Strategies for HVAC Leak Testing

Every heating, ventilation, and air conditioning (HVAC) system should be free from leaks to be efficient and safe. However, leaks can be introduced into HVAC systems during manufacturing and assembly, and aging HVAC systems can develop leaks over time. Because many refrigerant leaks are small, they ... Read More

How to achieve accurate low leak rate testing: Adapting to new manufacturing standards in the refrigeration and air conditioning industry

Leak testing of pipe joints, tubes and fittings in refrigeration and air conditioning components such as coils and compressors during assembly manufacturing is critical. Tests must be accurate and reliable, or products could have serious problems for consumers in the field.  Recent changes to the ... Read More

Reliable, automated alternatives to dunk tank leak testing

Dunk testing remains a common leak test method due to its simplicity and relative affordability. This traditional approach, however, can be highly subjective and prone to error, leading manufacturers to look for ways to achieve a more objective and reliable leak test—but what’s the best method? ...

Helium 101, Part 2: Different methods of trace gas leak testing

In the previous post, we discussed helium and other alternative the options available for trace gas leak testing. Helium’s relatively low ambient presence in atmosphere, its inert nature and its very small atomic dimensions make it ideally suited for use as a trace gas.  These characteristics, as ... Read More

Helium 101, Part 1: Choosing a Trace Gas

When trying to determine the optimal test method for any application one can be faced with a bewildering array of methods and solutions, each with its own caveats.  Usually the first decision to make is whether traditional leak testing methods using air as a test medium are suitable for the ...

Forming gas is an effective and safe trace gas alternative to helium

For trace gas leak testing, helium has ruled for years. It’s inert, has a very low presence in ambient air and its atomic size makes it ideal for detecting the smallest leaks. This makes it a common choice for products in which the acceptable leak rate approaches zero – airbags, refrigeration ... Read More

Ensuring Accuracy with Helium Leak Testing: The Noise in the Background

Helium leak testing: from airbags to air-conditioning units and fuel rails, from anything implanted in the body to hermetically sealed enclosures for integrated circuits, there are some instances where the acceptable leak rate is so small it’s practically zero. Since air leak test methods such as ... Read More
