Kelso Technologies Inc.: AAR Approves New JS165H High-Flow Pressure Relief Valve

VANCOUVER, BRITISH COLUMBIA and DOWNERS GROVE, ILLINOIS--(Dec 4, 2014) - Kelso Technologies Inc. ("the Company" or "Kelso") (KLS.TO)(NYSE MKT:KIQ) reports that the Association of American Railroads (AAR) has approved our new JS165H high-flow pressure relief valve (PRV) for commercial applications after completing its required two year field trial.

The JS165H has been designed for use on general service rail tank cars carrying hazardous and non-hazardous non-flammable chemicals that require a pressure specification of 165PSI. Rail tank cars requiring this technology are primarily DOT-111 tank cars that represent approximately two-thirds of the total DOT-111 fleet in North America.

North American chemical companies have been very supportive of the development of the JS165H as a best available technology and we are now able to supply their needs. Management believes that this development will allow Kelso to increase its market share and continue the momentum of its annual revenue growth.

With this AAR approval Kelso is now able to supply approximately 70% of all PRV applications required by the AAR. The JS165H is well suited for new tank car manufacturers, retrofit operations and repair facilities. The Company is able to produce this product in its current production facilities in Bonham, Texas.
