5 What is Cloud Hunting?
When refrigerant leaks from a system, it does not disperse evenly in the air. The
concentration of refrigerant is usually higher near the source of the leak. The density
of refrigerants is also different than that of air, so it tends to form “clouds” in the air,
typically closer to the floor. These clouds are colorless and odorless for most
refrigerants. When leak checking with a traditional leak detector, it will likely alarm
when walking into a refrigerant cloud. This does not help you find the leak, because
the cloud may not be near the leak source.
D-TEK Stratus uses patent-pending technology to display the refrigerant concentration
in the air in parts per million (ppm). This allows you to read the display and follow the
number to find areas of higher concentration, leading you straight to the leak source.
