25kw Trailer Mounted Generator – Doosan™

Doosan Portable Power’s G25 was designed with the customer in mind. Neatly laid-out gauges and diagnostic displays mean that users can quickly monitor the generator and diagnose problems. Simple operator controls ensure that training customers to use the G25 is easy. With a small footprint and variety of connections (GFCI, Twistlock, Terminal/Lug and optional Camlocks), the G25 can power everything a rental company could possibly serve: from powering concrete cutting tools to providing electricity at a festival.

The G25 is powered by a Mitsubishi engine that ensures longer run-time and maintenance intervals. The Leroy-Somer alternator keeps with Doosan Portable Power’s dedication to providing a reliable and efficient generator. Leroy-Somer alternators feature AREP – an extra set of windings that provide greater motor starting capability. This means that a larger motor can be started with a smaller generator that operates more efficiently than a traditional shunt generator. Additionally, Leroy-Somer’s alternators use Class-H insulation to protect it from moisture and dust.

The G25 from Doosan Portable Power is designed to be placed into any application and power your success!
