Kelso Technologies Executives to Discuss Joint Venture Opportunities in Latin America At Upcoming AAR Meeting


VANCOUVER, British Columbia, April 12, 2007 (PRIME NEWSWIRE) -- Kelso Technologies Inc. (TSX-V:KLS) (Other OTC:KEOSF), developer of the unique JS75 pressure relief valve, (the "Company") is pleased to announce that three top Kelso Executives will be attending meetings through the week of April 16th in Galveston, Texas in conjunction with the Association of American Railroads Tank Car Committee (AAR) Meeting which is held each April and October.

Kelso has identified a number of key priorities for the trip. Firstly, the Company is scheduled to meet to discuss opportunities to augment its sales efforts working in conjunction with a significant, railway products supplier serving (primarily) the Gulf Coast area of the U.S. where many chemical and petroleum shippers are located. Shippers are those most likely to purchase Kelso valves.

Secondly, following recent discussions and meetings held in Vancouver, Kelso will meet with a representative arriving from Mexico to further discussions regarding Latin American manufacture, licensing, and distribution of Kelso product.

Thirdly, Kelso will identify and discuss with potential candidates, their joining its newly-created Rail Advisory Board.

Finally, Kelso expects to meet with some existing customers as well as with potential new customers to further its sales of products within the United States.

According to Kelso President and CEO John Carswell, "The Tank Car Committee Meeting brings together a couple of hundred of the key decision makers in North America who will determine what valves are best suited for their cars. We have made inroads with several customers for both retrofitting tank cars with Kelso valves and for supplying new car builds and expect to see some positive sales opportunities evolve following these meetings. While sales to the rail industry take time, we are pleased that we also have so much interest in the manufacture and distribution of our technology in other parts of the world like Latin America and India to name a couple. International opportunities are key to our rapid growth and increasing return to our shareholders."

The Company also announces that it has granted 450,000 incentive stock options to consultants to the Company as follows: 200,000 options with an exercise price of $0.10; 150,000 options with an exercise price of $0.25 and 100,000 options with an exercise price of $0.45. These options are exercisable for a period of five years.
