The "in-duct" fixtures are well suited for mounting singularly or in grid patterns along the interior walls of supply ducts or plenums to introduce UV-C to the air-stream in adequate dosages.

They are an ideal choice for mounting close to the coil and drain pan areas to inhibit the growth of mold and mildew in these areas.

These units are available in a variety of sizes and lamp types, both single and double lamp assemblies. Optional reflector styles can aid in directing UV-C at specific areas of the coil and drain pan.

There are in-duct units for large ducting as shown on the right.  These modular units provide high dose UVGI for pathogen eradication.
