Detnet / About Us / History



In 1990 Expert Explosives (ExEx) and Altech Technologies in the shape of Detotech independently began to develop electronically programmable detonators for the mining industry. By 1995 both companies had shown working products to the market. In 1993 AEL acquired a controlling interest in ExEx. Around the same time Imperial Chemical Industries (ICI) took a controlling interest in AEL. In 1998 ICI divested its explosives business which became ORICA whilst AEL reverted to 100% AECI. The technology in ExEx in the form of Smartdet was passed to ICI worldwide except for African market where AEL was licensed to use ExEx products. In 1999 AEL purchased Detotech and its Electrodet product. The two businesses were amalgamated formed into DetNet. In order to address a worldwide market a 50% share of DetNet was, in 2004, sold to Dyno Nobel ASA. The joint venture remains in place to this day servicing the worldwide market for programmable electronic detonators.
