About Kühner Wärmetauscher
Kühner Wärmetauscher GmbH & Co. KG is a third-generation family company based in Korntal-Münchingen near Stuttgart. The company develops and manufactures custom-made heat exchangers, including air heaters, air coolers, exhaust gas heat exchangers, return coolers, finned-tube, plate-fin and plain-tube heat exchangers as well as special and replacement units. Each product is designed in close consultation with the customer on the basis of proven technical modules; according to the company, it takes at most one to two working days from enquiry to an individual solution. Products are made from stainless steel, hot-dip galvanized steel, aluminium, copper and titanium; steel heat exchangers are hot-dip galvanized in a full-immersion bath. The products are used, among other things, in ventilation technology, air conditioning systems, drying ovens and process engineering applications; media include steam, thermal oil, water, gas, air, exhaust air and exhaust gas. In 2020, 250 tonnes of steel were processed and 148,000 tubes welded; since 2017 an automated production line has been available.

Materials and Processes
Steel, hot-dip galvanized
Full-immersion hot-dip galvanized steel heat exchangers offer economical corrosion protection when copper is no longer sufficient and stainless steel is not yet necessary.
Stainless steel
For applications with high demands on temperature and corrosion resistance.
Aluminium
Material for fins and tube versions in heat exchangers.
Copper
Proven tube material for heat exchangers with good thermal conductivity.
Titanium
For demanding, corrosion-critical media and applications.
