A modular reservoir series

The HEATKILLER Tube Series is Watercool's modular system of high end reservoirs, each built around a tube made from borosilicate glass. Modular means that each part can be exchanged separately later on: the D5 bottom of this version, for example, can be swapped for a base that takes a DDC pump. Here is the product information, with the outstanding features Watercool listed.

Three sizes, three versions

To account for the different space availability in current cases, the glass tubes come in 100 mm, 150 mm and 200 mm. That gives a matching tube for every system from mini-ITX to a big tower, and this is the middle size. Besides a standalone version, there are versions with direct connections for pumps. They support D5 pumps by Lowara (formerly known as Laing, now Xylem) and their derivatives, and original DDC pumps, in their own pump chambers. The same D5 version also comes as the shorter HEATKILLER Tube 100 D5 and the taller HEATKILLER Tube 200 D5.

A D5 pump fed straight from the reservoir

On the pump versions, a fitted acetal (POM) part replaces the original tube bottom piece, and the pump is fed directly from the reservoir without any additional parts. This pump adapter comes with a streaming-optimized pump chamber whose flow-optimized channels give less flow restriction and a lower noise level. It causes fewer vortices during use, which has a positive effect on both the flow rate and air bleeding.

Anti-cyclone effect

Popular high-power pumps such as the D5 and DDC often form a vortex in the suction area of the fluid and suck in air. That reduces the cooling performance and carries air bubbles into the loop. The exclusively developed anti-cyclone inlay, located at the bottom of the reservoir, prevents the vortices that easily form there. Watercool says it completely prevents this from happening, which reduces noise levels and makes air bleeding easier.

Borosilicate glass tube

Borosilicate is a glass with very high chemical and thermic resistance. It is scratch-resistant and shows very low heat expansion, almost none in Watercool's words. Watercool calls these outstanding features an ideal material for reservoirs.

Large filling mouth and large volume

Thanks to a large filling mouth with a bayonet catch lid, the reservoir can be opened without any tools and is easy to fill. The lid opens with a quarter turn counterclockwise, and Watercool says it has never been easier to re-fill a cooling medium. In designing the series, Watercool took great care not to waste any of the available volume. Because they need fewer re-fills, they are very low maintenance.

Made in Germany

Watercool states that the Tube Series reservoirs are completely produced in Germany on its own CNC machines in Waren, each one finished under the dual control principle.

What the loop needs

Two G1/4 ports take two fittings for your tube size. A bare D5 pump motor needs no preparation. If you own a LAING/LOWARA D5 with its original cover, remove that cover first: turn the large ring left to detach the pump motor.

Extensive optional accessories

The series has various optional features, sold separately. For an optimal integration into a water cooled system, we offer Watercool's variable mounting systems to fit your build:

• Horizontal mount (pedestal): two different height pedestals, the short stand and the long stand, attach the reservoir to the case floor or let it stand free-standing. A decoupling kit for the stand is available.
• Vertical mount: the multifunctional bracket mount of the Basic Mounting Kit offers options for mounting on a flat surface such as the case wall. Several adapters have been made for it.
• Some adapters attach the reservoir to 120x120mm or 140x140mm cooler slots (fan mounts): the 120 mm fan adapter pair and the 140 mm fan adapter pair.
• Others allow mounting the reservoir on a radiator from the MO-RA3 series. For the MO-RA IV there is the MO-RA IV Heatkiller Tube Adapter.
• Illumination: the reservoir can be set in scene with splash-safe LED strips in various colors, RGB or aRGB, hidden in the struts of the reservoir cage. See reservoir lighting.
• Colored struts: to customize the reservoir you can exchange the default black struts. Watercool offers aluminum struts in natural color, which third parties can anodize in any color, or with a choice of anodized colors (blue or red).

Technical data

Notes

• When installing or removing the D5 pump, take care not to squeeze or otherwise damage its cable.
• To fit the pump, take the D5 lock ring off the bottom (M4x12 screws), turn the empty reservoir upside down and put the O-ring in place. Guide the pump cable through the lock ring before the pump goes on, then tighten the M4x12 screws evenly across. A spare O-ring for the D5 pump is available.
• Check all seals before the first start-up; with squeezed or damaged O-rings the reservoir must not be used.
• The glass tubes use O-rings of 4 mm or 5 mm to make up for length tolerance. Reuse the same strength you found in your reservoir. Watercool's replacement kit contains both strengths, and the O-rings for the glass tube are in stock as a spare part.
• Drain the reservoir and take it out of the loop completely before you alter it.
