Lousy climate without HX-Factor


Consider the cooling and heating in processing industries, power plant engineering and HVAC requirements of our advanced society, and you’ll quickly discover how much we have come to rely on high quality heat exchangers. Take for instance the supply of district heat, in which large heat exchangers input energy from power plant heat processes into urban heating networks – and implement the required energy transfer to residential heating cycles. Good for people and good for the environment.

District heating

Our heat exchangers – plate heat exchangers and shell and tube heat exchangers – are employed in the supply of district heating, which link heating supply from power plants via transfer stations to the final user. These heat exchangers are, for example, also applied in geothermal engineering, solar-system separation, floor heating, and district cooling. Compact system design and clarity in investment calculation mean a maximum of heat-transfer rates.

Heating and cooling for quality of everyday life

Shopping centers, supermarkets, caterers, and cold storage warehouses require powerful and, above all, efficient refrigeration technology – since these systems represent the largest operating-cost factor in refrigerated warehousing. Reliable finned tube heat exchangers for refrigeration assure that the ecological footprint of the cold chain remains at a minimum and that consumers can enjoy an extensive offering of fresh fruit and vegetables, cold drinks, and ready-to-eat meals. These benefits are made possible by optimal, reliable supply of chilling and freezing.

Those who enjoy spending their leisure time in indoor ski centers usually care very little about seeing or hearing the mechanical systems that make their enjoyment possible. This is why our finned tube heat exchangers for refrigeration in indoor skiing are designed to work discreetly in the background. For the same reason, our wet cooling towers, with their modular design, are used in especially large building complexes such as airports and factories. These systems can be especially planned to be installed where they are unseen and unheard.

The London Underground subway system places great importance on the comfort of its patrons – beginning with their wait on the station platforms. Our refrigeration heat exchangers above the platforms operate with ground water and assure pleasantly cool temperatures in underground stations.


Thanks to the highly compact design of our cooling systems – owing to their innovative fin geometry – they have set new standards in the transport business for space requirements, weight, and use of material. In engines, the charge air, in addition to the fuel, is a key factor for efficient combustion. Around the world, finned tube heat exchangers from us increase the efficiency of diesel engines in locomotives for freight and passenger trains, as well as for heavy-haul trucks on the road. In addition, shell-and-tube heat exchangers cool transformer oil in electric locomotives and in other railway traction units.


In industrial production plants, heat exchangers can be found in operation everywhere. In many cases, heat exchangers are absolutely essential for the operation of electrical motors, internal-combustion engines, cogen power plants, and air treatment facilities. They are elementary constituents of any and all process engineering plants. The ecological footprint of an entire complex is not least determined by the efficiency of their heat exchangers. Greater efficiency of an refrigeration heat exchanger signifies reduced space and lower energy consumption. In comparison with systems with water as cooling medium, air cooling offers yet another positive side effect: it conserves water resources and prevents the heating of natural bodies of water. We are pioneers here and are leading in the world in the field of industrial air cooling.

For years now, the factors economy and ecology have no longer been inimical: indeed, with our heat exchangers, they go hand in hand. We must conserve our finite resources, and rising raw-materials costs mean that reduced consumption also conserves the bank accounts of consumers.
