Sterilight SV50 Certified High-flow Light Commercial UV - Discontinued
The SV50 is well suited to very high-flow light commercial water treatment applications where a USEPA certified model is desired or required. It is also a popular choice for bed and breakfast facilities, rural resorts and lodges, etc. The Sterilight SV50 is certified to 50 gallons per minute at a UV dose of at least 40,000μWs/cm2.

The UV lamp, which is enclosed in a quartz sleeve, produces ultraviolet light that destroys waterborne pathogens such as bacteria and viruses by penetrating the cell wall and deactivating the DNA so they are unable to reproduce. The UV lamp should be replaced annually. For more information on the removal of various contaminants by ultraviolet purification, please CLICK HERE.

Which Sterilight Model is best for your home is determined largely by the level of contamination and the maximum flow rate required in your home. Pre-filtration (down to 5 micron level) to remove sediment and other general contaminants is required to ensure that an adequate dose of ultraviolet light reaches the microorganisms and to ensure complete disinfection. Optional in-line flow restrictors, emergency solenoid shut-off valves, and UPS back-up power supplies can be added to your system for added protection and functionality.

* For most applications, a UV dose of at least 30,000 μWs/cm2 is recommended. This is considered an "industrial" dosage. NSF-certification (Platinum SPV Series) is based on a minimum dose of 40,000 μWs/cm2. All flow rate recommendations are based on 95% UV transmittance (UVT) and maximum recommended lamp age (12 months).
** NSF Certified

Recommended Pre-treatment

All UV sterilizers required sediment pre-filtration to reduce or eliminate the possibility that a targeted contaminant could "hide" behind a sediment particle in the "shadow" of the UV light and therefore not receive a full dose of UV light. Accordingly, the manufacturer strongly recommends sediment pre-filtration down to a level of 5 microns or smaller. Water exceeding 120 ppm in hardness (7 grains per gallon) should be softened to reduce the risk that hard water mineral scale will build-up on the UV sleeve thereby reducing UV light distribution into the UV chamber. Similarly, iron levels exceeding 0.3 ppm should also be treated to prevent staining of the UV sleeve. Elevated levels of certain other contaminants, such as tannins, can cause a reduction in UV transmittance (the ability of the water to transmit UV light). If the UV transmittance (UVT) of your water is less than 75% after the above-mentioned pre-treatment, activated carbon filtration may be desirable to improve UV transmittance. The majority of deep wells have a UVT of 85% or greater. If your UVT is unknown, select a model with a higher flow rate capacity then you feel you will really require (this will provide a higher UV dose at your desired flow rate), or add an activated carbon pre-filter to your system. We recommend the following pre-filter equipment:

WH1B+ 5 Micron Sediment Pre-Filter Package excellent overall sediment pre-treatment to 5 micron level	WH2 Sediment & Activated Carbon Pre-Filter Package sediment pre-treatment to 5 microns and improves UV transmittance by removing tannins and other contaminants that reduce UVT	WH5 Iron Reduction Filter Package very cost effective iron pre-treatment filter for iron levels ranging from 0.3 to 5.0 ppm

Recommended Accessories

We recommend that all Sterilight UV Systems be equipped with a flow restrictor to ensure that you do not exceed the maximum flow capacity of the system. All Platinum SPV Series (NSF Approved) models come with a flow restrictor. For all other models, a flow restrictor can be purchased separately. You should generally choose a flow restrictor rated for slightly less flow than the UV sterilizer based on a UV dose of 40,000 μWs/cm2. For more details, review our Sterilight flow restrictors page.

Many Sterilight models can also be equipped with an emergency solenoid shut-off kit. In the event of a power failure or electrical outage to your home, your UV lamp in your UV system will lose power. This could leave your home unprotected if someone turns on a water faucet. Some bacteria and other waterborne pathogens can also swim past an un-powered UV lamp and reach the downstream portion of your water system and therefore not receive a dose of UV light once the power is restored. The same situation could occur in the event of a UV bulb failure or in the event of a reduction in UV lamp output (drop in UV intensity below safe dosage level). The solenoid emergency shut-off valve is normally installed at the output of your UV system and will physically close a valve in the event of a bulb burn-out or power failure, thereby preventing any contaminant from passing through the system untreated. This feature will also turn off the water supply if there is a UV intensity loss (for models equipped with a UV intensity monitor). This kit is highly recommend for all homes with a known bacterial, virus, or cyst contamination problem, and for all homes with an electrical supply that is prone to frequent outages. Various valve sizes are available. For more details, review our Sterilight solenoid valve kits page.

Installation

Installation is straightforward for any licensed plumber or a homeowner with some plumbing experience. Plumbing connections are standard NPT thread as specified in the model specification. It is recommended that standard manual shut-off valves be installed before and after the UV sterilizer. Optional flow restrictors and emergency solenoid shut-off valves are available. The electrical supply is obtained from a standard 110-120v electrical outlet (some models can be operated at 240v). See notes above regarding recommended pre-treatment. Detailed installation instructions are provided with your system.
