Established in 1904, Cummins Generator Technologies manufactures alternators under the renowned STAMFORD® and AvK® brands setting the industry standard, with a range extending from 7.5 to 11,200kVA, suitable for all generator set configurations.

Although our products are used in a variety of applications, the common factor is that Cummins Generator Technologies work to a single standard for both products and services no matter where you are in the world. With six manufacturing plants, based in Europe, Asia and India, we work to one global standard, so each of our plants build products to the same exacting quality that has come to distinguish our alternators in the industry.

All of our plants utilise the same sophisticated manufacturing technologies, advanced systems, common practices and rigorous testing techniques to ensure STAMFORD® and AvK® alternators are built to last.

Cummins Generator Technologies is part of Cummins Inc. a global power leader and Fortune 500 corporation that designs, manufactures and distributes engines and related technologies, including fuel systems, controls, air handling, filtration, emission solutions and electrical power generation systems.
