Company History

Algas-SDI - historic photoIn 1932 American Liquid Gas Corporation (later known as Algas Industries) received its first patent for a unique vaporizer – the direct gas fired vaporizer for use with LP-Gas. This type of vaporizer soon became the standard throughout the Americas and many other places around the world. Later, in 1937, the design was improved and another patent was issued on the pre-cursor to what is now called the 40/40H and 80/40H. Algas Industries also manufactured a popular line of engine carburetors that was later sold to IMPCO.

The E. Sam Dick Company, formed in 1958 by E. Sam Dick and Verle Brown, quickly became known for its Natural Gas replacement systems utilizing LP-Gas. As the company grew and designed new products, they recognized the need for a vaporizer that could lend itself to very compact installations with little or no ongoing maintenance. Electric vaporizers at the time all used water as the heat transfer medium and customers had to constantly fight corrosion and re-fill the water. Thus the birth of the dry electric vaporizer – several national and international patents were awarded to Sam Dick Industries beginning in 1972.

In 1994 Algas Industries acquired the assets of Interex Gas Systems based in Washington State and relocated to Dallas, Texas. Later, in 1999, Algas-Industries and Sam Dick Industries joined forces forming Algas-SDI International, LLC.

Algas-SDI now has the widest product offering in the industry – a benefit to you.
