The ESI Story
Through our relentless focus on standby power reliability, we have committed ourselves to being the innovative leaders and responsible industry experts in proven, engineered life cycle management of diesel fuel supply and filtration systems for standby power generators. Because we are a manufacturer, we are the only company that guarantees the reliable operation of equipment during emergencies, while deploying the engineering capability to service competitor equipment as well.

Manufacturing
Ninety percent of diesel generator shutdowns are due to fuel-related failures. We are a manufacturer who continues to create reliable infrastructures for data centers that depend on diesel engine standby power. Our patented “ESI Clean Fuel Systems” boast unprecedented N+3 reliability and are engineered to maintain reliability in the tank and deliver quality fuel to the engines for reliable starting where and when it's needed. We are the first and only industry experts to guarantee supply, quality, equipment servicing and reliability testing in one package. We are the only company who can boldly claim to have a complete system for eliminating diesel generator failure through comprehensive diesel fuel management, starting with selection of fuel at the tank farm and ending with reliable, clean quality fuel both in the tank and in the engine. If you don't believe us, ask the data centers we protect. Not one of our data center customers has experienced a fuel related failure.
