“… we sent out 2 turbine lube oil coolers to National Heat Exchange. They turned around both coolers in a 10 day outage with little issue… We made a trip to their facility and they are very capable for cleaning and fabricating coolers… They use the same process in the shop as they do on-site.”


“… the hydrogen cooler cleaning National Heat Exchange performed for us earlier this spring has been a great success…. prior to the cleaning we ran with the cooling water control valve wide open and still could not get the gas temperatures as low as we would like. After cleaning, the cooling water control valve is running in the 20%-30% open range and the gas temperature is right at the level we desire. Thank you and your company very much for your support on this project. And please pass along our thanks to the crew that performed the cleaning here on-site. Their work has provided a great improvement on the cooling capability of the Unit #3 hydrogen coolers. And the crew was a pleasure to work with. their professionalism, experience and patience through our set-up delays was greatly appreciated.”

“The cleaning of our lube oil coolers was a complete success. Prior to the outage we were running with a lube oil temp of 130ºF (115ºF desired) with both coolers in service, the water control valves wide open and the cooling water at 55ºF. After the cleaning we are running with the desired 115ºF lube oil temp with one cooler in service, the water control valve 23% open and the cooling water at 64ºF. Thank you very much to you and your team for helping us get our coolers back to cooling the way they should. And please pass along our thanks to the team that was here for this work. They were very professional and great to work with. They are welcome back at our site any time.”
