HW UVC 500 / 15W

The unique construction of the HW UVC 500/15 ensures a far more efficient irradiation of the flowing water than competing products can offer. The efficiency is achieved by the passage of water only 3-4 mm around the UVC source and at the same time the outer tube is coated on the inside for the greatest possible reflection of the radiation. These measures make the UVC 500/15 almost twice as efficient as similar products with the same wattage.
The innovative solutions mean that you can just have UVC UVC 500/15 on for half the time and achieve the same effect. The savings on the energy bill speak for themselves.
The visible light that penetrates through the glass sheath is completely harmless and corresponds to the emission from an ordinary old-known fluorescent tube.
When you use UVC 500/15 in the fight against bacteria and algae, only the free-floating organisms die. Your biological filter system and the gram-positive bacteria that live here and which are vital for the nitrification process, yes they are not affected!
Most skylights / luminaire boxes / lids above the aquarium have room for the UVC models. When UVC is on, a bluish light is seen, which very elegantly illuminates moonlight, which is why UVC 350/10 can be used during the on / off clock during the night hours and thereby solve several tasks simultaneously. If you think it lights up too much, the UVC tube can be covered with tinfoil.
With a competing product of 11 watts UVC you would have to have it turned on 24/7 to achieve the same power and achieve an electricity consumption of 264 Watts. With UVC 500/15 you can settle for 6 hours = 90 Watt.
If your aquarium water is generally cloudy, you will experience a significant difference after just a few days!

The effective protection against germ contamination, bacterial water clouding and floating algae in marine and freshwater aquariums.

Aquarists know the problems: Despite careful care, their fish swim “cloudy water” or the long-awaited, successful propagation of their fish fails due to the fungal growth on the fish eggs…
The reason for this is usually a contamination of the aquarium water through fungal spores, bacterial microorganisms, water cloud or floating algae.

With the use of an hw®-UV-Watersterilizer their spread will be prevented safely and without any harmful side effects. In the mini-ecosystem aquarium, the bacterial load is many times higher due to the very limited water volume in comparations to nature environments. Without the use of an hw®-UV-Watersterilizer the load of unwanted microorganisms will steadily increase, leaving totally the natural balance.With the installation of an hw®-UV-Watersterilizer you can ensure a microbiological balance in your aquarium system and create near as possible natural conditions.

hw®-UV-Watersterilizer are a special construction that has proven itself more than 100,000 times in research institutions, in the commercial sector and in ambitious hobby aquaristics.

Due to the extremely large contact surface to the direct UV-C radiation source in connection with a small layer thickness (3 to 4 mm) of the water to be irradiated, such an intensive irradiation is achieved as would otherwise only be achieved by devices with wattages almost twice as high.

In a closed radiation chamber, the aquarium water is directed past an artificial, high-intensity UV-C radiation source. The bacterial microorganisms, cloudy water and floating algae in the water are so intensively irradiated with UV-C radiation that they are killed directly or are no longer capable of cell division and die.

The special glass jacket used acts as a UV-C radiation reflector, which reflects the UV-C radiation back into the radiation room. In this way, the intensity of the radiation is significantly increased again and an increased power yield is realized. At the same time, the special glass jacket enables a precise function check of the UV-C burner as well as a status check of the radiation room.
The visible light penetrating outwards is completely filtered and completely harmless (corresponding to the light emission of a normal neon fluorescent tube …).

When UV-C radiation takes place, sterilized water from the hw®-UV-Watersterilizer constantly mixes with germ-rich water from the aquarium (nitrification bacteria in the filter and in the bottom of the aquarium are not damaged by UV-C radiation). So it is not a complete “disinfection” of the entire aquarium water, but a strong germ reduction (maximum germ reduction in the entire aquarium system approx. 98%) of the aquarium water.

This is extremely important and necessary, because the germs remaining in the water (approx. 2 to 3%) maintain the antibody production of the fish against pathogens and strengthen their immune system.
