Corporate Company Profile
The Trane Company (U.S.) began as a family business more than a century ago. Its roots were set in 1887 when James Trane opened a plumbing shop in La Crosse, Wisconsin, U.S. In 1913, he and his son, Reuben, incorporated The Trane Company to produce a new type of low-pressure steam heating called "Trane Vapor Heating". Reuben patented the convector radiator, the successor to the cast iron radiator, in 1926. The convector proved to be the product which launched The Trane Company into worldwide prominence.More innovative products followed, such as the unit
heater and the fan-coil.

In 1931, The Trane Company produced its first air conditioner. Seven years later it established a reputation as an innovator by developing a revolutionary refrigeration machine that cooled more efficiently at a lower operating cost than others on the market. By continually improving its products over the years, Trane has become one of world's largest manufacturers of air conditioners and continues to set industry standards.

In 1984, Trane was acquired by American Standard, Inc. which includes: American Standard, Ideal Standard plumbing, heating and air conditioning division; WABCO commercial and utility vehicle braking and control systems division, Trane heating and air conditioning products, LARA and Copalis medical diagnostic system division.

Today, Trane is a multi-billion dollar company and is recognized worldwide for its technology and quality products.
