Omnitek Engineering, San Marcos, Calif., is moving into a new facility that's double the size of its current location, in anticipation of strong domestic demand for diesel-to-natural gas engine conversions, as well as continued international market growth.

The Environmental Protection Agency recently approved the company's submission for its diesel-to-natural gas conversion technology for the Navistar DT466E and DT530E engines under criteria related to the agency's Outside Useful Life definition.

"In addition to conversion activities related to these two Navistar engines and the different configurations, which represents an estimated addressable market of 1.5 million potential conversions, the new facility is designed to support additional engine development programs -- including sales support, training and manufacturing," said Werner Funk, president and chief executive officer of Omnitek Engineering.

"We are continuing to focus on appointing dealers and authorized installers to support anticipated demand for conversions, and look forward to significant domestic growth from the build-out of our domestic conversion centers across the United States," Funk added.

The company expects to obtain EPA approval for other diesel engine models. Omnitek's patented technology, which has been used outside the United States since 2001.

The company's new headquarters will be located at 1333 Keystone Way, Vista, California, effective March 1, 2013.
