The challenge
Around the globe, banknotes of almost all currencies are secured against counterfeiting with security strips and holograms. Security features, which require high precision manufacturing. Georg Sahm GmbH & Co. KG, headquartered in Eschwege, Germany, is a world-wide technology leader in the field of automatic precision winders for high-performance fibers. This challenging area usually requires customized solutions in control cabinet construction. For Georg Sahm Maschinenfabrik, short development times and clearly defined budgets together with häwa's comprehensive know-how play a significant role.
häwa received an order for a specific customized solution for the winding technology which is required for the banknote printing process. Special features require a sophisticated technology of the machines, developed and provided by Georg Sahm. This technology ensures the precise insertion of security strips in the future banknotes. The control cabinet must meet extremely high requirements regarding cooling and tightness, high humidity and excessive temperature as well as aggressive chemicals in the ambient air during the manufacturing process.
häwa solution
The cabinet had to be made of stainless steel, with a height of 2,000 millimeters plus a 100-millimeter-high base, a width of 800 millimeters and a depth of 600 millimeters. A cooling unit also had to be integrated. Based on the standard cabinet type H370, whose protection rating was increased to IP65 by adapting the locking system and seal, häwa finally designed a customized cabinet made of stainless steel V4A, with a lateral operation terminal, covered with a swing protective hood.
The door is equipped with a cooling unit type KF1200. häwa determined the required power consumption of the cooling unit in advance. The cooling unit is covered with a protective hood, which ensures the separation of the air circuits (air inlet/outlet) and thereby allowing the use of a non-filter cooling unit.
The technical features were optimized in joint project work before häwa submitted a detailed offer. Based on the standard stainless steel cabinet type H370, whose protection rating was increased to IP65 by adapting the locking system and seal, häwa finally designed a customized cabinet, which has meanwhile been delivered several times. The non-filter cooling unit, mounted at the front door provides the required temperature. Result: a customized solution that meets the highest standards, ensuring that people all over the world can make their purchases with counterfeit-proof banknotes.
