Kolb Anlagenbau

What Kolb Anlagenbau does

Kolb Anlagenbau GmbH is a privately held German industrial boiler engineering company headquartered in Kerpen (Alfred-Nobel-Str. 15–19, 50169 Kerpen) that designs, builds, and services boiler systems for manufacturing, municipal, and utility customers. Its core offering spans steam boilers, hot water boilers, warm water boilers, and thermal oil systems, complemented by three proprietary branded products: the WDW (Wasser-Dampf-Wärmetauscher) water-steam heat exchanger, the MDT (Mikro-Dampfturbine) micro steam turbine for compact power generation, and the KKS (KolbKesselSteuerung) proprietary boiler control system for automated monitoring and management. The company operates four locations across Germany (Kerpen HQ, Dillenburg, Landsberg/Halle, Berlin) supported by two wholly-owned service subsidiaries — Kolb Industriekessel Service GmbH (Dillenburg) and Kolb Steamserv GmbH (Landsberg, Halle area) — and a service partner network (RAWEI Wartungsservice in Bremen, Flametech UG in Sassenburg) that together enable nationwide 24/7 emergency response.

The business model combines one-time project revenue from planning and installation with recurring maintenance, inspection, and TÜV/WHG compliance service contracts, plus usage-based mobile boiler rentals for temporary capacity. Kolb goes to market through direct enterprise field sales targeting industrial customers with complex boiler system needs; customer acquisition is built on technical expertise, regulatory certifications (WHG Fachbetrieb, Gas installer, TÜV), and long-term service relationships rather than price-based competition. Named customers include food processors (Pfeifer & Langen, Fortin Mühlenwerk, Fleischhof Rasting, Refresco Deutschland), energy and municipal utilities (MVV Enamic, Stadtwerke Kempen), and public-sector clients (Kölner Studierendenwerk, Hardy Remagen). The company positions itself as a full-lifecycle provider — planning, assembly, operations management, energy optimization (Eco), retrofit for alternative energy carriers ("Fit für die Zukunft"), and emergency support — and with 11–50 employees operates as a niche specialist in the German industrial-services segment where regulatory qualifications and field-service density are the primary competitive levers.
