The Googol 400KW Open Frame Diesel Generator is powered by the Googol Power PTAA6L-EG490 engine (China Non-road Stage III), delivering a prime power of 400KW and a standby power of 440KW. Featuring a heavy-duty open-frame structure, this industrial-grade power solution is engineered for high performance and fuel efficiency, ideal for prime or emergency power supply in medium-to-large factories, data centers, infrastructure projects, and commercial complexes.
The core powertrain undergoes rigorous testing to ensure compliance with Stage III emission standards. With an ultra-low rated fuel consumption of just 1.00g/kw.h, it excels in energy saving and supports long-term continuous operation. The open-frame design enables superior heat dissipation, working in tandem with a fully enclosed water-cooling system to guarantee stable performance even in high-temperature environments. Daily maintenance is hassle-free with no need for disassembly, significantly reducing operational costs. Equipped with electric start, a Torchpower pure copper alternator, and an AVR automatic voltage regulator, the unit provides stable output with low harmonic distortion, safely powering heavy inductive and resistive loads for complex applications.
Widely used in manufacturing, mining, large-scale construction, hotels, hospitals, and municipal emergency services, this generator quickly responds to power outages or temporary capacity expansion needs. Leveraging Googol Power’s advanced common rail technology and the reliability of Torchpower alternators, the unit offers outstanding fuel economy, high stability, and a long service life, making it the preferred choice for high-end domestic generator sets in the 400KW class.
