Spiral tube incl. Helix Max 18 W 2.0 spacer Aqua Medic

Spiral tube with spacer for Helix Max 2.0 18 W Aqua Medic

The Aqua Medic spiral tube with spacer is an original spare part intended for the Helix Max 2.0 18 W UV-C sterilizer. It is used to replace the unit’s internal spiral when it is damaged, deformed, or has become difficult to clean.

This part plays a direct role in the operating principle of the Aqua Medic sterilizer. The spiral tube guides the water along a helical path around the quartz tube to extend its exposure to UV-C radiation. This controlled passage helps make efficient use of the radiation produced by the lamp.

A spare part suitable for the Helix Max 2.0 18 W

This spiral tube is specifically designed for the Aqua Medic Helix Max 2.0 18 W model. It is supplied with the corresponding spacer to allow installation inside the sterilizer body.

Replacing it with a suitable part helps preserve the water flow path designed by Aqua Medic. A damaged or incorrectly positioned spiral can disrupt the internal water circulation and reduce the quality of its exposure to UV-C radiation.

Role of the spiral tube in the UV-C sterilizer

In the Helix Max 2.0, the water does not simply pass straight through the unit. The Aqua Medic spiral tube forces the water to circulate around the quartz tube containing the UV-C lamp. This path increases the water’s dwell time in the radiation zone and promotes even use of the UV-C light.

The spiral tube should not be confused with the quartz tube. These are two different components: the quartz tube protects the UV-C lamp, while the spiral organizes the water flow around it.

When should the Helix Max 2.0 spiral tube be replaced?

Replacement may be necessary when the spiral shows a crack, deformation, significant wear, or deposits that cannot be properly removed. Intervention may also be useful when the spacer is damaged or no longer holds the part correctly in the unit.

When disassembling the Helix Max 2.0 18 W, it is also recommended to check the condition of the quartz tube and the sealing gaskets. The gaskets must be clean, correctly positioned, and free of cuts before reassembly.

Installation and maintenance tips

Before any intervention, unplug the UV-C sterilizer and stop the water circulation. Empty the unit, then disassemble it according to the Aqua Medic instructions. Carefully remove the old spiral tube without putting stress on the quartz tube.

Clean the accessible surfaces and remove any limescale deposits before installing the new Helix Max 2.0 18 W spiral tube with spacer. Put each component back in its original position, then check the unit for leaks when refilling it with water.

The UV-C lamp must never be looked at directly while it is operating. The sterilizer should only be used when it is fully assembled and connected to the aquarium’s water circulation system.
