POWERTHRU, a subsidiary of Phillips Service Industries, Inc. (PSI), designs and manufactures advanced flywheel energy storage systems. The company was launched in November 2010 after PSI acquired the assets of Pentadyne Corporation's flywheel manufacturing business in July 2010. PSI, founded by William T. Phillips in 1967, is a global manufacturing and services holding company with a portfolio of technology-driven businesses serving industries such as aerospace, defense, and energy.
POWERTHRU's core business revolves around providing a high-reliability, low-maintenance, and environmentally sound alternative to traditional lead-acid batteries for Uninterruptible Power Supply (UPS) systems. The company's products are designed for commercial and government applications, providing ride-through power and voltage stabilization for power quality and recycling applications. Their systems are particularly suited for harsh environments and are used in data centers, hospitals, and industrial settings to protect sensitive equipment. The business model focuses on manufacturing and selling these advanced kinetic energy storage units, which can either supplement or entirely replace conventional battery banks.
The company's flywheel technology stores energy kinetically in a spinning mass, which rotates at high speeds in a vacuum to minimize drag. A key feature is the use of a carbon-fiber-composite flywheel cylinder and a magnetically levitated, bearing-free design, which eliminates a common mechanical failure point and reduces maintenance costs associated with traditional systems that require bearing replacements. Their patented molecular vacuum sleeve and a synchronous reluctance motor-generator contribute to higher energy efficiency compared to competitors, with significantly lower standby energy consumption and heat generation. This technology offers a long lifespan of over 20 years, rapid recharge capabilities, and a smaller physical footprint compared to battery systems with equivalent output.
