NWTS-UV5-21 UV Sterilizer: Advanced Water Purification with Reliable 21 GPM Flow and Lightlock Technology

The NWTS-UV5-21 UV Sterilizer from Water Softener Plus offers a cutting-edge solution for effective water sterilization in residential or light commercial water treatment systems. Unlike traditional filtration, this ultraviolet equipment uses Lightlock Technology to ensure maximum germicidal efficiency and safety. Designed to handle up to 21 gallons per minute, it delivers consistent, chemical-free purification that protects your water supply from harmful microorganisms.

Key Benefits

• Provides chemical-free disinfection that eliminates bacteria, viruses, and other pathogens
• Maintains high flow rate of 21 GPM, ensuring minimal pressure loss and steady water supply
• Enhances system safety with Lightlock Technology that prevents UV exposure and confirms lamp operation
• Reduces maintenance frequency with durable components engineered for long-lasting performance
• Integrates seamlessly into existing water treatment setups for improved water quality
• Offers energy-efficient operation to keep running costs low
• Compact design and moderate weight make installation straightforward in various environments

How It Works

The NWTS-UV5-21 sterilizer uses ultraviolet light at a specific wavelength to disrupt the DNA of microorganisms in the water, rendering them inactive and unable to reproduce. Water flows through the stainless-steel chamber where the UV lamp is housed, exposing the water to germicidal light without adding chemicals or changing taste.

The Lightlock Technology ensures the UV lamp is securely sealed and operating correctly, providing an additional safety layer by preventing accidental UV light exposure. This technology also alerts users if the lamp needs replacement, maintaining consistent disinfection performance.

What to Expect

Once installed, you’ll immediately notice peace of mind knowing your water is undergoing continuous UV sterilization without altering its natural properties. In the first few days and weeks, the system will consistently reduce microbial contamination, contributing to clearer, safer water for daily use.

Over time, the NWTS-UV5-21 requires minimal maintenance—primarily periodic lamp replacement and quartz sleeve cleaning—to ensure optimal function. Its robust build ensures reliable operation for years, making it a trusted component in your water treatment system.

What’s Inside

• Stainless Steel Chamber – Provides corrosion resistance and durable housing for UV exposure
• High-Intensity UV Lamp – Generates germicidal UV-C light for effective microorganism inactivation
