In 1959, Elektriska maskinfirman P.O. Hermansson AB was founded. The company worked with installation and service of heating systems and was active until the summer of 1985 when P.O. Hermansson retired.

The former employees Ove Andersson, Curt Kullberg, Karl-Erik Jansson, Ingvar Jansson then took over the company and formed AKJ Energiteknik AB. Today AKJ is owned and operated by Gustav Jansson, Martin Jansson and Ingvar Jansson.

The largest customers include heating plants throughout the Nordic region, but also various industries and major property owners.

AKJ currently services a few hundred plants, many of which the company has serviced since the sixties. The broad experience of servicing existing heating plants has given AKJ unique knowledge of the combustion of all kinds of fuels, ranging from various bio-oils to landfill gas and residual products from wood industries and food production.

Every year we rebuild several heating plants that are adapted to customers' new needs and fuel availability. New control systems are installed, grate systems and incinerators are adapted to optimize combustion, etc.
