BM Green Cooling

What BM Green Cooling does

BM Green Cooling GmbH is a German specialty engineering firm headquartered in Schwarzenbruck near Nürnberg that designs and delivers turnkey industrial cooling systems for paper mills, data centers, and process-industry facilities across Europe. Founded in 2009 under current owner and Managing Director Eberhard Knödler, the company operates as an owner-managed private limited company (GmbH) with approximately 25 employees and ISO 14001 certification. Its solutions target mission-critical cooling applications requiring continuous 24/7 operation, with documented energy cost reductions of up to 90% versus conventional mechanical cooling, PUE values as low as 1.09 for data center installations, and an average customer ROI of approximately 1.5 years.

The product portfolio combines multiple cooling technologies—freecooling, natural cooling, absorption cooling, adiabatic cooling, mechanical cooling, and heat recovery—on a unified Siemens S7 control platform. Core product lines include the proprietary Paper Line climate cabinets with coated pipes, large coil surfaces, and corrosion-resistant designs tailored to sulfide-laden paper mill air; a special low-temperature absorber operable with 70°C hot water (approximately 20°C below market alternatives) that converts waste heat to chilled water; the compact L-Units for ceiling installation in space-constrained E-rooms; and an IT cooling range (SideCooler, FrontCooler, High Density Reardoor Cooler up to 40 kW per unit). Notable installations include a 3,600 kW E-room cooling system at Palm Aalen PM5, a 2,400 kW freecooling system at Hamburger Rieger Spremberg PM2, and what is described as the world's first data center cooled 100% with geothermal water.

Revenue is generated through project-based turnkey engagements—feasibility study, planning, plant engineering, commissioning, and long-term 24/7 service—combined with hardware sales of chillers, drycoolers, absorbers, heat exchangers, and air handling units. Go-to-market is direct enterprise sales with experienced project managers serving as primary customer contacts, supported by free non-binding initial assessments, a website with industry-segmented lead capture, a virtual showroom web application, and detailed project case studies. The customer base spans major paper producers (Palm, Schoellershammer, Hamburger Rieger, Drewsen, Niederauer Mühle) and data center operators (Fujitsu, Bisping & Bisping, LEOLUX) across Germany, Sweden, the Netherlands, and Mauritius.

Products and services

• SideCooler A cooling system installed at the side of IT racks in data centers, featuring a high-efficiency heat exchanger that removes heat from the air and provides cool air for the racks. Space-saving and cost-efficient solution for data center operators.
• FrontCooler Cooling system designed to be installed at the front of IT racks, featuring a high-efficiency heat exchanger. Available in water-cooled and DX variants. Eliminates need for separate air duct system for data center applications.
• High Density Reardoor Cooler Cooling system specifically designed for tight spaces where racks need to be placed in limited areas. Offers up to 40 kW cooling capacity per unit for high-density data center deployments.
• Paper Line Climate Cabinets Climate cabinets purposefully engineered for the paper industry, featuring coated pipes and coils, Siemens S7 as standard control units, and extremely large coil surface areas to optimize fluid temperatures. Enables freecooling up to 80% of the year.
• L-Units for Ceiling Installation Space-saving ceiling-installed climate cabinets offering all benefits of Paper Line climate cabinets but requiring less footprint in E-rooms, specifically designed for paper machine environments with limited space.
• Drycooler Equipment for indirect freecooling that transfers cold via pipe system to water-glycol mixture. Features upward-opening fans for cleaning and special coatings against aggressive outside air.
• Chiller Classic cooling method available in air-cooled and water-cooled variants. Features modern Turbocor compressors and Siemens S7 controls. Water-cooled versions can be placed inside or outside buildings.
• Absorber (Absorption Chiller) Uses hot wastewater for cooling, replacing electrical energy with heat energy. No refrigerants with GWP required. Special low-temperature absorber operates with 70-degree hot water, approximately 20 degrees colder than previous market solutions.
• Adiabatic Cooler Cooling equipment that uses water evaporation as cooling method. Vaporizing sprayed water creates a cooling effect that can be utilized in the cooling system for energy-efficient operation.
• Air Handling Units State-of-the-art German-made air handling units for outdoor placement when building space is limited. Only ducts run inside the building for air distribution.
• Heat Exchangers Water-water heat exchangers specifically designed for demanding cooling conditions. Feature particularly powerful, optimized designs often implemented in redundant configurations.
• Turnkey Cooling Solutions Full-service project delivery from first ideas through planning, construction, commissioning, and long-term service and maintenance. End-to-end cooling solution delivery for enterprise customers.
• Consulting and Feasibility Studies Feasibility studies, economic calculations, heat load calculations, weather studies, groundwater studies, and refrigerant guidance services for cooling projects.
