In the early years of the 21st century, small, durable, reliable industrial and marine engines continued to be a staple, notably the ALPHA water-cooled industrial and marine engines (2-, 3- or 4-cylinder) and the "T" air-cooled series (1-, 2- or 3-cylinder). Engines and diesel generating sets continued to be assembled and sold from a factory on the original Dursley site, with the product range expanded to include more powerful engines and a wider range of generating set specifications. In 2007 a new heavy-duty engine, the OMEGA, offering up to 268 kW, was added to the company's product range.
