The Alphacool Eisbecher Helix 250 is an optical highlight of the Eisbecher family. The helix inside the reservoir creates a special effect reminiscent of a DNA strand, making it a true eye-catcher. In the center of the reservoir, there is a UV cathode tube powered by a 3-pin connector. When using UV-reactive water, a strong glow emanates from within the container, creating a truly impressive effect.

The bottom and the lid are made entirely of acetal but are covered by aluminum caps for a premium look. The aluminum caps do not come into contact with the water. The connection options are extensive, with three G1/4" threads located in both the lid and the bottom. Additionally, there are two more G1/4" connection options on the side of the bottom, providing various mounting positions.

Two different mounting sets are included. One set features the aluminum brackets known from the Eisbecher series, which fit flush with the top and bottom of the Helix and allow for mounting the reservoir on a radiator. This requires a 240 mm or 280 mm radiator, or a larger counterpart such as a 360 mm or 420 mm radiator. Alternatively, clip mounts are included, which can be attached to the case with a screw. The Eisbecher Helix simply clips in place, offering flexible mounting options.
