Two links are shown below to assist you with both selecting
the correct Delta UV Series and then the correct Model within
that Series for your application. It is recommended
that you first determine which UV Series is correct for your
application (more than one may be correct for your application)
and once this is determined, then select the proper size system
within your selected Series. Need some help selecting the
correct system? Contact Delta UV Customer
Service and we will be glad to recommend the proper system
for your application

Series Model Selection Chart
Selecting the proper Delta UV Series and Model for your application is a simple matter. The effectiveness of the UV unit to do its sanitizing job is directly related to proper water flow trough the UV system's wet chamber. If water flows in and out of the wet chamber too quickly, the water and its contaminates will not be exposed to the UV-C rays emitted by the UV lamp inside the unit's wet chamber for a sufficient amount of time to achieve proper bacteria eradication. Thus matching the flow rate of the circulation pump to the proper size Delta UV system is most important to achieve proper killing power from the UV system..
The piping size, the length of piping from the water vessel to the equipment all contribute to different flow rates for any given pump. However, you can use the chart below to determine which Delta UV Model is right for your application. Even though the pairings of different pumps to different Delta UV units shown below is proper, due to the relative small cost difference between a smaller UV unit and the next larger size unit, you may wish to consider moving up in size to ensure the absolute maximum performance from the Delta UV system for your application.
Once you have determined the Horsepower (HP) of the circulation pump (found on the motor nameplate on the pump motor) use the chart below to select the proper Delta UV Model.
