Pallas (Sita) UV 405 AL2 Ultra Violet System 30w 20 l/min 3/4" Male Connection

he Sita UV Ultra Violet Systems are designed to provide efficient and reliable water purification for your home or business. These stainless steel systems are equipped with a simple power supply and LED indicators to ensure optimal performance and easy monitoring as standard. The green LED indicates the system is working, while the red LED signals a failure, allowing for quick troubleshooting. Higher models have the option of the more advanced AL/2 controller with additional features such as lamp countdown so you never have to worry when the lamp is due for renewal.

Key Features:

•  High-Quality Construction: All chambers are made from 304 stainless steel, ensuring durability and longevity.
• Optimal Performance: Capable of handling a range of flow rates  of 10 litres per minute to 85 litres per minute making it suitable for various applications.
•  Temperature Range: Operates efficiently in air temperatures ranging from 2°C to 40°C.
•  Compact Design: With a chamber lengths from 267mm to 880mm, allows fitting easily into most setups.
•  Easy Monitoring: Simple power supply with green LED (working) and red LED (failure) indicators for straightforward operation. Higher models also offer the AL2 monitor as an option with Lamp Countdown and Audible alarms

Clostridium perfringens is an anaerobic, spore forming bacteria that is widely distributed in the environment and frequently occurs in the intestines of humans and many domestic and wild animals.

Can Clostridium perfringens be treated with UV.

Yes, Clostridium perfringens can be inactivated by UV light, but its spores are highly resistant to this treatment, requiring higher UV doses for complete inactivation compared to vegetative cells. The presence of contaminants in water, such as iron and manganese, can also interfere with disinfection efficacy by reducing the rate of inactivation. Effective UV treatment for C. perfringens, especially spores, depends on the specific UV wavelength used and the overall water quality.

UV ratings on flow rate should be at least 4 times the required or achievable flow rate on site or restrict the flow rate of the UV to 38% of the specified flow rate. However, we recommend having physical blockers in place before the UV rather than rely on the UV alone

• Triple filter would be required
• 5 Micron String Wound Sediment Filter from our SW range
• 1 Micron Polyspun Filter from our PS range
• 0.45 Micron Absolute filter. Depending on Flow Rate required, 2 filters in parallel may be required
