For commercial water treatment applications, we highly recommended that multiple units in parallel flow configuration be installed to provide at least partial redundancy. For instance, if you need a flow rate of 50 gallons per minute, installing 2 units rated at 30 GPM each (in parallel flow configuration) will often cost about the same but provide at least partial redundancy to reduce downtime during maintenance or fault.
Many commercial applications require third-party performance validation (usually NSF/ANSI Standard 55 Class A, or U.S. EPA UVDGM). Check with your local regulatory body / health authority before selecting a model so you can ensure that you select an appropriate validation if required for your application.
* Please note that the flow rate capacities specified above are based on a UV dose of 40 mJ/cm2 at 95% UV transmittance (UVT) unless otherwise noted. UV transmittance is a measure of the clarity of your water and the ability to pass UV light through it. 95% UVT should be considered rather ideal. If your UVT is less than 95% or you are unsure of your UV transmittance (it has not been tested), we recommend that you choose a UV unit with roughly 2 times the flow rate capacity that you need (this equates to a UVT level of about 70-75%). This will ensure that your water can be safely disinfected in the event that your UV transmittance is less than optimal. If your UVT is known to be less than 75% or your source water is highly coloured or cloudy, please call us for pre-treatment and sizing assistance (toll free 1-866-376-2690).
