ClearSign receives purchase order for two process heaters in California refinery

ClearSign Technologies announces the receipt of a purchase order to complete the detailed engineering of burners for two process heaters in a California refinery. This refinery was an early customer and has ongoing experience with the operation and performance of the ClearSign burner technology. This purchase order states that the procurement and fabrication of burners may be added at a later date, or not at all. If this order does continue to the supply of our equipment, it would displace an existing SCR system and help the refinery adhere to the stricter emissions regulations in California.
