Streamlined Manufacturing and Installation Achieves Revolutionary Performance

SEATTLE – February 7, 2017 – ClearSign Combustion Corporation (NASDAQ: CLIR), an emerging provider of industrial combustion technologies that help to reduce emissions and improve efficiency, today announced that it has launched a new burner product based on its Duplex™ technology for refinery and industrial process heater applications. The market opportunity is global with an existing installed base numbering in the tens of thousands – all candidates for the outstanding performance offered by the Duplex Plug & Play product.

The innovative Duplex Plug & Play design provides a simple, pre-engineered and standardized direct burner replacement for traditional refinery heaters with the proven features of ClearSign’s unique Duplex technology. Unlike existing burner solutions, the evolution  of the Duplex technology into an off-the-shelf product reduces the customized engineering associated with typical retrofits while delivering unparalleled low emissions and the elimination of flame impingement. Globally, flame impingment has been a challenge that virtually all refineries and industrial combustion users face, costing many hundreds of millions of dollars annually in lost production, unsafe conditions, and maintence costs.

The product derives its name from the fact that the installation does not require a heater or furnace to be shut down. Rather, the heater can continue to operate while the Duplex Plug & Play is installed through the burner mounting point, connected to the utilities, and turned on. The ability to install the Duplex Plug & Play while the system is operational allows customers to avoid costly down time and immediately start enjoying the benefits of the product while shortening the sales cycle often prolonged by scheduled maintence, often months or years in the planning.

“This product is a game changer,” said Stephen Pirnat, Chairman and CEO of ClearSign. “Our Duplex research and development team, working with customers, have set a new industry standard by capturing the features that refineries desire, literally all over the world. We are excited to deliver and install the first units within the next 60 days to a customer in Texas for field testing. Pending favorable field results, we anticipate interest from a number of OEMs for licensing and potential manufacturing arrangements.”

Prior to introduction, the Duplex Plug & Play was subjected to months of rigorious laboratory testing that mimicked refinery operating conditions expected to be experienced during the field test. Field testing at the refinery in Texas will provide the last phase of product validation and allows for operational feedback from our beta site customer. The customer has expressed interest in purchasing a number of systems once the testing is completed.
