Kelso Joins Railroad Supply Institute

VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 7, 2011) - James R. Bond, CEO and President of the Company (TSX VENTURE:KLS) is pleased to announce that Kelso's application for membership in the Railway Supply Institute ("RSI") has been accepted.

Mr. Neil Gambow, CEO and President of the Company's wholly owned subsidiary Kelso Technologies (USA) Inc. comments that, "RSI is one of the oldest trade groups in the rail industry. 'The mission of RSI is to support, connect and advocate for railway suppliers. RSI connects members to their customers and partners, supports the improvement of the industry, assists members in the global marketplace, and represents the industry during the regulatory and legislative process.'"

Kelso will be displaying its valves and new patented manway securement system at the RSI trade show held in Minneapolis, MN on September 18-21, 2011. This trade show is held every four years and is the premier rail trade show in North America. Kelso intends to be active on RSI committees that will be beneficial to the Company's growth and reputation as a reliable supplier of high quality "best of technology" products.

About Kelso Technologies

Kelso designs, engineers, markets, produces and distributes innovative proprietary products including constant force pressure relief valves and a new unique manway securement system that are designed to reduce the risk of environmental harm due to non-accidental events in the transportation of hazardous commodities via railroad tank cars in North America. Operations are based in Vancouver, British Columbia, Chicago, Illinois and Bonham, Texas.

The Company's innovative "best of technology" products and production facilities now meet the demanding design, testing and production standards of the Association of American Railroads ("AAR"). Kelso is now focused on the full scale commercial marketing and distribution of its proprietary technologies in 2011.

With the economic recovery in North America, the enforcement of US and Canadian environmental regulations for shippers of chemical commodities and the adverse effects of wear and tear on existing railroad fleets, management expects that the railroad industry will rebound significantly. Management is confident that its reorganization in 2010 has laid the foundation from which to pursue a market made up of over 700 new tank-car builders, major chemical shippers, repair shops and retrofitters. This will allow the Company to grow its new MSS and pressure relief valve business successfully over the coming years. The Company will update, by way of news releases, progress reports in the future.

For a more complete business and financial profile of the Company, management encourages interested parties to view the Company's website at www.kelsotech.com and public documents posted on www.sedar.com.
