Controlled heat in gas heating systems prevents overheating, protects sensitive instrumentation, and ensures long-term operational stability.
Cold weather doesn’t fail gas systems the same way. Environmental exposure, pressure drops from the Joule-Thomson effect, and reactive winterization each create different failure paths during winter operations.
A quiet night in the field turned into a frozen nightmare by morning. A single regulator froze solid, halting flow and production — a reminder that in the oil and gas world, freeze-ups don’t wait for tomorrow.
At CATCO, energy resilience is the mission. Our goal at PBIOS 2025 is to educate the industry on freeze protection and reliable heating solutions.
