About TLT-Turbo
TLT-Turbo GmbH, headquartered in Zweibrücken, develops and manufactures industrial axial and centrifugal fans as well as complete ventilation systems for demanding applications. The portfolio includes power plant fans with volume flows exceeding 1,000 m³/s and pressure increases of up to 20,000 Pa, mine and tunnel fans, industrial fans, wind tunnel fans and turbo fans for mechanical vapor recompression (MVR). Manufacturing covers fusion welding of metallic materials, load-bearing steel structure components and pressure equipment components, complemented by assembly, commissioning and service. An in-house materials laboratory conducts corrosion and wear testing as well as service life tests. Core markets are mining, tunnel and metro, power generation, process industry, food and beverage industry as well as pharmaceuticals. The company was founded in 1827 as Dinglerwerke, has been part of the PowerChina Group since 2014 and supplies projects on six continents.
