Siemens as the world leader in the automation technology is forced to their products up-to-date. This is the reason why the renovation of existing products gets quicker and quicker. The manufacturer needs to sell and establish new products in the market to replace the obsolete products. Very often that is not possible because of prices or to technical reasons. SINTRONICS is your partner who either repairs your used components or who replaces the obsolete products from their own stock.
