What is an integrity test for heat exchangers?
An integrity test is a diagnostic method designed to verify the mechanical and hygienic reliability of your gasketed plate and tubular heat exchangers. It detects leaks and identifies early signs of corrosion or fatigue before they develop into costly failures. Understanding what an integrity test is helps you plan maintenance, avoid contamination, and secure consistent product quality. This heat exchanger leak detection method provides the insight needed to maintain control over your process and safeguard uptime. In addition, the proactive approach gives you confidence in the reliability of your equipment.
How does the heat exchanger leak test procedure work?
The heat exchanger leak test procedure uses a non-toxic, non-flammable mix of hydrogen and nitrogen is pumped through your heat exchanger(gasketed/tubular), revealing any microscopic cracks, corrosion or material fatigue. Our precision sensors pick up any discharge of gas and identify the type of flaw - micro-cracks, corrosion, gasket failure, and more.
Each integrity test section takes about 15 minutes, giving accurate, real-time data on the condition of your plates and gaskets. The results let maintenance teams act fast, prevent cross-contamination, and extend equipment lifespan through data-driven upkeep.. Watch this explanatory animation.
