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, Chicago and Bonham, Texas.

The Company's innovative "best available technology" products and production facilities now meet the demanding design, testing and production standards of the 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.
