|Mounting location in your air conditioner system.|
There are a number of clear advantages in this regards of the Air Probe Sanitizer. For one thing, there are many, many different makes, models, sizes, and designs of air handlers (HVAC systems), and as a consequence, we often we have to make a custom-length Air Probe Sanitizer (or a special lamp spacing) to fit a particular air handler. And not only is there usually no extra charge should a custom length, lamp spacing, or mounting configuration is required, but many custom Air Probe Sanitizer lengths and different designs are stocked.
BEWARE. Inferior, similar-looking "in-duct" UV products have another major drawback: fixed designs with little flexibility. The main problem is that their dual-lamp model (used on almost all residences without exception) have a fixed lamp spacing. They just plain won't properly fit some air handlers, no matter what. And so they just don't do the job. And the only way you can make their unit work on some air handlers is to chop some holes in the sheet metal. Some homeowners don't like that, because it voids the warranty on their air handler.
Furthermore, on top of the fixed-lamp-spacing limitation, there's also only one mounting design, either for single-lamp or dual-lamp models.
You just don't stick one in a duct somewhere, or blindly mount it "on top" of the evaporator coil. If the lamps aren't mounted on the COLD AIR SIDE of the evaporator coil, and close to the coil so as to fully illuminate it, then the job is not done right. The flexibility of the different Air Probe Sanitizer designs and lamp spacings ensures a job done right, and a happy customer, every time.
