In 1906 Dalén became chief engineer at the Gas
Accumulator Company (manufacturer and distributor of acetylene) and in 1909 when AGA was founded, he was appointed the managing director for the company. During his life, AGA was one of the most innovative companies in Sweden and produced a large variety
