About STS-TankService
STS-TankService GmbH is a medium-sized company in energy technology specializing in tank cleaning, tank protection, tank and industrial plant construction, as well as service, maintenance, and upkeep. What started in 2000 with tank cleaning in Berlin and Göttingen has developed into a comprehensive portfolio through strategic acquisitions: planning and engineering, construction and installation of tank and piping systems, corrosion and leak protection using epoxy resin base slabs and tank protection inner linings, modernization, dismantling, and disposal, as well as the distribution, design, and repair of flame arresters, breathing valves, and valves. Work is done with steel, stainless steel, and plastic; testing is performed through tightness, pressure, and wall thickness measurements as well as test bench tests. Customers come from petrochemical, process and chemical industries, energy and power plant facilities, renewable energies, as well as airports and gas stations. In addition to Germany, the company executes projects in Austria, Switzerland, France, Sweden, and Poland with around 80 employees.
