Tecogen
(60 and 75 kW Recip)

Tecogen, Inc. is a leading manufacturer of gas engine-driven equipment. The company markets three product lines: TECOCHILL engine-driven chillers in the 50-1000 ton size range; TecoFROST engine-driven refrigeration compressors up to 440 HP; and 75 kW TECOGEN cogeneration modules. Tecogen has an in-house sales staff that manage an independent sales representative network based throughout the United States and the world. Tecogen also has a marketing group, and an extensive service network with service employees in several major cities across the United States.

Tecogen was formed in the early 1960's as the R&D/New Business Center of Thermo Electron Corporation. For the next 20 years, this group performed fundamental and applied research in many energy-related fields to develop new technologies.

In 1982, the group released its first major product, a 60 kW cogenerator, and followed this five years later with a 150 ton engine-driven chiller. In 1987, Tecogen, Inc. was spun out by Thermo Electron as a separate entity. In 1992, Tecogen became a division of the newly formed Thermo Power Corporation along with two other Thermo Electron subsidiaries, Crusader Engines and FES. Thermo Power acquired NuTemp in 1994, to complete the four divisions of Thermo Power.

In 2000, Thermo Power Corporation was dissolved and Tecogen was sold to a group of four investors that included the original founder of Thermo Electron, Dr. George Hatsopoulos; the former president of Thermo Electron, John Hatsopoulos; Craig Drill Capital, a private investment firm based in New York City; and Fox River Financial Resources, a private investment firm based in Batavia, Illinois.

Tecogen presently services over 250 cogeneration units ranging in size from 30 kW to 650 kW. Over 73 cogeneration sites are serviced through our New York/New Jersey service center.

TecoDrive 7400 ... the proven prime mover

The TecoDrive 7400 is a proven eight-cylinder, 454 cubic inch displacement, naturally aspirated, four-stroke, spark-ignited engine, specially developed by Tecogen and the gas industry for efficient natural gas operation. Since first introduced in 1984, more than 1,100 natural gas engine-powered cogeneration, chiller, and refrigeration units have amassed more than 15 million hours of dependable service at approximately 650 customer sites across the U.S. and abroad. Individual TecoDrive engines normally operate for about 20,000 hours between overhauls … the equivalent of one million miles, or 40 times around the earth in vehicle service. The exceptional engine life is due to the inherently clean combustion of natural gas fuel, the de-rating of output to 1800 rpm for cogeneration, as well as a number of customized durability enhancements, including positive valve rotators, improved coolant distribution, and increased oil flow to bearings, camshaft, and cylinder walls.
