Trace-A-Gas (TAG)


Trace-A-Gas is a premium leak detection solution to help you find a refrigerant leak. Trace-A-Gas is a 5% Hydrogen and 95% Nitrogen mixture which is non-flammable, non-toxic and safe for the environment. When used with a suitable electronic leak detector, Trace-A-Gas will enable engineers to detect much smaller refrigeration leaks than they can with Oxygen Free Nitrogen and a leak detection spray.

Product Features & Benefits

  • Hydrogen is the smallest molecule, enabling it to move rapidly through the system and quickly locate refrigerant leaks
  • Trace-A-Gas can detect much smaller refrigerant leaks than other methods: it is up to 100 times more sensitive than leak detection spray and can detect leaks of less than 5 grams a year
  • Trace-A-Gas tests all areas of the system, including insulated or difficult-to-access pipework where leak detection spray cannot easily be used
  • Using Trace-A-Gas provides real time results: spend less time on site
  • Using Trace-A-Gas can reduce costs by avoiding the need to re-work
  • Suitable detection can quickly identify the Trace-A-Gas product, enabling engineers to easily locate a leak within refrigeration systems
  • Non-flammable, non-toxic and safe for the environment
