The public company Kelso Technologies Inc. began as a mining equipment supplier in March 1987. Over time the focus of the company moved into the railroad supply industry. By 1996 Kelso's new VP of Engineering, Barry LaCroix, had developed a pressure relief valve for the North American rail tank car market for which Kelso would act as the distributor. The company was a small player and they never really gained sales traction with the pressure relief valve that received regulatory approval and became available for sale in 2001.
After the US economy shrank in late 2008 and throughout 2009, Kelso struggled financially. At this time a business developer by the name of James R. Bond was asked by the Board of Directors to review the company's financial status to see if he could help to turn it around. He recognized the potential of the company and in April 2010 he and other key management began the rebuilding process. With a newly patented manway technology to offer in addition to the pressure relief valves, the company began the regulatory approval process for the manway and commenced the marketing of their ‘safer technology for the transport of hazardous goods’ to the rail tank car industry.
