Ultraviolet Germicidal Irradiation (UVGI) is a disinfection method that uses short-wavelength ultraviolet (UV-C) light to kill microorganisms such as fungus, mold, mildew, and bacteria. The application of UVGI to disinfection has been an accepted practice since the 1950’s and is used in a variety of applications such as food, air, and water purification. In recent years, UVGI has found renewed application in air purifiers.
Adding UV lighting to a cooling unit increases overall indoor air quality while improving the performance of the unit. Specifically, the UV light option will protect your unit from mold and other bacterial growth.
Commonly used in HVAC application, this UV disinfection method uses short-wavelength ultraviolet (UV-C) light to kill microorganisms. When exposed to UV-C, DNA begins to degrade and eventually becomes so damaged that it is no longer usable. As mold, fungus, or bacteria are exposed to UV-C, their DNA degrades until they are no longer able to reproduce, and they eventually die. While, UV-C light ranges from 200 to 300 nm, our UV-C light uses an optimal frequency of 254 nm.
Air handlers are particularly susceptible to microorganism growth. Fungus, mold, and bacteria can be pulled in from the cellar or outside. Once inside the unit, the organisms have a perfect place to grow due to the moisture built up in the compartment; from there, the organisms are pushed back into the cellar. Our UV lighting system is designed as an add-on feature that will target the buildup of these microorganisms.
The bulb is positioned inside the evaporator compartment such that the evaporator coil and drip tray are exposed directly to UV light to ensure that these components stay unclogged and are running at optimal efficiency, which improves overall system performance. The transformer box and UV bulb can be mounted to any access panel on the evaporator side of the cooling unit, depending on the blower orientation. With this arrangement, the UV light never comes into contact with wine bottles in the cellar.
