Kelso Technologies Inc.: New Patent-Dual Rating Pressure Relief Valve

VANCOUVER, BRITISH COLUMBIA and DOWNERS GROVE, ILLINOIS -- (Marketwired) -- 02/20/14 -- Kelso Technologies Inc. (TSX VENTURE: KLS)(OTCQX: KEOSF) - The Company reports that it has filed a patent application for a new externally mounted dual rating pressure relief valve ("DPRV") design for use on new rail tank cars and retrofits of existing rail tank cars.

Recent derailments of trains carrying hazardous materials have raised US and Canadian government concerns over railroad safety. Regulatory bodies are focused on finalizing design criteria for safety enhancements to existing railroad tank cars carrying flammable liquids including crude oil and ethanol. These concerns center on the quality and effectiveness of service equipment including pressure relief valves used for containment of hazmat during rail operations in both non-accident and accident events.

Kelso has initiated a proactive design strategy based on these regulatory concerns and as a result we have created a new DPRV design that based on mechanical engineering innovations that provide safety benefits in both accident and non-accident environments. In general terms in an accident involving fire the DPRV will significantly lower its operating pressure rating to a level that will keep the valve open in order to evacuate the tank car in less than 100 minutes as required by AAR recommendations. This is a dramatic change to current technology capability. In addition, Kelso believes the DPRV will provide economic advantages to the impact of the expense of retrofits facing the railroad industry.

The patent has been filed under a "Non-Publication Request" which keeps the patent filing private until the patent is issued. We have done this for competitive reasons as keeping our invention out of the eyes of our competition until we launch the commercial product carries various market advantages for Kelso. Our competition will most likely become aware of our DPRV when we submit our Application for Approval to the AAR, however they will not have enough details on the design to allow them to try to circumvent our ideas. The final patent will likely take 2 years or more to be granted and carry a 17 year life starting from the date the patent is granted.

The DPRV will enter Association of American Railroads (AAR) approval process shortly after the prototypes are completed in May 2014. The Company will announce AAR approvals by press release when they are received.
