History
In 1962 S. H. Anderson introduced the first hydraulic demonstration channel while a Research Fellow at the University of Minnesota's St. Anthony Falls Hydraulics Laboratory. While teaching, he recognized the need for quality laboratory equipment which would demonstrate the basics of civil engineering hydraulics and provide the student with a springboard for more in depth investigations. To facilitate the manufacture of this equipment, he established Hydraulic Design & Products Co. from his residence in a Minneapolis suburb.

The product line soon expanded to include other proprietary design student laboratory apparatus and related equipment for aeronautical, chemical, civil and mechanical engineering institutions. To reflect these changes the company was renamed and incorporated in 1966 under the name Engineering Laboratory Design. The first wind tunnel was manufactured in 1968 and the first water tunnel in 1986.

In 1972 ELD moved from our original facility in Golden Valley, Minnesota to our present location. While the original product line continues, the company has developed additional educational and research apparatus and contracted larger, custom designed, laboratory projects for institutions in the U.S.A and overseas, thus expanding ELD's manufacturing capabilities, products, and services worldwide. ELD Inc. is currently owned by Sigurd W. Anderson, Gordon K.Anderson, and Kurt A. Banaszynski.

Engineering Resources
Our engineering staff is comprised of engineers with degrees in aerospace and mechanical fields and extensive experience in civil engineering hydraulics. We are experienced in fluid mechanics, composites and traditional structures, mechanisms, hydraulics, pneumatics, instrumentation and data acquisition, electrical controls and various molding methods. Computer aided design is used to accelerate the design process and analysis of simple and complex projects. Our engineers are involved in all stages of product development, from initial concept, through design, manufacturing and installation. This hands on approach allows our designs to continually evolve whereby simplifying the manufacturing process and reducing costs.

Manufacturing Resources
ELD's manufacturing expertise covers a wide variety of materials, methods and techniques. Our manufacturing capabilities include construction of wood and composite molds and tooling, precision machining, sheet metal forming, MIG and TIG welding and electrical assemblies. We are experienced in precision molding of fiberglass shapes including PVC foam sandwich construction and carbon fiber reinforcements. Our skilled craftsmen are cross-trained in all work centers which allows for greater efficiency and flexibility.

Quality Product
Quality is our first concern. At ELD quality is a core discipline which transcends through all company procedures from initial customer contact to design, manufacture, installation and after sale support. Quality is a philosophy to which all employees subscribe.

Computer Resources
A PC based hardware and software platform is used to augment both our engineering and manufacturing capabilities. AutoCad 2000, is used as our CAD software, and is the core component in our design process. Information can be shared electronically with customers and vendors through dxf, dwg and iges file formats.
