Wangener Haustechnik GmbH & Co. KG

What Wangener Haustechnik GmbH & Co. KG does

Wangener Haustechnik GmbH & Co. KG (WHT) is a privately held German skilled-trades company (Handwerk) registered as a Kommanditgesellschaft in Wangen im Allgäu, Baden-Württemberg. The company in its current legal form was established in 2006, with operational roots traced to a 1908 sheet-metal workshop (Flaschnerei) founded by Hermann Waldner. Since 28 March 2025, WHT has operated as a 100% subsidiary of Franz Lohr GmbH Ravensburg, within the broader Franz Lohr Gruppe; both companies continue to operate independently under their own brand names.

WHT provides integrated, project-based technical building services spanning industrial facade engineering, roof and structural waterproofing, sheet-metal fabrication and Klempnertechnik, metal and plant construction, heating, sanitary, ventilation and air conditioning, refrigeration, and electrical engineering. Core technical capabilities include sheet-metal processing, WIG/MAG welding certified to EN 1090-2:2018, prefabricated pipework in the Kempten workshop, district-heating and stainless-steel process piping, building automation via Modbus, heat-pump heating with heat recovery, photovoltaic integration, and industrial facade construction in aluminium, coated steel, titanium zinc, copper and stainless steel. Delivery runs from planning through in-house fabrication to on-site assembly.

The business operates on a B2B project model with direct enterprise field sales targeting industrial, commercial, healthcare and public-sector clients across Allgäu, Oberschwaben and the Bodensee region in southern Germany. Revenue is generated primarily through one-time construction and installation projects, supplemented by custom in-house fabrication (hardware sales) and recurring maintenance and service contracts. Customers include the Bodensee-Therme Überlingen, Waldburg-Zeil Kliniken, Hofgut FARNY, Käserei Champignon Hofmeister, the Münsterschatzkammer Reichenau (UNESCO World Heritage), Beller, Biedenkapp Stahlbau, Lufti Kinderspielewelt and NL Zerspanungszentrum. Certifications include Schweißzertifikat EN 1090-2:2018, DVS Zertifikat, and recognised Ausbildungsbetrieb status across five trades. Note: the firm's listed headcount of 5 appears inconsistent with the disclosed project scale and likely understates core technical staff.
