5 Ways to Leak Test Refrigeration Condenser Coils

All types of refrigeration appliances and systems contain condenser coils. Though they may vary in size and design, they share the common need for leak testing in manufacturing. Their shape and the number of brazed joints to be checked can make detecting leaks a challenge, and the use of more ... Read More

How to specify a helium reclaim system for your plant

As manufacturers face yet another helium shortage and increasing costs for the rationed supply, many are looking at reclaim systems to optimize their helium usage. These systems can, depending upon the application, recover up to 95% of helium for reuse. Read More

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? ...

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
