Messer supplies Technov Rumanova with liquid nitrogen in a cryogenic tank as well as oxygen 3.5 and welding gases for the production of ventilation and air conditioning systems, which have seen a massive boom in demand in recent years. Technov, one of the leading suppliers in Europe, possesses the hygiene certificate issued by the ILH air hygiene institute in Berlin.
