Used Heat Exchanger Buying Considerations
When selecting a used heat exchanger, it is important to evaluate both process requirements and equipment condition:
Condition & Maintenance History: Review refractory lining, heating elements, and prior use
Heat Transfer Requirements: Evaluate temperature differences and thermal duty
Fluid Compatibility: Ensure materials match corrosiveness and cleanliness requirements
Pressure & Temperature Ratings: Confirm suitability for operating conditions
Design Type: Shell & tube, plate, or air-cooled based on application
Fouling & Maintenance Needs: Consider ease of cleaning and maintenance
Condition & Service History: Review wear, scaling, and prior usage
