About WT Wärmeaustausch Technologien AG
WT Wärmeaustausch Technologien AG was founded in 2004 by brothers Marcel and Hugo Broch and is located in Giffers in the Canton of Fribourg. The company specializes in the sales, manufacturing, servicing, and maintenance of plate, tube, air, and special heat exchangers, as well as solutions for system separation. The portfolio includes bolted and gasketed plate heat exchangers, vacuum-brazed heat exchangers, spiral tube and tube bundle heat exchangers, fin-air heat exchangers, as well as coolers and evaporators. Manufacturing and assembly are done using stainless steel (including 1.4301, 1.4401), copper, copper-nickel, steel, and aluminum; brazed heat exchangers are manufactured using copper, nickel, or stainless steel solder in a vacuum process. The heat exchangers are used, among other applications, in building technology, chemical industry, process technology, food industry, district heating, climate/refrigeration technology, power plant, and environmental technology. All manufactured plate heat exchangers undergo a leak test before delivery; extensive stock enables short delivery times.
