Aquacomputer LEAKSHIELD Leakage Protection System for ULTITUBE (34137)

The Aquacomputer LEAKSHIELD Leakage Protection System for ULTITUBE (34137) is a negative pressure leak prevention unit that replaces the top lid of an ULTITUBE series reservoir. It holds the loop at up to 450 mbar of vacuum with an integrated vacuum pump, connects over internal USB, and the ULTITUBE reservoir it needs is not included.

Properties

• For: ULTITUBE series reservoirs, mounted upright
• Negative pressure: max. -450 mbar
• Display: 128 x 64 pixels OLED, rotates 360°
• Interface: internal USB 2.0, 5 V DC, max. 500 mA
• Size: approx. 72 x 77 x 29 mm, 140 g

Leak prevention

Thanks to its negative pressure, the LEAKSHIELD actively protects against leaks across the whole coolant loop. If a leak opens, ambient air enters instead, which means no more coolant leaks out of the system. The air that gets in is then pumped out of the system by the integrated vacuum pump, which keeps the negative pressure up. Of course, it does not protect against major damage, such as torn tubes: with a massive leak, for example a completely separated tube, coolant may still exit. Aquacomputer's claim is that the user almost no longer needs to worry about the tightness of the water cooling system. To make sure there is negative pressure everywhere in the loop, the amount can be adjusted to suit the installed coolant pump.

What the loop needs

A reservoir of the ULTITUBE series, such as the ULTITUBE D5 150 reservoir, is required and not included. To install, hold the glass tube, unscrew the top lid anti-clockwise and screw the LEAKSHIELD on in its place. The reservoir must be mounted upright/vertically, because operation is not possible with it installed horizontally. ULTITUBE 50 reservoirs should not be used, as their coolant capacity is insufficient; at least 100 ml of air in the reservoir is needed for safe operation.

All components in the cooling system must be qualified for the configured negative pressure permanently. Parts from suppliers other than Aquacomputer must be checked before starting operation. Especially soft, thin walled tubes are not suitable. As a broad rule, the outer diameter of PVC tubing should be at least 1.5 times its inner diameter, while for PUR tubing a factor of 1.2 is usually sufficient. Hardtubes are generally suitable. Aquacomputer approves coolants of its Double Protect Ultra (DP Ultra) series. For systems with more than one pump, Aquacomputer says to check the total pump pressure, for example by measuring it.

For aqualis, aquatube or aquainlet reservoirs, Aquacomputer offers an adapter version, LEAKSHIELD UNIVERSAL.

Notes

• Never touch the membrane on the bottom side of the LEAKSHIELD: a damaged membrane lets moisture in and can make the unit fail. A replacement membrane (34158) is available.
• Under no circumstances use coolants with flammable substances. Coolants with particles can clog or even destroy the membrane.
• To keep the unit running while the PC is in standby, set the USB port in the BIOS so its power supply stays on, or use an external USB power supply.
• Turn off the power supply completely, or unplug the mains cord, before connecting or disconnecting any cable. Check that the USB pin alignment matches the motherboard header.
