A generator keeps your business running during prolonged power failures by delivering sustained, dependable electricity across your site. Unlike an uninterruptible power supply (UPS) system, which provides instant short-term protection, generators deliver long-duration backup power for hours or even days, ensuring continuous operation when the mains supply is down.
At Shenton Group, our diesel generator systems are engineered for performance, resilience and long-term reliability. They integrate seamlessly with UPS and automatic transfer switch (ATS) systems to form a complete critical backup power solution.
Whether you’re protecting a hospital, data centre or manufacturing facility, our generator solutions are built to keep your critical operations powered, compliant and productive — whatever happens.
A UPS ensures your business remains operational during power interruptions by delivering instant backup electricity to critical systems. Unlike generators, UPS systems prevent downtime and protect sensitive equipment from damage caused by even momentary power loss.
At Shenton Group, our UPS systems provide seamless power continuity, bridging the gap between mains failure and generator start-up while safeguarding your infrastructure from costly disruption.
Whether you’re protecting a data centre, hospital, or industrial facility, our UPS solutions are engineered for reliability and certainty.
A UPS system provides:
UPS systems are essential in environments where even milliseconds of power loss can cause data corruption, equipment failure, or operational disruption.
