About 79gradminus
79gradminus is a company specialized in industrial cleaning and disinfection, based in Berlin with a workshop in Krefeld. The service portfolio includes hybrid cleaning of electronic systems and machinery, dry ice blasting, sandblasting, steam cleaning, chemical cleaning, mold remediation and disinfection measures, including air disinfection of armored wheeled and tracked vehicles and air conditioning disinfection of public transport vehicles. The cleaned objects range from control cabinets, switchgear and sub-distribution boards to radar equipment and weapon systems, as well as blast furnaces, crane components and ship and aircraft parts made of aluminium, steel and armor steel. References include the cleaning of a complete Siemens ICE prototype, blasting work on an industrial plant with more than 300 meters of conveyor line and a 200-ton press, and the multi-year development of a disinfection process for the German Armed Forces (Bundeswehr). For BASF/Henkel, a process was developed for preparing ultrasonic crack testing of weld seams. The mobile service is available on request every day throughout Germany within 24 hours; equipment rental is also offered.
