Liquid-Cooled 11kW Diesel Standby Generator for Backup Power
Kubota Lowboy II Series GL11000 11,000-Watt Diesel Standby Generator
Product Overview
The Kubota GL11000 is a heavy-duty diesel generator designed to provide dependable electrical power for commercial, industrial, construction, and standby applications. It delivers 11,000 watts (11 kW) of standby power and 10,000 watts (10 kW) of prime power, making it suitable for demanding loads where reliable power is essential.
The generator uses Kubota's compact Lowboy II configuration, which combines a vertical liquid-cooled diesel engine with direct coupling to create a low-profile package. This design helps conserve installation space while maintaining the durability expected from a commercial-grade generator.
Note: Kubota's current official documentation identifies the GL11000 as a Lowboy II model. Some retailers market it under the name “Lowboy Pro II,” so the model designation should be verified when ordering.
