Sell Shell-and-Tube Heat Exchangers From Water and Wastewater Facilities

Shell-and-Tube Heat Exchangers in Water and Wastewater

A shell-and-tube heat exchanger is a robust thermal transfer device consisting of a bundle of tubes enclosed within a cylindrical shell. One fluid flows through the tubes while a second fluid flows over the tubes within the shell, facilitating heat transfer between the two. In a water or wastewater facility, the documented process context matters: In the water and wastewater industry, heat exchangers are primarily utilized for energy recovery and maintaining optimal temperatures in processes such as anaerobic digestion and sludge treatment. These facilities often employ various types of heat exchangers, including spiral, tube-in-shell, and plate designs, to transfer heat from treated wastewater or biogas systems to incoming processes.

This page combines the approved shell-and-tube heat exchangers identification record with the approved water and wastewater process record. It does not infer condition, suitability, ownership, or value from an industry label alone.

Identification and documentation checklist

A seller should connect the physical unit to its service and records before requesting evaluation. For this intersection, document both the asset construction and its actual water and wastewater duty.

• Verify ASME code stamp and TEMA designation (e.g., TEMA C, R) on the nameplate.
• Check for maximum allowable working pressure (MAWP) and temperature ratings.
• Inspect tube bundle type (fixed, U-tube, or floating head) and material (e.g., carbon steel, stainless steel, copper alloys).
• Review maintenance logs for tube plugging, fouling factors, or chemical cleaning history.
• Maintenance logs showing chemical descaling history.
• Records of struvite and vivianite removal.

Condition and value factors

Suitable for high-pressure and high-temperature applications. That technical characteristic is only one input; current condition, completeness, documentation, demand fit, installed scope, and logistics also influence review.

Heat exchangers from wastewater treatment facilities may show heavy scaling and fouling. Service history and residual-process disclosure should therefore be evaluated with the equipment record rather than treated as an automatic positive or negative value conclusion.

• Current photographs and readable nameplate
• Dimensions, weight, quantity, and installation state
• Known metallurgy and service fluid
• Inspection, cleaning, repair, and operating history
• Seller authority and intended disposition timing

Commercial review boundary

Submission requests a fact-based buying review. It does not guarantee purchase, price, payment timing, removal, loading, freight, or reuse. Those terms require separate written confirmation after the equipment and project facts are reviewed.
