Introduction of a series of water heat exchangers in a design housing with an output of between 1 and 10 kW for medical and laboratory applications.



Acquisition of Duotemp Kältetechnik GmbH. Up until 2006 the company was headquartered in Holzgerlingen, near Stuttgart. Duotemp Kältetechnik GmbH can look back upon over 30 years' experience in the field of industrial refrigeration. By concentrating increasingly over the years on the areas of workpiece cooling, process cooling and vapor condensation, Duotemp Kältetechnik GmbH has established itself in the international market. The merger of these two companies was a key milestone in the corporate development. Accelerated growth, access to new markets, or the acquisition of know-how, all bred synergies that benefit our customers.
