Sterilight Platinum (SP) Series
High Output Ultraviolet (UV) Water Purifiers

Sterilight Platinum Series UV Water Purifier The Sterilight Platinum (SP) Series was designed for whole house and light commercial applications with water flow rates up to roughly 50 gallons per minute (multiple units in parallel can be used for even higher flow rates). Applications include private wells and lake water supplies, camp grounds, hotels, bottlers, aquaculture, hospitals, food, cottages, restaurants, breweries, water systems, laboratories, marine, pharmaceutical, dairies and more.

The Platinum (SP) Series is loaded with features typically found in only expensive commercial units, yet it is available at a very economical price - in fact, many models cost considerably less than competitors' models with far fewer features!

The Sterilight Platinum (SP) Series is based on the feature-laden Platinum™ ICE controller and Sterilight's Flow-Pace™ UV intensity monitor. This combination allows for 2-stage flow pacing where the lamps operate at half power when water is not flowing and full-power when the water is running. This allows the system to operate with minimal power requirements (excellent for applications powered by solar power systems!), at a lower operating cost, and with less heat build-up. The Platinum™ ICE controller provides constant output current and a universal power input (100-250V./50-60Hz.), as well as visually displaying % UV intensity, remaining lamp life, and total hours of operation. The system comes with a set of dry contacts allowing for the external hook-up of a remote device such as a solenoid valve (sold separately - see below), as well as a self-diagnostic check upon start-up, and an RJ-11 communications port. Using high-output, Sterilume™-HO coated low pressure germicidal UV lamps coupled with 304 stainless steel, axial flow sterilization chambers, the Platinum Series provides very high flow throughput capacity in a very compact system. 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 Sterilight Platinum (SP) Series is composed of eight models with treatment capacities ranging from 4 to 39 gallons per minute based on a UV dose of 40 mJ/cm2 (at 95% UVT). We recommend a UV dose of 40 mJ/cm2 for most commercial and residential applications.

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:

Accessories:

The Sterilight Platinum (SP) 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 40,000 μWs/cm2. For more details, review our flow restrictors page.

The Sterilight Platinum (SP) 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.
