Question by: Phil B on Apr 9, 2025, 5:36 PM

Hey, I'm looking at this heat exchanger for a hydraulic system on a piece of mobile equipment. How hot can the oil get before I start running into trouble?

Maximum operating temperature is 350°F. You'll want to keep it below that to ensure optimal performance and prevent damage.
