Day Tanks

Although the double-wall tank is now our standard offering, we continue to provide single-wall systems with or without rupture basins. Critical Fuel Systems also offers a full range of day tank trim accessories, including level controls and fill manifolds, to meet the specific requirements of each project.

Filtration

Diesel fuel has a limited shelf life when left untreated and begins to degrade shortly after refinement. Residual water from the refining process, combined with water vapor entering through atmospheric tank vents, can condense on tank walls and accumulate at the bottom of the storage tank.​

To support fuel readiness in mission-critical and critical care facilities, Critical Fuel Systems Fuel Maintenance and Filtration Modules remove water and condition the fuel, ensuring diesel is clean, stable, and ready when needed.

Pump Sets

Critical Fuel Systems manufactures complete diesel fuel pump sets for mission-critical applications. Our standard duplex pump sets range from 36 GPH to 3,000 GPH, and custom configurations can be engineered to meet a wide variety of fuel oil system requirements. Built with positive displacement pumps, our systems are designed for safe, reliable operation and engineered with environmental protection in mind.

controls

As fuel systems grow in scale and regulations become more stringent, control systems for mission-critical applications must become increasingly sophisticated. Critical Fuel Systems has developed a modular control platform designed to meet these evolving demands.
Our approach focuses on standardized systems with configurable features that can be activated on-site, along with a range of optional enhancements that can be added as needed. These expandable systems are designed to support on-site growth and accommodate even the most ambitious expansion plans.
