1-Year Maintenance Kits

Replacing just the lamp is a rookie mistake. Scaled quartz sleeves block 50% of UV light, and aging ballasts will instantly burn out new lamps. Our comprehensive 1-Year Kit includes the UVC Lamp, High-Purity Quartz Sleeve, Electronic Ballast, and O-rings for a 100% reliable rebuild.

* Note: Flow rates are calculated based on standard clear water transmittance (UVT > 95%). For wastewater or low UVT applications, please contact engineering for custom sizing.
* Custom configurations (e.g., L-shape, U-shape, specific flange standards) are available upon request.

Process Engineer's Note: Flow Rate Derating based on UVT

The maximum flow rates listed assume a UV Transmittance (UVT) of >95%. If your feed water has a lower UVT (e.g., 85% in wastewater applications), the UV light cannot penetrate as deeply. You must derate the maximum flow rate by approximately 40% to maintain the required 30 mJ/cm² lethal dose. Never undersize a UV reactor.

// MODULE-04 / PIPING & CONFIGURATION

Custom Flange Orientations.

Don't cut your existing pipelines to fit a standard UV reactor. WANDONG manufactures custom inlet and outlet orientations to perfectly match your site's P&ID layout.

Deconstructing the DNA Disruption.

How do we achieve 99.99% sterilization in just 0.2 seconds? Explore the physics of 254nm UVC irradiation and the heavy-duty components that make it possible.

254nm UVC Light Disrupting DNA Molecular Bonds for Sterilization

254nm UVC Irradiation

1. 254nm UVC Irradiation

The core mechanism. High-intensity UVC light at exactly 253.7nm penetrates the cell walls of microorganisms. It instantly destroys the molecular bonds of their DNA and RNA, rendering them completely unable to reproduce or cause infection. 99.99% kill rate in under 0.5 seconds.

2. High-Transmittance Quartz Sleeve

The lamp never touches the water. It is housed inside a high-purity quartz glass sleeve that allows >90% of the UVC light to pass through. This protects the electrical components while maximizing the lethal dose delivered to the water stream.

3. SUS304/316L Polished Chamber

The reactor body is constructed from food-grade stainless steel. Crucially, the interior is mirror-polished. This reflects any unabsorbed UV light back into the water column, amplifying the total UV dose and eliminating dark spots.

4. Matched Electronic Ballast

A UV lamp is only as good as its power supply. Our dedicated electronic ballasts provide the exact starting voltage and stable running current required to guarantee the lamp's full 12,000-hour lifespan without premature burnout.

// MODULE-07 / PATHOGEN ERADICATION

100% Kill Rate. In Milliseconds.

Stop relying on slow-acting chlorine. Our high-intensity UVC reactors achieve total pathogen destruction in a fraction of a second.

100% Eradication Time (Seconds) at 254nm

Pathogen Category	Specific Microorganism	Time to 100% Kill (Sec)
Bacteria	E. Coli (大肠杆菌)	0.36 s
	Legionella (嗜肺军团菌)	0.20 s
	Salmonella (沙门氏菌)	0.51 s
Viruses	Influenza Virus (流感病毒)	0.23 s
Viruses	Rotavirus (轮状病毒)	0.52 s

// MODULE-06 / OPERATING LIMITS

Water Quality Requirements.

UV light travels in straight lines. If the water is cloudy or scaling occurs on the quartz sleeve, the sterilization fails. Strict adherence to these feed water limits is mandatory.

Maximum Operating Pressure	1.0 MPa (10 bar / 145 psi)
Water Temperature Range	5°C - 40°C (41°F - 104°F)
UV Transmittance (UVT)	> 75% (Ideally >95%)
Total Suspended Solids (TSS)	< 10 mg/L
Turbidity	< 1 NTU
Hardness (as CaCO3)	< 120 mg/L (To prevent sleeve scaling)
Iron (Fe)	< 0.3 mg/L
Manganese (Mn)	< 0.05 mg/L

Installation Warnings

Never look directly at the UV lamp while it is illuminated. Severe eye damage will occur.
Do not touch the quartz sleeve or lamp glass with bare hands. Fingerprints will burn into the glass and reduce UV output.
Ensure the control panel is protected from rain and direct moisture.

