What Munk does
MUNK GmbH is a family-owned German industrial manufacturer founded in 1970 in Hamm, Westphalia, specializing in DC power supply systems and rectifiers for electrochemical applications. The company designs and produces a portfolio spanning thyristor rectifiers (air- and water-cooled up to 100,000 A), switched-mode power supplies (the proprietary PSP family), pulse power supplies (AxD series), and custom special equipment, supported by in-house transformer manufacturing and the VPC 3.0 process control software. R&D intensity exceeds 10% of revenue, and production is fully concentrated at the Hamm headquarters with additional service operations in Sulzbach an der Murr and former sites in Oranienburg and Mittweida.
The business generates revenue through three streams: new equipment sales, used and rental equipment (with six-month warranty), and aftermarket services including maintenance, commissioning, modernization, and spare parts for both MUNK and third-party rectifier brands. Go-to-market combines direct enterprise sales in Germany with an international partner network spanning Europe, North America (USA/Canada via American Plating Power), Asia-Pacific (China, Singapore, India, Australia from 2026), the Middle East (Israel), and South America (Brazil).
The company serves horizontal end markets including automotive surface finishing and corrosion protection, industrial electroplating and anodizing, water treatment (drinking, process, ultrapure, wastewater, desalination), raw material extraction, and specialized electrochemical processes such as ECM and hydrogen electrolysis. Ownership remains concentrated within the Munk family, with Frank and Thorsten Munk as managing partners since 1997 and no external institutional investors.
