Frequently Asked Questions

The 30kW liquid-cooled Protector Series provides 2,000 more watts than the 28kW air-cooled, but more importantly, it’s built to commercial standards with liquid cooling for extended continuous runtime. While the 28kW air-cooled is the most powerful air-cooled unit available, the 30kW liquid-cooled is designed for applications requiring weeks of continuous operation or commercial-grade reliability. The liquid-cooled design handles heat dissipation better, extends engine life, and supports higher duty cycles. It weighs 807 lbs vs 524 lbs and costs significantly more.
Yes. We pull all required electrical and gas permits for Houston, Harris County, and surrounding jurisdictions. We coordinate all inspections and ensure your installation passes code requirements. This is included in your installation price.
Liquid-cooled generators require maintenance every 2 years or 400 hours of operation. Given the investment in a 30kW unit and its typical commercial-grade usage, we strongly recommend annual professional maintenance including oil changes, coolant system service, radiator inspection, fuel system checks, and battery maintenance. The extended intervals between major services (400 vs 200 hours) offset some of the additional cooling system complexity. We offer comprehensive maintenance plans specifically designed for liquid-cooled units.
