Assemblin strengthens ventilation and building management systems (BMS) capabilities by acquiring Ehlin & Larsson AB (“Ehlin & Larsson”), with offices in Västerås, 24 employees and annual sales of approximately SEK 40 million.

Ehlin & Larsson is a well-established installation company founded in 1999 by brothers Anders and Tore Ehlin, who are still active in the company. Today, the business focuses primarily on air-treatment installations with a growing share of building management systems integration and energy projects. The company offering includes package solutions for smart energy optimisation developed in-house, showing energy-saving measures to property owners based on automated collection and follow-up of input data. The largest customers include construction companies such as HMB, PEAB and Byggmäster, as well as property companies such as Mimer and Hemsö.

“We are very pleased to be able to acquire Ehlin & Larsson, an innovative ventilation and BMS company with high level of technical expertise. Their project and customer portfolio complements our operations in the Mälaren Valley very well providing us the scope to offer their innovative BMS solutions to our customers as well,” says Håkan Ekvall, Managing Director and Business Area Manager for Assemblin Ventilation.

Of Ehlin & Larsson’s 24 employees, 14 work with service, energy efficiency and BMS. The company also has the capacity to carry out design work with its own designers.

“Development has progressed very rapidly and the demand for BMS solutions relating to technical installations is increasing fast. Assemblin has distinguished itself as a good and stable owner, focusing on technical expertise and digitalisation. We see a clear advantage in a shared future where we can develop both our employees and customer offerings together,” say Anders and Tore Ehlin at Ehlin & Larsson.
