Leak Detection for Medium to Large Commercial Systems

Dec. 30, 2015
Leaks will fluoresce green under a flashlight, making them easy to spot.

The Spectroline Complete BigEZ Leak Detection Kit contains everything needed to locate refrigerant leaks in medium to large commercial air conditioning and refrigeration systems — including high-pressure R-410A systems. This method is best when used as part of a preventive maintenance plan, in which the dye is added to a system before a problem has occurred.

How It Works Simply add a small amount of fluorescent dye to the system and allow it to circulate. The dye can be added with the system off or running. The dye/refrigerant mixture will then escape and accumulate at all leak sites.
By scanning the system with a leak detection flashlight, all leaks will fluoresce green, making them easy to spot.
