Heat exchangers are used to cool or heat liquids and/or gases. This is possible with or without a phase change.

Design and construction follow the international TEMA standard (Tubular Exchanger Manufacturers Association). We create apparatus in a wide range of variations, always taking into account the individual wishes of our customers. For planning and execution, we use powerful software programs such as HTRI or ASPEN, as well as computer programs developed by ourselves, which on the one hand guarantee the design data of our products and on the other enable the rapid processing of customer enquiries.


A high vertical range of manufacture as well as modern facilities enable us to execute orders with great flexibility within the scope of the following sizes and weights.

  • Diameter up to 5,000 mm

  • Length up to 30 m

  • Total weight up to 150 t

  • Operating pressure up to 1,000 bar
