Fenton Art Glass has signed a 15-year contract for AGA Gas Inc., Cleveland, OH, to supply oxygen for its melting furnaces. AGA will erect a remote-controlled on-site oxygen generating system at Fenton's manufacturing plant in Williamstown, WV, where nine glass melting furnaces are in operation. The new on-site supply system will use pressure-vacuum swing adsorption (PVSA) technology to produce 26 tons of oxygen a day. It will replace a liquid oxygen and vaporizer system and is expected to reduce oxygen costs by 50 percent.
