Building automation secures a 300-million deal
More than 300 million euros of debt capital is being channelled into the acquisition of a majority stake in MDT technologies. This financing demonstrates the strong confidence investors have in building services technology when products integrate directly with heating, ventilation, lighting control and digital building automation.
The loan supports BU Bregal Unternehmerkapital’s entry into MDT technologies, which is acquiring a majority stake from IK Partners. Partners Group provided the funding on 15 September 2026 through its direct lending strategy and classifies MDT as a European platform for building automation.
For the property sector, this is more than just a financing deal. Based in Engelskirchen, MDT develops and manufactures KNX-based components for the automation of residential and commercial buildings. The product range extends from sensors and actuators to solutions for lighting, climate control, shading and remote access. The transaction therefore falls squarely within the technology sector that is driving refurbishments, operational optimisation and smart retrofitting in existing properties.
Growth through the building’s ‘engine room’
MDT was founded in 1984 and, according to its own statements, has been manufacturing in Germany for 40 years. Partners Group notes that the company has more than doubled its production over the past five years and expanded its portfolio to around 600 products. MDT describes itself as one of the leading manufacturers of KNX products for residential and commercial building automation.
The fact that a financing package of over 300 million euros is being mobilised for this purpose underlines the growing importance of building-related technology in the private equity market. The focus is not on visionary platform promises, but on hardware, sensor technology and control systems that are installed directly in buildings and have a measurable impact on energy consumption, comfort and operations there.
New owner, familiar pressure to expand
MDT had already announced the entry of BU Bregal Unternehmerkapital back in July 2026 and spoke of a continued growth trajectory. At the time, the company highlighted the expansion of its international activities, several acquisitions and an expanded production and administrative site in Engelskirchen. This is relevant for owners, developers and operators of large portfolios because it is suppliers such as these that determine how quickly building automation can be rolled out on a large scale.
For Partners Group, the financing is also part of a significantly more active year for lending. Following the MDT transaction, the European Direct Lending Strategy 2026 has so far made 23 investments with a total deployment of nearly 2 billion euros. This shows that debt-financed takeovers are once again being carried out with considerable impact, even in niche sectors of building services engineering.
