production local presence The Production of SCHAEFER designed Products takes place in the primary Production Facility in Germany, as well as the second Production facility in Ireland. Both factories having redundant capabilities allow for an additional chain of supply for Products through separate Stockroom, Personnel etc, thus removing the dependence on a single source and guaranteeing integrity of Production. Following through on decades of design and technical support, SCHAEFER GmbH is increasingly being asked to support locally through distributors and strategic partners as well as wholly owned and operated SCHAEFER subsidiaries and sub offices. To this end, SCHAEFER GmbH Germany, SCHAEFER Inc and SCHAEFER GmbH Middle East have seen an increasing supporting role for Projects manufactured in Germany, but with the value added support and management locally. The following are some key items where SCHAEFER has been active: Assistance in the extrapolation of information from the design criteria Design proposal tailored to the specifications Manufacture and complete Production Management for the Scope of Works allocated to SCHAEFER Logistic support Type Test Certification Factory Acceptance Testing (FAT) / First Article Inspection (FAI) Training the Client s personnel in the optimum use of the SCHAEFER equipment Commissioning on Site 3

Company profile Quality management workforce experience flexibility client orientation SCHAEFER GmbH, established in 1969 by Dr Johannes Schaefer, is a wholly owned, privately run company, assisted by a qualified, and experienced, team of experts, SCHAEFER has grown in a controlled and sustainable manner to a dedicated workforce of over 200 people, who oversee the entire concept, design, control and manufacture of all of the SCHAEFER Product Portfolio. Stemming from experience which dates back to the founding days of the Company, SCHAEFER Personnel can tap into a rich resource, that is our Intellectual Property, which can only be gained from Designing, Manufacturing solutions after detailed and in-depth consultation with Clients. It is as a result of this intensive depth of Engineering that the Product Portfolio has been expanded to include: THYRISTOR Controlled Power Supplies & Battery Chargers DC / DC Converters AC / DC Rectifiers & Battery Chargers DC / AC Inverters single & three phase AC / AC Frequency Converters single & three phase Electronic By-pass switches DC & AC, UPS systems Control and monitoring systems integrated and stand alone Maintaining the ability to design in house & manufacture in house generates a large degree of flexibility. The SCHAEFER Client profits from these engineering skills through an optimised solution tailored to the needs and parameters of the Project. Immediate proximity also generates the free flowing information path, which is the production and development areas, along with the testing and customer support areas being all under the same roof. This enhances the SCHAEFER team s ability to react to exacting demands with ease. Fruits of this labour are to be seen throughout the World, in a variety of fields such as: Rail industry Automotive industry Telecommunication Industry Power Generation Industry Chemical industry Oil & Gas Industry Factory Industry Military Industry Aeronautics Industry Be they on shore or off shore, stationary or mobile, land air or marine based, a system component or complete system, environmentally Hazardous Area 1, corrosive or simply Industrial, there is a SCHAEFER Power solution to fit the parameters.
