Used Denyo DCA-220SPK2 220kVA (220KW) Silent Diesel Generator – Pre-Owned & Load Tested

Used Denyo DCA-220SPK2 220kVA (220KW) Silent Diesel Generator – Pre-Owned, Serviced, Heavy-Duty Ready

This listing is for a used Denyo DCA-220SPK2 silent diesel generator, a high-capacity unit from Japan’s premier generator manufacturer. The DCA-220SPK2 is part of Denyo’s renowned DCA series, engineered for demanding industrial applications requiring substantial power output combined with quiet operation . This generator has been thoroughly inspected, professionally serviced, and load tested to ensure reliable performance, offering exceptional value compared to new equipment.

Why Choose a Pre-Owned Denyo Generator?
Denyo generators are built to last, with robust construction and premium components designed for service lives that can reach 20 years and beyond . This used unit delivers the same Japanese engineering excellence at a significantly reduced price—ideal for contractors, mining companies, industrial facilities, and event producers looking to acquire high-capacity reliable power on a budget.

Heavy-Duty Sound-Attenuated Canopy
Like all Denyo DCA-Series generators, this model features a fully enclosed, soundproof canopy constructed from solid-steel with weatherproof design . The canopy utilizes highly effective sound insulating materials to minimize operational noise . Suitable for noise-sensitive environments including urban construction sites, residential areas, hospitals, and overnight events, the weather-resistant enclosure also protects internal components from dust, rain, and harsh site conditions.

Power Output & Engine
The DCA-220SPK2 delivers 220 kVA (220 KW) of robust power at 60Hz (or approximately 183 kVA at 50Hz), with 3-phase, 4-wire output. It is powered by a heavy-duty industrial diesel engine from a leading Japanese manufacturer, featuring direct injection for fuel-efficient operation and stable performance under varying loads. Denyo generators utilize highly reliable diesel engines with low fuel consumption, manufactured by Japan’s leading engine manufacturers .
