Glass quartz sleeve for UV 12W

The QT3-500 is a precision-crafted quartz sleeve designed to fit 12 Watt UV sterilizers. Measuring 300mm in length, it acts as a protective barrier between the UV lamp and the flowing water, allowing effective disinfection without electrical exposure to moisture. Made from high-grade quartz glass, it ensures maximum UV transmission while protecting the lamp from scaling and breakage.

Product Features

• Length: 300mm

• Material: High-purity quartz glass

• Compatibility: Designed for 12W UV lamps

• Function: Protects UV lamp from water while allowing optimal UV-C light transmission

• Maintenance: Clean during lamp replacement to prevent mineral build-up that can reduce effectiveness

How Does Ultra Violet Light Work?

UV rays can destroy 99.99% of harmful micro-organisms without adding chemicals or changing your water's taste or odour. Ultraviolet light (UV) is a natural part of sunlight and is widely accepted as a reliable, efficient, and environmentally friendly solution for water disinfection. The UV lamp utilizes a particularly efficient UV radiator with a 254nm wavelength to cause immediate death to organisms and eliminate their ability to survive and reproduce.

The water is exposed to UV radiation in a specially designed chamber that allows intimate contact with the UV light source. Bacteria and other living organisms absorb this energy, which destroys or inactivates their DNA, thus preventing them from reproducing. Similarly, chemicals and organic compounds absorb the energy and break down into smaller, more harmless molecules.

The effectiveness of UV light depends on several factors:

• Exposure time of the micro-organism to UV

• Stability of the UV wavelength

• Presence of particles that may block UV rays

• Resistance of certain organisms to UV exposure

It is essential to filter the water before UV treatment to remove particulates and to ensure the quartz sleeve remains clean for optimal light transmission. Always select the correct size sleeve for your UV lamp and sterilizer system capacity.
