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 DDC bottom of this version, for example, can be swapped for a base that takes a D5 pump. The outstanding features Watercool listed for the series are described here, with the product information for this size.

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 short one. Besides a standalone version, there are versions with direct connections for pumps. They support the D5 and DDC pumps by Lowara (formerly known as Laing, now Xylem) in their own pump chambers. If you need more room, the same version comes as the HEATKILLER Tube 150 DDC.

A DDC 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. That keeps these reservoirs very low maintenance, because they need fewer re-fills.

Made in Germany

Watercool states that the Tube Series reservoirs are completely produced in Germany, on its own CNC machines in Waren, with many steps done by hand and each product finished under the dual control principle.

What the loop needs

Two G1/4 ports take two fittings for your tube size. The motor of an original DDC pump goes into the bottom: remove the pump body with its four torx screws, and only the pump motor (rotor and stator) is used from then on.

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 such as red and blue.

Technical data

Notes

• When installing or removing the DDC pump, take care not to squeeze or otherwise damage its cable; it leaves through the small lateral notch in the pump cover. Put the O-ring back in its intended position before the cover goes on.
• The bottom is held by four M4x35 DIN956 screws; lay the empty reservoir on its side to reach them.
• 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.
