The Alphacool Helix Eisbecher captivates with its unique Helix Optic, including elegant aluminium caps for its upper and bottom sides. The 60mm diameter version also offers a UV cathode tube to illuminate UV-reactive water from within.  Highlights Helix Optic Four colour combinations Two diameter sizes – 50mm and 60mm 60mm version comes with UV cathode tube The Alphacool Eisbecher Helix 250 is the optical highlight of the Eisbecher family. The helix inside the reservoir gives off a unique effect reminiscent of a strand of DNA, making it a real eye-catcher. In the middle of the reservoir is a UV cathode tube powered over a 4-pin plug. If UV-reactive water is used, the cathode tube will create a strong glow from the inside of the reservoir, making for a unique effect that really impresses.  The base and top are made entirely of acetal, but are covered with aluminium caps for an elegant look. The aluminium caps do not come in contact with the water, of course. The installation options are considerable, with three G1/4 threads in both the bottom and top. The bottom also has two extra G1/4 connection points. This gives you lots of options for positioning your reservoir.  You’ll also receive two different installation sets. One of them is well-known from the Eisbecher series – the aluminium brackets that lock flush with the top and bottom of the Eisbecher and provide the option of mounting on a radiator. This requires a 240 or 280mm radiator or a larger equivalent, such as a 360 or 420mm. The alternative installation set is a clip bracket, made up of two clips which are fastened to the case with one screw each. The Eisbecher Helix just needs to be clipped on, giving you lots of flexibility in how you mount it.  The Eisbecher Helix is available in multiple colour combinations. The cap, bottom, and the helix itself can all be different colours.
