Over the last few months several companies in the aircraft and aerospace industry have opted to invest in cleaning systems from Dürr Ecoclean GmbH. Among them were companies belonging to the French Safran Group and their suppliers. The core competencies of the globally-acting group of companies include drives for the aircraft and aerospace market, airplane equipment, safety and defense systems as well as information and telecommunication systems. The ranges commissioned comprise cleaning systems using non-halogenated hydrocarbon (HC), perchloro-ethylene (CHC) and MPC cleaners. The majority of systems were custom-ized in line with the applications in place at the various companies.
Cooperation already started some years ago with the delivery of a hydro-carbon cleaning system for cleaning landing systems. The presently or-dered HC cleaning system of the Special 95C model will be used for cleaning turbine components of helicopters. The requirement that particles must not exceed > 100 µm demands that high standards of cleanliness are met. In addition the cleaned parts also need to be preserved. These demands are fulfilled by using one chamber for the cleaning process and one for the preserving process, three surge containers, ultrasonics and fine filtration with cartridge filters.
The CHC systems of the Special 71S model are used for removing oil, shavings and emulsions from turbine and engine components. To achieve the required cleanliness of parts the systems are equipped with two surge containers, ultrasonic devices and a media processing unit with cartridge filters.
The Special 71WZ cleaning system cleans turbine components for rock-ets. Dürr Ecoclean has developed this new system concept combining the advantages of aqueous tenside systems and of solvents for using MPC cleaners from the cleaning media manufacturer Zestron. MPC cleaners are
a mixture of water and highly active cleaning substances for the precision cleaning of metal parts. The entire cleaning process is carried out with one medium -- rinsing cycles needed for solvent cleaning are not required. Through thermal effects and/or agitation, MPC cleaners form so-called MPC phases which remove different types of soiling such as non-polar oils and greases, polar emulsions and saline contamination in a single clean-ing operation. With this process, degrees of surface cleanliness of up to >50 mN/m are achieved.
Ratier-Figeac also relies on the quality and experience of Dürr Ecoclean when it comes to cleaning their components. The company based in Figeac, France, produces various components for helicopter and airplane manufacturers such as Airbus. Ratier-Figeac has decided to purchase five cleaning systems from Filderstadt. Some of them have been customized to their specific application.
Prior to placing the orders, extensive cleanings tests were carried out in the pilot plant stations of the system manufacturer, both for the companies of the Safran Group as well as for Ratier-Figeac. In addition to its convinc-ing cleaning quality, the robust, low-maintenance design and the price/performance ratio of the cleaning systems tipped the scale in favour of Dürr Ecoclean. With these orders, the system manufacturer from Filder-stadt is not only consolidating its position in the aircraft and aerospace industry, but is also underlining Dürr Ecoclean's technological leadership in the international market.
