Assemblin strengthens its position in Örebro through the acquisition of heating and sanitation company Essén Rör AB

Assemblin VS has acquired Essén Rör AB, a well-run and well-established heating and sanitation company with annual sales of approximately SEK 70 million and 45 employees.


Essén Rör was founded in 1978 and is currently the largest heating and sanitation company in the Örebro region. The operations are split evenly between contract operations and service operations. Its customers consist primarily of construction companies, large and small property management companies, insurance companies and industrial companies as well as municipalities and county councils. About one third of its service assignments consist of framework agreements with major customers.

“We have been holding discussions with representatives of Essén Rör for some time and are very pleased to now be able to finalise this acquisition. Essén Rör is a well-managed and profitable company with a sound culture and a focus on quality, which fits well with Assemblin’s profile. Together, we will be in a strong position for continued expansion in the Närke region,” says Andreas Aristiadis, President and Business Area Manager for Assemblin VS.

Essén Rör is an authorised HVAC company; all of its employees are “Säker Vatten” certified and several also have other specialised licenses.

“We are proud of the operations we have developed, and of the tremendous skills we possess today. Assemblin has a strong reputation in the market and is an excellent owner that can enable us to continue developing our operations. Assemblin’s strengths in several technical areas, which we can offer to our customers, is something we also view positively. This is a natural step for us that will benefit our employees and our customers,” says Mikael Essén, President and principal owner of Essén Rör AB.
