The MULTIRAY series is our professional pool UV series based on numerous years of scientific research and R&D activities, optimized for disinfection, chloramine reduction, and crypto/giardia safety in swimming pools. The result is much lower combined chlorine, fewer germs and healthier water, and air quality. Scientific research conducted over the last 10 years, has shown that under normal operation most of the measured combined chlorine levels are composed of organic chloramine compounds in the swimming pools. The MULTIRAY series ensures a low level of organic combined chlorine in the pool water through continuous photolysis with the specially pool-optimized ULTRAAQUA medium pressure lamp technology. The UV lamp can be serviced tool-free. The sensor operates directly in water for accurate output and has a specially developed valve mechanism for cleaning and servicing during the operation in pools, where flow stop is prohibited during opening hours.
The reactor geometries and electronic control systems have been designed to minimize operating costs. The large, flanged connections and body geometry result in very low head loss even at a high flow rate. The intelligent PLC control enables excellent automatic operational efficiency by lamp dimming based on combined chlorine sensing, time of day/week timers, or UV sensor. Material selection and components of high industrial quality guarantee long-term trouble-free operation in the mostly hot, humid, and corrosive pool environments. Our recommendation is to dim and operate the MULTIRAY UV based on a setpoint of combined chlorine measured in real time to save energy. During opening hours, it can be chosen to always maintain a minimum UV dose in the chlorinated water to ensure a secondary barrier against crypto and giardia.
All UV lamps destroy PVC pipes in chlorinated water, which eventually might break. To avoid general problems, the MULTIRAY UV has sufficient steel chamber length to make it possible to install directly in most PVC pipes. To be sure to avoid problems in PVC pipes, additional PE or steel piping can be used, placed one meter from the powerful UV lamps. We also provide optional light blockers, preventing direct UV radiation from escaping from the reactor.
