ESSI subsidiaries Fermont, Pivotal Power, Radian, and UPSI provide rugged, reliable, transportable electrical power generation and conditioning systems safeguarding critical applications worldwide.

  • Deployable power generation and distribution systems
  • Military generator sets
  • Uninterruptible power supplies (UPS)

Fermont has focused its resources on supplying military generator sets, auxiliary power units (APU) and other power equipment to the United States Armed Forces and other government agencies. As a result, Fermont has become the leading designer and largest supplier of Tactical Quiet Generator Sets to the US military.

An example of Fermont's leading design and engineering capability is the 3KW Tactical Quiet Generator (TQG) Set. Emphasis was placed on reducing weight and noise for the safety of the soldier without sacrificing reliability and performance. This is the first generator set produced for the U.S. Army with a Permanent Magnet Generator (PMG) and variable speed technologies. Several thousand 3KW TQGs have been manufactured by Fermont under the Army's first production contracts for these products.3kW Tactical Quiet Generator

Radian was awarded the 10-year Deployable Power Generation & Distribution System (DPGDS) contract by the U.S. Air Force (USAF) in March of 1998. The purpose of DPGDS is to provide US military with an airlift deployable and/or over the road, highly reliable, and logistically affordable electrical power system of minimum size, weight, and fuel usage, thus reducing the size of aircraft and number of sorties necessary to deploy and sustain operations. This system affords U.S. military field commanders unparalleled flexibility in meeting a wide array of operational contingencies.
