Because of the Inherent Benefits and Endless Possibilities, UV Light Applications Have Become the World’s #1 Choice for Industries That Require Water, Air and Surface Sterilization. Germicidal UV-C Technology (CLEARRAY) Offers Safe, Simple and Cost Effective Solutions! UV-C Light is Used to Help Safe Guard Drinking Water, Food, Food Processing Plants, Hospitals, HVAC, etc.

What Is UV-C Light?

  • A Natural Part of the Spectrum of Electromagnetic Energy Generated by The Sun
  • Effectively Interacts with The DNA of Bacteria and Viruses; Destroying Their Ability to Reproduce
  • Is A Natural Process That Adds No By-Products to Your Water and Requires No Chemicals
  • Is Not Generating Ozone – Ozone Is Injected into Your Hot Tub’s Water Causing Off-Gas Which Will Have a Damaging Effect On Things Like Your Headrests (Pillows), Cover, Caps, Knobs, etc.…
  • UV-C Light Creates NO Chemical or By-Products, Unlike Ozone Generators & Salt Systems, Which Create By-Product (Off-Gas) & Chemical (Bromine or Chlorine)
  • Germicidal UV-C Technology Is Superior to Traditional Germicidal Methods for Sterilizing Bacteria, Fungi and Viruses

The UV Spectrum

UV-A, UV-B, and UV-C are all part of the ultraviolet light spectrum.

Ultraviolet A – Wavelength(nanometers)315- 400, Long Wave, Not Absorbed by The Ozone Layer. Results in Skin Tanning, used in Medicine to Treat Skin Disorders.

Ultraviolet B – Wavelength(nanometers)280-315, Medium Wave, Mostly Absorbed by The Ozone Layer. Has A Very High Penetrating Ability and Results in Sunburn. Prolonged Exposure Is Responsible for Some Types of Skin Disease, Skin Ageing and Cataracts.

Ultraviolet C – Wavelength(nanometers)100 – 254, Short Wave, Germicidal, Completely Absorbed by The Ozone Layer and Atmosphere. Extremely Low Penetrating Ability and Is Completely Absorbed by The Outer, Dead Layer of Skin Where It Does No Harm.

UV-C Light Is Very Versatile, used for Disinfecting Water, Destroying Harmful Micro-Organisms in Liquids, on Surfaces, on Food Products and in the Air.

UV-C Technology (CLEARRAY™) Destroys 99.9% of all waterborne pathogens within Seconds, Without Harmful Side Effects.

United States Department of Agriculture (USDA) Research Study Finds UV-C Lights Improve Quality and Shelf Life of Cut Cantaloupe.

According to the study, “Results indicate that while post-cut application of UV improved shelf life of cut cantaloupe melon, cutting fruit under UV-C radiation further improves product quality.”
More specifically, the study found that UV-C radiation during processing reduced rancidity and improved firmness retention in the stored fruit. It also reduced spoilage microorganisms such as mesophilic and lactic acid bacteria.

“To Reduce Mold Counts in The Room Where We Process Butternut Squash, We Pressurized the Space and Installed Steril-Aire UV-C Lights. We’ve Had a Ten Fold Reduction in Mold Counts, Our Air Quality Has Improved and Our Shelf Life Has Increased Dramatically as A Result”

How UV-C Light (CLEARRAY™) Compares to Salt & Ozone Systems


CLEARRAY™ Ultraviolet Germicidal Disinfection

Ozone System – Corona Discharge Ozone Generator

Salt System – Salt Chlorine OR Bromine Generator


CLEARRAY™ Disinfects Water Instantly by Exposure to UV-C Light Bulb
