It consisted of a new style of heat exchanger in a sheet metal cabinet—a highly efficient, lightweight replacement for the bulky, slow-responding castiron radiator. In 1931, The Trane Company developed its first air conditioning unit, the Trane unit cooler, and in 1938 its first centrifugal refrigeration machine, the Turbovac. [7]
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.
The heating radiator was invented by Franz San Galli in 1855, a Kingdom of Prussia-born Russian businessman living in St. Petersburg. [2] [3] In the late 1800s, companies, such as the American Radiator Company, promoted cast iron radiators over previous fabricated steel designs in order to lower costs and expand the market.
The Detroit Radiator Company was founded in 1882 by Henry C. and Charles C. Hodges. [1] The Pierce Steam Heating Company was founded in 1881 by John B. Pierce and Joseph Bond in Buffalo. [3] The Standard Radiator Company (Buffalo) was established in 1892 by Nelson Holland. [4]
San Galli received a radiator patent in 1857, [2] while American Joseph Nason developed a primitive radiator in 1841 [3] and received a number of U.S. patents for hot water and steam heating. Nason's patent for tapered pipe threads in particular is cited by 1930s writer Ara Marcus Daniels as the key development in the birth of the radiator. [3]
