Micro UV
The PearlAqua Micro debuts the most compact UV system in the world. Highly configurable, this product can be installed directly at the point of use.
Flexible Integration
The Micro platform is designed for integration in the tightest places. It allows for the application of UV technology in treatment processes never thought possible.
UV Intensity Monitoring
UV sensor option available to monitor real-time UV intensity within the reactor chamber for mission-critical applications.
Comprehensive Model Line-Up
4 discrete models available for a broad range of flow rates. Allows the user to optimize based on process water conditions.
Temperature Independent
LEDs do not transfer heat to the water, thus limiting fouling and ensuring a constant UV output regardless of water temperature.

Flow Switch and Interface Board.
To further compliment the Micro 'C' we offer an optional integrated flow switch. This addition benefits the user by only switching on the LED's within the Micro UV disinfection unit when flow is passed through the device therefore saving energy. The flow switch integration removes the need for the system to be constantly on or the need for external control switching and simplistically automates the UV unit and extends its usable lifetime. LED UV units instantly reach kill intensity when switched on giving confidence that no water passes un-treated.
​
The Flow switch and interface board is only compatible with the Micro 'C' range.
Point of Use Water Disinfection with PearlAqua Micro UV-C LED

Point of Use Water Disinfection for Homes and Businesses
In homes and commercial buildings, water is often stored in Cold Water Storage Tanks (CWSTs) and distributed via booster pumps to meet demand. This can introduce risk from biological contaminants, especially when temperatures rise above 20°C or water becomes stagnant. Compliance with ACoP L8, including flushing and regular disinfection, is critical – but not always sufficient.
For water outlets that do not require full-system chemical dosing, point-of-use (POU) disinfection offers a targeted, chemical-free solution. The PearlAqua Micro UV-C LED system provides effective pathogen control including the control of legionella and pseudomonas directly at drinking taps, kitchen sinks, or showers. Simple to retrofit and powered by 12 VDC or with a 230V AC/DC transformer, the PearlAqua Micro integrates seamlessly into domestic or commercial plumbing, delivering germicidal UV light to deactivate bacteria and viruses just before water is dispensed.
For higher flow rate needs, consider the PearlAqua Deca 30C or PearlAqua Deca 24C4, which are ideal for entry-point or multi-outlet disinfection.

Healthcare Water Disinfection and Dental Waterline Safety
In medical and dental environments, where water is used to irrigate, rinse, or clean, microbial contamination can pose serious infection risks. Whether connected to mains supplies or closed-bottle systems, waterlines are vulnerable to biofilm growth. Bacteria dislodged from biofilms can contaminate procedures or be inhaled as aerosols.
The PearlAqua Micro UV-C LED device, with its ultra-small footprint and low energy use, installs at the point of use to inactivate pathogens in-line. Unlike traditional UV systems, this mercury-free LED technology offers instant on/off cycles, low operating temperatures, and up to 10,000 hours of UV lamp life.
For larger-scale installations requiring greater flow, the PearlAqua Deca 30C and PearlAqua Deca 24C4 provide powerful, certified protection.

Pharmaceutical and Laboratory Water Purification Using UV-C LED
In pharmaceutical and laboratory settings, water purity is essential. Type 1, 2, and 3 purified waters must be free from microbial contaminants to protect experiments, procedures, and analyses. Contamination from biofilms or bacteria can compromise results and product integrity.
LED UV-C technology offers a robust solution for safeguarding purified water at the point of use. The PearlAqua Micro enables mercury-free, instant disinfection that complements ultrafiltration, RO, or other purification methods.
OEMs supporting lab and pharma sectors can integrate this advanced technology to enhance product safety and compliance. Learn more on our OEM Solutions page.

UV LED Vending Machine Disinfection and Beverage Water Hygiene
In vending, coffee, and water dispensing systems, hygiene is paramount. The final few metres of water delivery – from filter to tap – are vulnerable to bacterial growth, especially in heat exchanger systems where warm temperatures encourage biofilm formation. This affects not only hygiene but also energy efficiency.
Installing the PearlAqua Micro UV-C LED unit at the point of use ensures clean, safe water enters every drink or vending machine. With compact dimensions, push-fit 3/8” connections, and 12/24V compatibility, it’s ideal for retrofitting.
UV-C LEDs destroy bacterial DNA, preventing replication and biofilm formation. Their instant-on functionality and durability make them perfect for intermittent-use machines.

FAQs: PearlAqua Micro & UV-C LED Water Disinfection
How long does the PearlAqua Micro last? The PearlAqua Micro has a typical operating life of up to 10,000 hours, which only counts when the unit is active. For applications using the unit for a few hours a day, this equates to years of service life. Other models, such as the Micro 12C-450 and Deca 24C4, offer 8,000 and 5,000 hours respectively.
Do I replace the whole unit or just a part? The PearlAqua Micro and Deca 30C are fully replaced at end of life. The Deca 24C4, however, features a replaceable LED module. All units can be returned to LED UV-C Systems Ltd. for free recycling.
What affects the unit's lifespan? Unlike mercury lamps, LED UV-C systems are not affected by on/off cycling. The only factor influencing lifespan is the total time the unit is running. Water quality doesn’t affect lifespan, but poor UVT (ultraviolet transmittance) may reduce disinfection performance.
Is there a way to know when the unit needs replacing? Yes. The Micro with AutoMate (integrated flow switch) and both Deca models have visual LED indicators that display operational status and signal when servicing or replacement is due.
Can I service the unit myself? Yes. The Deca 24C4 includes a user-replaceable module with an instruction manual. Other units require full replacement but are designed for straightforward installation.
What should I do if disinfection performance drops while the unit is still within its lifespan? If performance drops despite the unit being within its expected lifespan, it may require cleaning. Low levels of chlorine or peracetic acid can be flushed through the unit to clean the quartz window and restore performance.
