Reliable Solutions
Power Solutions International understands the importance of reliable power. Our comprehensive line of power generation solutions is designed to meet the needs of OEMs and end users in the industrial, commercial, and utility sectors. From standard enclosures to custom-engineered solutions, our products are crafted with precision and built to endure even the harshest conditions, including seismic events, wind, and extreme climates.
Standard and Custom Enclosures
Our enclosures are more than just protective shells—they are integral to your power generation system. PSI’s UL FTSR- and FTTP-certified enclosures are designed to provide maximum protection and quality. They can house generators up to 5 MW and include custom-designed and manufactured UL 142 or UL 52804 fuel tanks, fuel conditioning systems, and switchgear. Each enclosure features a heavy-gauge, sloped TPO roof, ensuring long-lasting durability by eliminating standing water and leaks.
State-of-the-Art Manufacturing
PSI’s standard enclosures and custom power generation packages are designed, engineered, fabricated, and assembled in our facilities in Beloit and Darien, Wis., totaling more than 300,000 square feet. We also have electrical assembly and controls assembly capabilities at these locations.
Whether it’s a standard enclosure or a fully customized solution, every product is rigorously tested to ensure it meets the highest standards of performance and reliability.
Versatile Applications
Our enclosures are trusted by industries across North America. From utility power and mission-critical applications to offshore oil and gas platforms, commercial buildings, and specialized power systems, PSI enclosures are built to keep the lights on and the power flowing—no matter where you are. We provide power that keeps life-support systems operational during emergencies, ensures deep-sea oil rigs continue running, supports grid stability, and safeguards the world’s most vital information.
Custom-Engineered Solutions
At PSI, we go beyond traditional packaging to offer custom-engineered solutions tailored to your specific needs. We have full on-site capabilities to design and integrate a package to your specifications, including full modeling and simulation, custom software development, controls programming, durability and performance testing, customer-facing demonstration testing, and more.
Whether you’re powering a hospital, a remote industrial site, or placing a unit in a densely populated suburban area, our enclosures are designed to withstand the toughest environments on Earth. Our commitment to innovation is evident in every aspect of our enclosures—from advanced sound attenuation technology that reduces noise by up to 60 dBA to the full integration of emissions aftertreatment systems.
