Sterilight Model SC-200 Replacement Parts & Accessories
The Sterilight SC-200 Ultraviolet (UV) water sterilizers are popular and economical choices for less demanding (smaller) whole house water purification to kill bacteria (including coliform and e.coli), viruses, cryptosporidium, giardia, and a wide range of other microbioogical contaminants, where the maximum required flow rate is not greater than 8.0 gallons per minute (GPM) or 30.3 litres per minute (LPM).
The Sterilight SC-200 (part of Sterilights's Cobalt Series) include many popular convenience features including a visual "lamp on" indicator light, audible lamp failure alarm, and LED display that indicates lamp life remaining and total controller run time. They also features a stainless steel reactor chamber, a fire-polished domed quartz sleeve, and Sterilights' popular Sterilume™-HO coated low pressure germicidal UV lamp which can be easily changed without interrupting the water flow. It also incorporates Sterilight's Cobalt controller which automatically senses line voltage between 100 and 240 volts for consistent UV output and performance in varying electrical operating conditions.
The SC-200 does NOT include a UV intensity monitor and it CANNOT be connected to an emergency solenoid shut-off valve. If either of these features appeal to you, we recommend that you consider the SCM-200.
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:

*Note: Maximum recommended flow rates based on 95% UV transmittance. Actual dosage depends on flow rate, water quality, and maintenance (cleaning ov UV sleeve). UV dosage will be lower when the UV transmittance capacity of the water drops below 95% - if in doubt, select a model rated for a higher flow rate than you actually require. We recommend a UV dose of 40 mJ/cm2.
