Glen Dimplex

What Glen Dimplex does

Glen Dimplex Deutschland GmbH is a wholly-owned subsidiary of the family-owned Glen Dimplex Group (Dublin, Ireland), operating from Kulmbach in Upper Franconia, Germany, where it manufactures electric heat pumps up to 180 kW and precision cooling units up to 226 kW at a plant with roughly 1,000 employees. The entity runs two product brands: Dimplex, which delivers heating, heat pumps, domestic hot water, and ventilation for residential and commercial buildings, and Riedel Kooling, which supplies high-precision process cooling for laser machines, MRI systems, 3D printers, plastics and food production, and other industrial OEMs. All products are fully electric-powered and use natural refrigerants with a global warming potential of 3, positioning the portfolio for building decarbonization and F-Gas regulatory tailwinds; third-party Fraunhofer ISE research quantifies a 64% CO2 reduction versus natural gas systems.

The company's go-to-market combines regional enterprise field sales across Germany (North, South-West, South-East), key-account managers targeting planners and consultants, an internal sales/order-processing team, an OEM channel embedding cooling into third-party industrial equipment, and a dedicated field-service network for installation and maintenance of both Dimplex and Riedel Kooling installations. Revenue is generated primarily through hardware sales of standardized and custom-configured HVAC and cooling systems, supplemented by recurring service and maintenance contracts; pricing is quote-based and not publicly disclosed. Within the broader Glen Dimplex Group — which reports approximately EUR 2 billion in annual turnover across four divisions (Heating & Ventilation, Customer Appliances, Flame, and Precision Cooling) and operates additional manufacturing in Kalamazoo (USA) and Shenyang (China) — the German entity functions as the center of competence for heating, ventilation, and precision cooling engineering, with quality systems certified to ISO 9001:2015 and supply-chain processes compliant with the German Supply Chain Due Diligence Act (LkSG).
