Bubbles or Beeps? – Using Leak Detectors to Pinpoint Gas Leaks

Whether you’re working with residential HVAC systems or large commercial refrigeration setups, the ability to detect leaks efficiently and safely can save time, money, and prevent potential hazards. One of the most effective ways to find a leak in a HVAC or refrigeration system is to use an electronic leak detector to find the general area of the leak and then use a solution such as Big Blu to pinpoint the exact location.

Leak Detection with the OG Bubbles

It’s the OG (original) leak detector for a reason, Refrigeration Technologies’ Big Blu has been a staple in the HVACR industry for over 25 years.

So, what makes it so special?

Superior Visibility: Big Blu is capable of detecting gas leakage down to 0.65 ounces per year. By creating a vivid, long-lasting bubble that clings to the surface, even in challenging conditions, it’s easier to spot even the smallest leaks.

Versatility: Use on any gas, including oxygen. Big Blu is non-corrosive and safe to use on all types of metals, including aluminum, brass, and copper. This versatility makes it ideal for use in a variety of systems, including HVAC, refrigeration, and plumbing.

Safety: Big Blu is a water-based, non-toxic solution, making it environmentally friendly and safe for technicians to handle. It’s also biodegradable and NSF registered for use around food. It does not contain chlorine, aliphatic amines, or ammonium compounds.

Find the Leak Fast

When combined with an electronic leak detector, Big Blu enhances the overall leak detection process, ensuring that even the smallest leaks are found and addressed. Here’s a step-by-step guide on how to use these tools together:

1. Initial Sweep with an Electronic Leak Detector:
   
   • Start by using an electronic leak detector, such as Fieldpiece, to perform an initial scan of the system. This tool is excellent for quickly identifying general areas where leaks may be present. Move the detector slowly over joints, connections, and other potential leak points.
     
2. Pinpointing with Big Blu:
   
   • Once the electronic detector has identified potential leak areas, apply Big Blu directly to those spots. The solution will form bubbles at the site of any leak, allowing you to pinpoint the exact location. The combination of the electronic detector’s sensitivity and Big Blu’s visual confirmation ensures no leak goes undetected.
     
3. Confirm and Repair:
   
   • After identifying the leak, make the necessary repairs. Reapply Big Blu to ensure that the leak has been fully sealed and the repair is effective.

Big Blu’s Backstory and How It’s Made:

Big Blu was created as there was a need for a reliable, non-toxic leak detection solution. Before Big Blu, many technicians relied on soapy water mixtures or less effective products, which often failed to detect smaller leaks or caused corrosion over time. Big Blu revolutionized the leak detection process by providing a product that not only delivered superior results but also cared for the techs using it and the systems it was used on.

The product quickly gained popularity and today, Big Blu is the go-to solution for anyone needing reliable leak detection. Big Blu is still manufactured directly in Anaheim, CA, each batch is carefully balanced and mixed perfectly to ensure the mixture has the right balance of viscosity and surface tension for long-lasting bubbles.

Available Options:

Big Blu is available in its original spray formula, a brush-on version that comes with a 10-inch extension dauber, as well as Subzero, which is freeze-resistant and has a temperature rating down to -30°F.