Pre-Filtration is Mandatory

UV light cannot penetrate solid particles. If your water contains high turbidity or suspended solids, bacteria can "hide" in the shadows of these particles and survive the UV chamber.

Always install a 5-micron (or finer) filter cartridge immediately upstream of the UV system to guarantee 99.99% sterilization.

// MODULE-10 / MANUFACTURING QUALITY

Heavy-Duty Craftsmanship.

Don't risk a 10-bar pipeline blowout with cheap stamped metal. WANDONG reactors are built for decades of continuous industrial abuse.

Forged Flanges (Not Stamped)

We use solid forged SUS304/316L flanges, significantly thicker than standard stamped alternatives. Guarantees zero deformation and leak-free operation at 1.0 MPa.

TIG Fish-Scale Welding

Every joint is manually TIG welded by certified pressure-vessel artisans. The distinct "fish-scale" pattern ensures maximum penetration and structural integrity.

Electropolished Interior

The internal chamber is electropolished to a surface roughness of Ra < 0.4µm. This eliminates microscopic crevices where bacteria can hide, and maximizes UV reflection.

// MODULE-11 / PROVEN IN THE FIELD

Powered by WANDONG.

We don't just sell components; we build the heavy-duty systems that rely on them. Our UV reactors are the final security barrier in our own high-purity RO skids deployed globally.

The Integrator's Advantage

Because we use these exact UV systems in our own EPC projects to guarantee zero-bacteria effluent, they undergo rigorous internal quality control that pure trading companies simply cannot match.

// MODULE-15 / TECHNICAL FAQ & WARRANTY

Hardcore FAQ.
Engineering-Grade Answers.

Why do I need to buy the "Maintenance Kit" instead of just a lamp?

Because replacing just the lamp guarantees failure.

Over 9,000 hours of operation, the quartz sleeve develops microscopic scaling that blocks UV light. Even with a brand new lamp, a dirty sleeve means your water isn't being sterilized. Furthermore, aging electronic ballasts provide unstable voltage, which will instantly burn out your new lamp.

Our 1-Year Kit provides a new Lamp, a pristine Quartz Sleeve, a matched Ballast, and fresh O-rings. It's the only way to guarantee another year of 99.99% sterilization.

Does UV sterilization leave any chemical residue in the water?

Absolutely not. UV is a 100% physical process. It adds no chemicals, creates no harmful disinfection by-products (like THMs created by chlorine), and does not alter the taste, odor, or pH of the water. This makes it the perfect choice for food & beverage and RO pre-treatment.

How often should I replace the UV lamp?

Our industrial UVC lamps are rated for 9,000 to 12,000 hours of continuous operation (roughly 12 to 16 months). Even if the lamp is still emitting visible blue light after this time, the invisible UVC intensity will have dropped below the threshold required for 99.99% sterilization. You must replace the kit annually.

Can I install the UV system vertically?

Yes, our stainless steel reactors can be installed horizontally or vertically. However, if installed vertically, the water flow must enter from the bottom and exit from the top to ensure the chamber remains completely full of water and to prevent air pockets from exposing the quartz sleeve to overheating.

What is UVT and why is it critical for UV sizing?

UVT (UV Transmittance) measures how much UV light can penetrate through your water. Pure RO water has a UVT of >95%, meaning the light travels far and sterilizes effectively. Wastewater might have a UVT of 80%, meaning the light is blocked by dissolved organics. If your UVT is low, you must buy a larger UV reactor to achieve the same 99.99% kill rate.

How do I know if the lamp is actually sterilizing the water?

You can't tell just by looking at the blue glow. For critical applications, we offer an optional UV Intensity Monitor (Sensor). This sensor taps directly into the stainless steel chamber and measures the actual 254nm UVC dosage hitting the water. If the quartz sleeve scales or the lamp degrades, the monitor will trigger a PLC alarm.
