Watercool HEATKILLER® Tube 100 BASIC Reservoir, G1/4, 100mm, Borosilicate Glass, Clear (30198)

A standalone tube reservoir with a 100 mm borosilicate glass tube, about 250 ml capacity and two G1/4 ports, with no pump fitted. The Watercool HEATKILLER® Tube 100 BASIC has a POM cover and bottom, bare aluminum struts and a large filling mouth with a tool-free bayonet lid.

• Pump: None (standalone bottom)
• Length and capacity: 100 mm tube, 65 mm diameter, approx. 250 ml
• Ports: 2x G1/4
• Size: 70 x 70 x 146 mm

The HEATKILLER® Tube Series

The Tube Series is Watercool's modular system of high end reservoirs built around a glass tube made from borosilicate glass. Modular means every part can be exchanged on its own later, so the standalone base of this reservoir can be swapped for a D5 or DDC bottom. Watercool describes the BASIC as a high-end expansion tank in its typical design, made from borosilicate glass, aluminum and acetal. It says the series has some outstanding features; they are listed here, one by one.

Large filling mouth and bayonet lid

Thanks to the large filling mouth and 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. Watercool says it has never been easier to re-fill a cooling medium.

Borosilicate glass tube

Borosilicate is a glass with a very high chemical and thermic (thermal) resistance. It is scratch-resistant and has very low heat expansion. Watercool calls it the ideal material for reservoirs because of these features.

Three sizes and three versions

To account for the different space availability in current cases, the glass tubes come in sizes 100 mm, 150 mm and 200 mm, from mini-ITX to big tower. Besides a standalone version like this one, there are versions with direct connections for pumps. They support D5 and DDC pumps by Lowara (formerly known as Laing) and their derivatives. In those versions an acetal (POM) part replaces the bottom piece, and the pump is fed straight from the reservoir.

The same 100 mm reservoir with black anodized struts is the Tube 100, and with a pump bottom it is the Tube 100 D5. The longer BASIC is the Tube 150 BASIC.

Large volume

In designing the series, Watercool took great care not to waste any of the available volume. That makes the reservoirs very low maintenance, because they need fewer re-fills.

What the loop needs

The reservoir has two G1/4 connection threads, so it takes two fittings, and a separate pump.

Notes

• Watercool's most important information: check all seals before the first start-up; a reservoir with squeezed or damaged O-rings must not be used.
• Drain the reservoir and take it out of the loop before any alteration.
• The glass tubes are sealed with O-rings of 4 mm or 5 mm strength to compensate length tolerance; use the same strength you found in your reservoir. Watercool's replacement kit, the O-rings for the glass tube, contains both strengths.
