The Thermo-TR shell-and-tube heat exchanger recovers heat from energy-consuming processes at temperatures up to 1600¯F (871¯C). Energy can be recovered and returned as process make-up air, used to preheat combustion air, or used for plant or office heating. Heat transfer tubes are fully welded to the tube sheets, ensuring minimum cross-contamination. Integrated expansion joints make the heater suitable for high-temperature applications. Single and multi-pass models are available with effectiveness up to 80%.
