Commercial and industrial professionals rely on heat exchangers to transfer heat energy and remove unwanted heat in diverse applications. The service lives of heat exchangers generally range from 10 to 20 years, providing the exchangers are well-maintained. However, constant contact with high temperatures and pressures takes a toll on heat exchangers, which often causes premature failure. Should equipment failure occur, you have an important decision to make: to repair the faulty component or to replace it. Your decision will depend on your budget and the specific issues at hand.

Serviceable and Non-Serviceable Issues

Many issues can be rectified without replacing a heat exchanger. Fouling (or contamination) inhibits proper heat transfer, but this issue can be repaired quickly (with a high maintenance cost though). Heat exchanger tube bundles are also easily replaceable components. Flow misdistribution is another serviceable issue, usually caused by poor design or installation and if just looking to replace the tube bundle go to

On the other hand, cracking found in heat exchangers are not serviceable. The leading cause of this issue is system overheating—insufficient airflow leads to heat stress, which in turn leads to cracks near the weakest areas in the metal material. Cracked heat exchangers must be replaced immediately to protect other system components and to prevent carbon monoxide leakage.
