Heat Exchanger Integrity Testing

Why should I do integrity testing?

Integrity Testing is a preventative field test used to identify microscopic cracks and material fatigue before they develop into harmful leaks. Ideal for plate heat exchangers and shell and tube models.

Convenient

• Unit does not need to be fully-drained, some remaining water will not affect test results
• No need to open plate packs
• Can be used on hard-to-access units

Quick

• Precision sensors pick up any discharge of gas in as little as 15 minutes per section
• No cleaning or other post-test procedures needed

Accurate

• The 5-10% hydrogen-nitrogen mix reveals flaws smaller than liquid can permeate
• The mixture has a lower probability of false positives than other tracer gases
• Automated detection system minimizes possibility of user error
• Can identify type of flaw: micro-crack, corrosion, gasket failure, etc. anywhere within your unit

Safe

• The 5-10% hydrogen-nitrogen mix is non-toxic, non-flammable, and approved for food industry use
• Does not stress or corrode plates or gaskets

Sustainable

• No helium needed (helium is a scarce, non-renewable energy source)
• Uses hydrogen and nitrogen which are sustainable, non-scarce resources which can be used without environmental harm
