35 Watts UV Sterilizer – Water Disinfection System

The 35-watt UV sterilizer from Puritech provides powerful, chemical-free water disinfection using ultraviolet (UV-C) technology. This inline system uses a high-output UV lamp to attack the DNA of bacteria, viruses, and other microorganisms, preventing them from reproducing and making your water safer to drink. UV disinfection treats water without adding chemicals, which means that there’s no taste or odour, and it’s ready for use immediately after treatment.

Whether installed as post-treatment after a filtration system or as part of a comprehensive water purification system, this UV sterilizer helps you maintain clean, microbiologically safe water with minimal ongoing maintenance and straightforward operation.

How UV Water Sterilization Works

Ultraviolet sterilization uses UV-C light (short-wave ultraviolet) to disrupt the DNA and RNA of microorganisms. As water flows past the UV lamp inside the sealed stainless-steel chamber, living organisms are exposed to germicidal wavelengths that prevent them from reproducing. Because a microorganism must reproduce to cause infections, this effectively neutralises up to 99.99% of harmful bacteria and pathogens without the use of chemicals or byproducts.

Unlike chemical disinfectants, UV systems don’t alter the water’s taste or odour, and they avoid corrosion issues linked to chlorine. As long as water is properly pre-filtered to remove large particulates, the UV system can deliver continuous protection without waste or ongoing chemical handling.

Key Benefits

• Chemical-free disinfection: Sanitises water without chlorine, ozone, or additives.
• High microbial reduction: UV-C light effectively inactivates a broad range of microorganisms.
• Low maintenance: Only periodic lamp and quartz sleeve cleaning/replacement needed.
• No taste or odour changes: Water remains clean and natural without off-flavours.
• Compact design: Standard stainless body fits easily into treated water lines.

Technical Specifications

Recommended Applications

This 35-watt UV sterilizer is ideal for:

• Post-RO water disinfection, where microbial control is essential after reverse osmosis treatment.
• Domestic water systems to ensure bacteria-free water for drinking and cooking.
• Commercial kitchens and cafes need a safe water supply.
• Water bottling and storage tanks to control microbial growth.
• Well or borehole water post-filtration to prevent harmful microbes.

Note that UV sterilizers don’t remove heavy metals, salts, or chemical contaminants — they should be used in combination with proper pre-filtration for full water quality protection.

Installation & Maintenance Tips

1. Install after sediment and carbon filters so water entering the UV chamber is clear and particles don’t block UV penetration.
2. Replace the UV lamp annually — germicidal effectiveness decreases over time, even if the light still appears on.
3. Clean the quartz sleeve regularly during lamp changes to maintain transmission and performance.
4. Ensure electrical safety with proper bonding and a dry environment for the ballast and connections.

Why Choose the 35 Watts UV Sterilizer?

For reliable water disinfection without chemicals, this UV sterilizer provides effective microbial control and low running costs. Because it delivers continuous protection with minimal maintenance, it’s a smart addition to domestic and commercial water systems where safety and peace of mind are priorities.
