About a decade ago, a pivotal request from PG&E led to a breakthrough in gas pressure regulator testing. ESC developed both manual and automated Regulator Testing Machines (ARTM), setting new standards for accuracy and safety in the industry. Our expertise includes pressure regulating testing, pressure regulator testing, and testing commercial regulators for natural gas applications. Following the success with PG&E, Southern California Gas also implemented our ARTM technology in their meter shops. By 2021, ESC’s innovations reached numerous gas utilities across the U.S. and Canada. Features like Internal Relief and Over Pressure Shut Off ensure regulators are thoroughly tested and reliable, safeguarding customers at every level.
