Teton XUV Series is a professional-grade UV clarifier and sterilizer system designed for koi ponds, water gardens, aquaculture systems, and commercial water features where reliable pathogen control and algae elimination are essential. Where standard plastic-bodied UV units lose a portion of their UV output to absorption, the XUV’s metal housing reflects UV-C rays within the chamber — increasing effective dose per pass and delivering measurably better performance at equivalent wattages.
The stainless steel housing on the XUV25S through XUV120S is built for permanent outdoor installation and long-term durability. The XUV16A uses an aluminum housing with equivalent reflectance benefits. All models feature a multi-directional 2″ outlet with a mounting bracket for secure inline installation. A single-lamp, single-chamber design simplifies lamp replacement and reduces the total cost of maintenance compared to multi-lamp configurations.
Five models range from 16W to 120W, covering ponds from 4,500 to 14,000 gallons. All models operate at a maximum pressure of 36 psi / 2.5 bar for compatibility with pressurized filtration systems. Maximum recommended flow rates are specified per model to ensure adequate UV dwell time for effective sterilization. Backed by a 2-year warranty on the ballast and a 5-year warranty on the housing.
UV sterilization process
• Water from the pond pump enters through the 2″ inlet at recommended flow rate.
• Water flows through the UV-C chamber, passing the high-output lamp protected by a quartz sleeve. The metal housing reflects UV-C rays inward, increasing exposure intensity.
• UV-C radiation at 254nm wavelength penetrates the DNA of free-floating microorganisms — algae, bacteria, protozoa — preventing reproduction and causing cell death.
• Treated water exits through the multi-directional 2″ outlet and continues to the filter or back to the pond.
• Flow rate is critical: too fast = insufficient UV dose. Run at or below the recommended maximum flow per model for effective sterilization.
Installation position
Install the XUV Series inline between the pond pump and the filter. The unit must not be submerged — external installation only. Position at minimum 6 ft from the water’s edge. Use the included mounting bracket to secure the unit. The 2″ multi-directional outlet allows flexible plumbing orientation. Close the unused outlet with the appropriate cap. Always disconnect power before performing maintenance.
Clarifier vs Sterilizer mode
A UV clarifier (lower wattage relative to pond volume) destroys free-floating algae — green water control. A UV sterilizer (higher wattage relative to pond volume) additionally suppresses bacterial and protozoan pathogens — recommended for koi ponds with valuable fish. The XUV Series models at maximum wattage (80W/120W) at appropriate low flow rates can operate in sterilizer mode. For koi ponds, consult the sizing guidelines.
