Vestas aircoil A/S is a manufacturer of charge air coolers, intercoolers and cooling towers founded in the small Danish town of Lem in Jutland.

DieselHouse is an interactive exhibition on diesel technology located on the grounds of the still operating H. C. Ørsted Power Station in the South Docklands of Copenhagen, Denmark.  The exhibition is centred on a gigantic decommissioned Burmeister & Wain diesel engine which was the world's largest for more than 30 years. Burmeister & Wain was a large established Danish shipyard and leading diesel engine producer headquartered in Copenhagen, Denmark.  Founded by two Danes and an Englishman, its earliest roots stretch back to 1846.  Over its 150-year history, it grew successfully into a strong company through the end of the 1960s.  In the 1970s, global competitive pressures, particularly from the far east, began to take their toll.  In 1980, B&W became MAN B&W Diesel A/S, part of MAN B&W Diesel Group, a subsidiary of the German corporation MAN AG, with operations worldwide.  The company still maintains operations at three main sites in Denmark for manufacturing, servicing, and licensing of its two-stroke engines and complete propulsion systems. The MAN B&W K108ME-C is a low speed two-stroke turbocharged diesel engine for marine engineering applications.  It is designed by the Danish department of the German diesel engine supplier: MAN Diesel SE, the former MAN B&W Diesel group, and part of the larger MAN SE. Refshaleøen, originally an island in its own right but now annexed to the larger island of Amager, is a former industrial site in the harbor of Copenhagen, Denmark.

Early Paxman diesel engines (with "Comet" indirect injection cylinder heads, designed by Sir Harry Ricardo) carried the name Paxman Ricardo. MAN Diesel & Turbo SE is a multinational company based in Augsburg, Germany that produces large-bore diesel engines and turbomachinery for marine and stationary applications, as marine propulsion systems, power plant applications and turbochargers.
