TLD ACE was founded in 1953, under the name of Accessory Controls & Equipment Corporation, to manufacture unique test equipment for the aviation industry. With the introduction of jet airliners in the mid 1950’s, the ACE product line expanded to include airline ground support equipment (stored air or Bottle Jet Starters) and support equipment for use by utility companies at gas turbine power generating plants. In the late 1950’s, ACE helped usher in the space age with custom designed environmental control systems for launch pad use.

Further evolution and development of the product line throughout the 1960’s resulted in corporate growth and added military applications to the existing environmental control products.

Boom years and an increasingly global demand in the 70s resulted in expansion on all product lines. ACE advances in environmental control systems placed the company years ahead of any competitor.

Market leading technical progress continued throughout the company history. In 1980 TLD ACE introduced the first screw compressors for the ground support industry. In 1983, the first ACE continuous flow jet starter with an AERZEN compressor was designed and produced. In the early 1980’s TLD ACE was instrumental in developing the world’s largest screw compressors with female rotor drive. In 1989, TLD ACE purchased the assets of NORDCO to further expand the product range of ACE.

TLD ACE introduced the first ground support environmental control system to use R-134a, an ozone safe refrigerant in 1990, the same year it introduced its GPU line. ACE was acquired by the TLD Group in 1991. Subsequently TLD ACE’s primary focus became the development of its commercial product lines and sales with the support of the TLD network.
