Operating principle
The UV sterilizer Helix Max clears the water with the help of ultraviolet radiation. This radiation is
emitted by a special lamp. The UV-C radiation kills all forms of life that is directly exposed to the
radiation – microalgae, bacteria, protozoa and other parasites. The result is cristal clear water and
healthy fish.

Special features
Spiral water flow: The unique spiral water flow and the big volume of the Helix Max units ensure an
optimum water clarification. The water is directed in a spiral way around the quartz tube with a long
contact time. Due to this, the UV-radiation is used with maximum efficiency.
Rotable connections: The inlet and outlet connections of the Helix Max can be rotated by 360°. This
saves space and fascilitates the installation.

Sizes/technical data
Helix Max sterilizers are produced in 6 sizes:
5 watts, 9 watts and 11 watts with 2 m cable for fresh and saltwater aquaria. 18 watts, 36 watts and
55 watts, with 10 m rubber cable and electronic ballast for garden ponds and for fresh and saltwater
aquariums. A higher UV output and a longer life span of the UV lamps are ensured by the electronic
ballasts.
For the different applications, we recommend different aquarium/pond sizes and flow rates. In garden
ponds, the recommended flow rates will not result in a sterilization, but the water is clarified by killing
the microalgae.

Safety advice
The radiation of the UV-C lamps is dangerous. Direct contact with eyes or skin can result in
irreversible damages. Therefore, the unit must always be switched off before it is opened.
The units Helix Max 5, 9 and 11 watts are suitable for indoor use only. The units may only be switched
on when the water flow is on. If used on a garden pond, the units have to be switched off and
removed during winter to prevent damages from frost. The units may not be submerged or operated
under water.

Connection
The Helix Max are supplied with transparent connection pieces. This allows to control the function of
the bulbs – there is a blue light when the UV bulbs are on.
