Sterilight Silver Plus Series Ultraviolet (UV) Sterilizers

The Sterilight Silver Plus Series is well suited to point-of-use water treatment and post-RO disinfection to kill bacteria (including coliform and e.coli), viruses, cryptosporidium, giardia, and a wide range of other microbioogical contaminants. The larger Silver Plus Series models, specifically the SSM-24, SSM-37, and SSM-39, can also be used for whole house applications. The Silver Plus Series is the most economical model line-up that we offer that features a UV intensity monitor and a powered solenoid output. It is an excellent choice for applications with a known bacteria or other microbiliogical contamination problem.

All Silver Plus Series units feature a stainless steel reactor chamber, a fire-polished domed quartz sleeve, and Sterilight Sterilume™-EX coated low pressure germicidal UV lamp which can be conveniently changed without interrupting the water flow. The UV lamp provides a 4-log (99.99%) reduction of bacteria, viruses, and protozoan cysts (cryptosporidium and giardia) at the specified maximum flow rates. Lamp life is 9,000 hours (1 year).

The Silver Plus Series electronic "ICE" controller features a switchable power supply that automatically detects line voltage between 100-240 volt and adjusts its operating settings accordingly. It also features a convenient display which indicates % UV output, remaining lamp life, and total days of operation. Coupled with a true 254nm UV intensity monitor housed in a stainless steel enclosure, the Silver Plus Series units continuously monitor the UV output and warn you of any changes in water quality or if the water becomes unsafe to drink. The Silver Plus Series systems also come with a powered solenoid output that allows you to connect an emergency solenoid valve shut-off kit (sold separately) directly into the controller. See below for more information.

Pre-treatment Requirements:

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 or manganese levels exceeding 0.05 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

Accessories:

The Sterilight Silver Plus Series can be equipped with a flow restrictor to ensure that you do not exceed the maximum flow capacity of the system. We recommend that you choose a flow restrictor rated for slightly less flow than the UV sterilizer based on a UV dose of 40 mJ/cm2. For more details, review our flow restrictors page.

The Sterilight Silver Plus series 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.
