Kelso Technologies Inc.: Commercial Dual Rated Pressure Relief Valve

VANCOUVER, BRITISH COLUMBIA and DOWNERS GROVE, ILLINOIS--(Marketwired - April 24, 2014) - Kelso Technologies Inc. (TSX VENTURE:KLS)(OTCQX:KEOSF) - The Company reports that it has successfully developed its dual rated pressure relief valve ("DPRV") for commercial applications. The new DPRV has been designed pursuant to an industry-wide request by the Association of American Railroads ("AAR") and the Rail Supply Institute ("RSI") for higher performance standards for pressure relief valves used on rail tank cars carrying crude oil, ethanol and other flammable commodities. This is a key part of ongoing regulatory efforts by the United States and Canada to provide safer DOT 111 tank cars.

On February 20, 2014 Kelso announced that it had filed a patent application for its DPRV design for use on new rail tank cars and retrofits of existing rail tank cars. Our design team successfully created the DPRV based on our existing patents that cover our external constant force spring pressure relief valve ("EPRV") design. Our DPRV features simple mechanical engineering innovations to our existing EPRV platform. The new DPRV is designed to exceed the AAR and RSI recommended safety benefits in both accident and non-accident environments.

In general terms in a rail tank car accident involving fire our DPRV will significantly lower its operating pressure rating based on temperature only to a level that will keep the valve open in order to evacuate the tank car in less than 100 minutes as specified by AAR recommendations. This is a dramatic change to current technology capability. In addition, Kelso believes its DPRV will provide economic advantages to the impact of the expense of retrofits facing the railroad industry. Our DPRV is an extension of our current EPRV products so that it fits seamlessly to existing tank car designs and can be retrofitted in the field to minimize costs.

Our unique approach to the DPRV will allow Kelso, in a very short time frame after final AAR approval, to deliver a proven high performance product at production capacities that exceed all North American railroad annual OEM, retrofit and repair needs for this product. Our new 44,000 square foot facility in Bonham, Texas in combination with our existing 47,000 square foot facilities have been designed to produce the DPRV in desired volumes commencing in July 2014.
