History

From GEA to Digood

It has been a long journey from starting as GEA back in 1920 to becoming Digood in 2015.

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32.

There are many variations of passages of Lorem Ipsum available, but the majority have suffered alteration in some form, by injected humour, or randomised words which don't look even slightly believable.

The generated Lorem Ipsum is therefore always free from repetition, injected humour, or non-characteristic words etc.

Milestones

1920: Foundation of GEA in Bochum by Otto Happel Sr. (Born 1882)

Founded on 2 February 1920, GEA, abbreviated from the original German name of the company “Gesellschaft für Entstaubungs-Anlagen mbH”, was the work of a man who was an entrepreneur with heart and soul, a man gifted with an exceptional technical insight and filled with the desire for pioneering technical innovations.

1922: Happel’s closed-circuit cooling system with elliptical finned tubes

For Otto Happel, his first objective was clear: to introduce “closed-circuit cooling” in Germany and to develop it as quickly as possible for use in large installations. Just two years after setting up his small business he had achieved that objective, and Happel’s closed-circuit cooling system differed from those of his European and overseas competitors in only one – but one very important – aspect. Instead of the conventional heat exchanger (round tube exchangers with wrapped finning or pressed-on rectangular fins) Happel installed the “elliptical finned tube”, his first independent technical development which to this day is a key product in the GEA heat exchanger range.

1925: Renaming to GEA Luftkühlergesellschaft mbH

On 15 February 1925, Happel renamed his company “GEA Luftkühlergesellschaft mbH”, Bochum. With its soundly engineered products, it quickly developed a good reputation. Just two years later, on the basis of the elliptical finned tubes GEA developed air coolers for transformers, air-to-water coolers for rectifiers, forced air coolers for compressors, coolers for diesel locomotives and steam-powered rail cars.

1935: The Air Cooled Condenser – a Technical Milestone

For Otto Happel, his first objective was clear: to introduce “closed-circuit cooling” in Germany and to develop it as quickly as possible for use in large installations. Just two years after setting up his small business he had achieved that objective, and Happel’s closed-circuit cooling system differed from those of his European and overseas competitors in only one – but one very important – aspect. Instead of the conventional heat exchanger (round tube exchangers with wrapped finning or pressed-on rectangular fins) Happel installed the “elliptical finned tube”, his first independent technical development which to this day is a key product in the GEA heat exchanger range.

1948: Otto Happel Sr. passed away

Founded on 2 February 1920, GEA, abbreviated from the original German name of the company “Gesellschaft für Entstaubungs-Anlagen mbH”, was the work of a man who was an entrepreneur with heart and soul, a man gifted with an exceptional technical insight and filled with the desire for pioneering technical innovations.

1953: Beginning of a New Division

For Otto Happel, his first objective was clear: to introduce “closed-circuit cooling” in Germany and to develop it as quickly as possible for use in large installations.
