MP-UVC-45LB
MASSPHOTON
A whole-house water disinfection solution, supporting integration at the main inlet and covering multiple water points including kitchen, bathroom, and laundry. Employs mercury-free UVC LED technology to replace traditional mercury-based systems, offering higher reliability and eco-friendliness for full-chain water protection. Professionally validated for stable operation, providing users with comprehensive “whole-house + all-endpoints” safe water assurance.

The module is meticulously designed with a compact and streamlined structure, making it easy to integrate into existing water systems. At the heart of the module are high-quality UVC LED chips that emit ultraviolet light at a specific wavelength (usually around 275nm) which is highly effective in destroying the DNA and RNA of microorganisms such as bacteria, viruses, and protozoa. The UVC LED chips are carefully arranged to ensure uniform irradiation of the flowing water, maximizing the disinfection efficiency.
The module also features a well-engineered water channel that is designed to optimize the flow rate and residence time of the water within the irradiation zone. This ensures that the water is exposed to the UVC light for an adequate period to achieve complete disinfection. The materials used in the construction of the water channel are resistant to corrosion and chemical degradation, ensuring the longevity and reliability of the module.
The advantages of using our UVC LED Flowing Water Disinfection Module are numerous. Firstly, it provides a chemical-free disinfection method, eliminating the need for harmful chemicals such as chlorine, which can have negative impacts on human health and the environment. This makes it an ideal choice for applications where chemical-free water treatment is essential, such as in drinking water supply systems.
Secondly, the module offers high disinfection efficiency, effectively eliminating a wide range of microorganisms, including those that are resistant to traditional disinfection methods. This ensures the safety and quality of the water, reducing the risk of waterborne diseases. Finally, its compact size and ease of integration make it a versatile solution that can be used in a variety of water systems, from small-scale domestic applications to large-scale industrial installations.
