This article is about the heating, ventilation, and air conditioning system manufacturer. For the holding company, see Trane Technologies. For the saxophonist nicknamed "Trane", see John Coltrane.
In 1913, James and Reuben, along with Stella Jackson (formerly Trane), incorporated The Trane Company. By 1916, the Trane's were no longer in the plumbing business, but instead focused their attention on manufacturing heating products. Reuben's invention of the convector radiator in 1923, which replaced the heavy, bulky, cast-iron radiators that prevailed at the time, was a major success. Trane's first air conditioning unit was developed in 1931.
In 1982, Trane purchased General Electric's Central Air Conditioning Division.[2][3] With that purchase came many of the most recognizable traits of Trane's residential air conditioning products. Many of those traits, like the distinctive red "Climatuff" compressors, rotary compressors, the "Spine-Fin" all aluminum spiny outdoor coil and the all aluminum evaporator coil, are still found in Trane's residential equipment lines.[4]
On February 1, 2007, American Standard Companies announced it would break up its three divisions. The company sold off its namesake kitchen and bath division and spun off WABCO, American Standard's vehicle controls division, while retaining Trane. American Standard then renamed itself Trane Inc. effective November 28, 2007.[5][6]
On December 17, 2007, Trane announced it had agreed to be acquired by Ireland-based Ingersoll Rand in a cash and stock transaction.[7][8][9][10] The sale was completed on June 5, 2008.[11][12]
In 2020, Ingersoll Rand spun off its non-refrigeration businesses and was rebranded as Trane Technologies.[15]

Map of the Channel Tunnel
The Channel Tunnel is a 50.45-kilometre (31.35 mi) rail tunnel beneath the English Channel, linking the United Kingdom with France. At its lowest point, it is 75 m (250 ft) below the sea bed and 115 m (380 ft) below sea level.[16][17][18] At 37.9 kilometres (23.5 mi), the tunnel has the longest undersea portion of any tunnel in the world.[19] During the design stage of the tunnel, engineers found that its aerodynamic properties and the heat generated by high-speed trains as they passed through it would raise the temperature inside the tunnel to 50 °C (122 °F).[20] As well as making the trains "unbearably warm" for passengers this also presented a risk of equipment failure and track distortion.[20] To cool the tunnel to 30 °C (86 °F), engineers installed 480 kilometres (300 mi) of 0.61 m (24 in) diameter cooling pipes carrying 84 million liters (18.5 million gallons) of water. The network—Europe's largest cooling system—was supplied by eight York Titan chillers running on R22, a Hydrochlorofluorocarbon (HCFC) refrigerant gas.[20][21]
Due to R22's ozone depletion potential (ODP) and high global warming potential (GWP), its use is being phased out in developed countries, and since 1 January 2015 it has been illegal in Europe to use HCFCs to service air-conditioning equipment—broken equipment that used HCFCs must instead be replaced with equipment that does not use it. In 2016, Trane was selected to provide replacement chillers for the tunnel's cooling network.[20] The York chillers were decommissioned and four "next generation" Trane Series E CenTraVac large-capacity (2600 kW to 14,000 kW) chillers were installed—two located in Sangatte, France, and two at Shakespeare Cliff, UK. The energy-efficient chillers, using Honeywell's non-flammable, ultra-low GWP R1233zd(E) refrigerant, maintain temperatures at 25 °C (77 °F), and in their first year of operation generated savings of 4.8 GWh—approximately 33%, equating to €500,000 ($585,000)—for tunnel operator Getlink.[19][21]
