How does our Integrity Test for heat exchangers work?

Our Integrity Test offers unmatched accuracy and safety. 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. The heat exchanger test takes as little as 15 minutes per section. With this test our experts detect cracks in your unit’s plates and evaluate the risk of media cross-contamination. Watch this explanatory animation.
