U.V. DISINFECTION (depending on the hot tub model's features)
Ultraviolet rays (UV-C) allow water to be disinfected without using chemicals. When
bacteria, viruses and protozoa are exposed to wavelengths between 200-300
nanometres (range C), these waves become a quick and effective germicide,
preventing microorganisms from reproducing and contaminating the water.
Moreover, disinfection with UV-C rays is considered environmentally friendly,
chemical-free, and highly effective at disinfecting the water and protecting it
against harmful microorganisms. This disinfecting component is located after the
filtration pump and before the electric heater. A lamp inside the unit emits UV-C
rays that disinfect the water as it flows through it.
