SEATTLE, Dec. 11, 2014 /PRNewswire/ -- ClearSign Combustion Corporation (NASDAQ: CLIR) ("ClearSign"), an emerging leader in combustion and emissions control technology for industrial, commercial and utility markets, announced today that its Board of Directors has appointed Board member Stephen E. Pirnat as ClearSign's Chairman and Chief Executive Officer, replacing Richard F. Rutkowski, who resigned his officer and director positions with ClearSign on December 10, 2014. Until Mr. Pirnat assumes office, James N. Harmon, ClearSign's Chief Financial Officer, will act as interim President (principal executive officer).

Mr. Pirnat, who joined the ClearSign Board of Directors in November of 2011, has extensive experience in the energy supply and services sector, including as the former President and CEO of the John Zink Company, LLC, a subsidiary of Koch Industries and a global leader in the supply of combustion and environmental equipment to the refining, petrochemical, production/exploration and utility industries.

"Steve is a transformational leader with a proven track record of building shareholder value through the development and successful commercialization of innovative products and a focus on operational excellence," said ClearSign Director, Scott Isaacson. "The board believes he is ideally suited to lead this next phase of ClearSign's development as ClearSign continues its transition from a development phase into a product and customer focus. Steve's experience makes him the ideal candidate to lead ClearSign forward."

At John Zink, Mr. Pirnat oversaw a period of rapid growth both in revenue and profitability, driven by several new product innovations and multiple synergistic acquisitions.

"I am honored to have been asked by the Board to lead ClearSign into the next phase of its growth," said Pirnat. "The opportunities for ClearSign's game-changing technologies are immense, and I am very excited to be a part of it."

Commenting on the transition, Scott Isaacson added, "On behalf of ClearSign and the Board, I want to express our heartfelt gratitude to Rick for his vision. From little more than a revolutionary idea when ClearSign was founded in 2008, through a period of rapid development of both technology and intellectual property, Rick's efforts have enabled ClearSign to build a foundation upon which to grow."

Mr. Pirnat was most recently Managing Director of Europe, the Middle East and African operations at Quest Integrity Group, a division of Team Industrial Services, a provider of asset integrity management and asset reliability solutions in the refinery, chemical, petrochemical, pipeline and power industries worldwide. From 2009 to 2011, he was President of Quest Integrated Inc., a technology incubator and boutique private equity firm. From 2000 to 2009, Mr. Pirnat served as President & CEO of the John Zink Company, LLC, a wholly owned subsidiary of Koch Industries and a worldwide leader in the supply of combustion and air pollution control equipment to the energy industry. Mr. Pirnat, a long-time executive with Ingersoll-Rand and Ingersoll-Dresser Corporation, went to John Zink from a previous post as President & CEO of Pangborn Corporation, a leading supplier of surface preparation equipment and associated services to the automotive and aircraft industries. Mr. Pirnat began his career as an applications engineer with the Pump and Condenser Group of Ingersoll-Rand, where he advanced through a variety of sales, marketing, engineering, and operational positions with that company and its successor, Ingersoll-Dresser. These positions included Vice President of Ingersoll-Rand's Standard Products Division, Vice President of Marketing for Ingersoll-Dresser Pumps, President of Ingersoll-Dresser Pumps Canada Ltd., and Vice President & General Manager of Ingersoll-Rand Engineered Equipment Division. Mr. Pirnat received a BSc. in Mechanical Engineering from the New Jersey Institute of Technology.
