Viessmann Group acquires service unit of Weiss Kesselbau

Munich, 01 December 2015. Insolvency administrator Dr. Jan Markus Plathner of the law firm BRINKMANN & PARTNER sold the service unit of Weiss Kessel-, Anlagen- und Maschinenbau GmbH to Viessmann Group.

2015_11_Weiss_Viessmann_RECOVWeiss Kessel-, Anlagen- und Maschinenbau GmbH, located in Dillenburg, has been producing boiler plants for biomass power stations for over 80 years and offers designated know-how in development and design of customized boiler plants. Particular focus of Weiss are boilers ranging from 20 to 50 megawatts thermal power and more than 2,000 customized Weiss boilers are in use worldwide. In 2014 Weiss realized revenues of EUR 19 million with its 56 employees; production has been outsourced several years ago. Because of difficult market conditions for biomass power stations over the last years, Weiss had to file for insolvency on July 6th 2015. The district court of Wetzlar ordered preliminary insolvency administration and appointed attorney-at-law Dr. Jan Markus Plathner from law firm Brinkmann and Partner, Frankfurt Main, as preliminary insolvency administrator.

The insolvency administrator succeeded in stabilizing business operations as well as continuing major projects and thereby set the foundation for an international sales process. In the scope of the sales process OMNICAL Industrieservice GmbH – a 100% subsidiary of Viessmann Group, a worldwide leading manufacturer of heating and cooling systems with over 11,500 employees and more then EUR 2.2 billion revenues – acquired Weiss service unit including employees through an asset deal.

ACXIT Recovery Management acted as exclusive M&A advisor to insolvency administrator Dr. Jan Markus Plathner.
