watercool heatkiller tube reservoir, 150mm

A standalone 150 mm glass tube reservoir, with no pump seat. The Watercool HEATKILLER® Tube 150 holds about 375 ml in a borosilicate glass tube, with a large filling mouth on top, black anodized struts and two G1/4 ports.

A modular reservoir series

The HEATKILLER Tube Series is Watercool's modular system of high end reservoirs, all built around a tube made from borosilicate glass. Each part can be exchanged separately later on, so the bottom of a reservoir can be changed when the loop changes. Watercool listed some outstanding features for the series, and they are described here.

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 this 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. On those, the pump adapter comes with streaming-optimized pump chambers. Each chamber causes fewer vortices during use, which has a positive effect on both flow rate and air bleeding. With a pump, the same size comes as the HEATKILLER Tube 150 D5 and the HEATKILLER Tube 150 DDC. The BASIC version of this reservoir has bare aluminum struts.

Anti-cyclone effect

The exclusively developed anti-cyclone inlay, located at the bottom of the reservoir, prevents the vortices that easily form in reservoirs. 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 puts air bubbles into the loop. Watercool says its inlay completely prevents this. It also reduces noise levels and makes air bleeding easier.

What the loop needs

Two G1/4 ports take two fittings for your tube size. This version holds no pump, so the loop needs a pump with its own top.

Technical data

Notes

• 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, for example to change the struts or fit an LED strip.
