Aqua Ultraviolet SL 200-Watt Units are ideal for both residential and commercial use; our UV sterilization process is able to sterilize not only water but other opaque liquids. This process harnesses the power of the sun, using the same germicidal rays it produces but hundreds of times stronger to sterilize water without altering its taste, chemistry, smell, appearance, or Ph. This offers users a reliable, cost-effective, and environmentally friendly alternative to traditional chemicals.
