Question by: Wayne W on Sep 14, 2025, 9:49 PM
Got a mobile hydraulic system running up to 85 GPM on a piece of equipment that puts out a fair amount of heat. Would this cooler actually keep up with that kind of load?
Answer by: Customer Support on Sep 16, 2025, 9:14 AM
At 85 GPM you'd have plenty of headroom here. The unit handles oil flows up to 100 GPM and is rated to pull out up to 90,000 BTU/Hr, so it's built for systems that run hard. The 1-1/4 NPT ports support that flow without restriction, and the copper tube and aluminum fin core is designed to move heat efficiently. For a mobile application pushing that kind of volume, this size fits the job well.
Question by: Frank B on Oct 29, 2025, 2:04 PM
running about 85 gpm through it, am i gonna choke the flow with these 1-1/4 ports?
Answer by: Customer Support on Oct 30, 2025, 3:05 PM
With 1-1/4 NPT ports, this exchanger is built to support oil flow rates up to 100 GPM, so 85 GPM is within its stated flow capability.
