube mats and the new katube mat based on cross-linked capillary tubes for high efficiency heat recovery exchangers in air conditioning units.
