    Why outperform Gamma, Tetra,
       Aqua Ultraviolet, Cyprio, Supreme, Cal Pump, & others.**

Harnessing the full power of the UV lamp requires precise engineering! The lamp’s length, UV-C output performance, and
position inside the UV exposure chamber all effect a UV’s operating capacity.

Size does matter!

SMART UVs are generally larger in size than competing UVs (as shown to the right).This means they offer greater UV exposure--utilizing the UV lamp to its maximum potential! SMART UV water flow rates reflect true equipment capacity and real application conditions…they are never exaggerated!

  UV Water Flow Rate Based On 90% UV Transmissibility
  The Manufacturer's Suggested UV Water Flow Rates

UV Performance Standards
• 30,000 µWs/cm2
• UV-C Transmissibility
• UV Water Flow Rate		 • UV Lamp Length
• UV-C Output
• UV Exposure Chamber Dimensions
  		Flow Rates that Match True UV Capacity

 Emperor Aquatics, Inc. is the only manufacturer that supplies you with
UV water flow rates that represent true equipment capacity in actual application conditions!

SMART UV water flow rates take into account poor UV light transmittance through “green water”—one reason why our flow rates are so much lower than competing UV brands.

We encourage you to compare our information with what you hear from any of our competitors. Our information
makes sense because it’s based on science and fact. It is meant to help you, never to confuse you!
