Why Choose Aerial Infrared?

High-resolution aerial imagery allows slight nuances of temperature to be detected. This technology makes underground leak detection and the discovery of insulation deficiencies possible. Both hot water (HTHW) and chilled water (CHWS) systems can benefit from aerial infrared leak detection surveys.

High Temperature Hot Water (HTHW) Leak Detection

High temperature hot water (HTHW), medium temperature hot water (MTHW), and low temperature hot water (LTHW) systems benefit similarly to steam distribution systems in that underground heating lines are almost always visible with infrared imaging, even when no notable problems exist. This is due to heat loss making it’s way to the surface, regardless of the quality of insulation. Problem areas are generally quite evident during an infrared leak detection survey, having brighter white IR signatures that exceed the norm.

Chilled Water Supply (CHWS) Leak Detection

Chilled water supply (CHWS) and Chilled water return (CHWR) lines are usually cooler than the surface temperature and can be surveyed for thermal loss and leaks as well. Chilled water supply (CHWS) and Chilled water return (CHWR) lines are usually cooler than the surface temperature and can be surveyed for thermal loss and leaks, with an associated degree of difficulty in surveying because of the declining temperature difference to that of surface.
