Depósito de compensación para bombas D5 Aqua-Computer ULTITUBE D5 100 (modelo 34092) para sistemas de refrigeración líquida

The Aqua-Computer ULTITUBE D5 100 reservoir is designed for integration with D5-series pumps in PC water cooling systems. It functions as an expansion and collection reservoir, providing coolant storage and aiding in air separation to stabilise flow and simplify refilling. Constructed for compatibility with standard D5 pump mounts, this model suits custom liquid-cooling builds where a compact, pump-compatible reservoir is required.

Advantages

The ULTITUBE D5 100 offers a compact form factor that mounts directly with D5 pumps, reducing installation complexity in tight cases. Its transparent tube design enables quick visual inspection of coolant level and condition. By acting as an air separation point and buffer, the reservoir helps maintain steady pump operation and reduces the frequency of manual top-ups during routine maintenance.

Suitable for

• Custom PC water cooling loops using D5-series pumps
• Systems requiring a compact pump-compatible reservoir for limited space enclosures
• Builds where easy coolant monitoring and periodic refilling are needed
• Maintenance tasks that require an accessible collection/expansion point

When it may not be suitable

The ULTITUBE D5 100 is not intended for pump types other than the D5 series or for systems that require very large coolant capacity; users with high-capacity loops may prefer larger reservoirs. It is also not a standalone filling station—installation with an appropriate D5-compatible pump and fittings is necessary for correct operation.

Key specifications

• Reservoir type: tube-style expansion/collection reservoir
• Compatibility: designed for D5-series pump mounting
• Material: transparent tube body for visual coolant monitoring
• Capacity: small/compact capacity appropriate for minor buffering and air separation (model size: 100)
• Intended use: PC water cooling loops and custom liquid-cooling systems

How to use

Mount the ULTITUBE D5 100 to a D5-compatible pump or bracket following the pump manufacturer’s mounting instructions. Connect inlet and outlet fittings according to your loop layout, ensuring all seals and clamps are secure. Fill the loop with appropriate coolant, use the reservoir as the top-up point, and bleed air by running the pump at low speed or following standard loop-bleeding procedures. Regularly inspect the transparent tube to monitor coolant level and presence of air bubbles.

What to consider before purchase

• Confirm compatibility with your D5 pump model and available mounting points in your case
• Ensure the reservoir capacity and physical dimensions fit your planned loop and case layout
• Plan for compatible fittings, tubing diameter, and sealing components required for installation
• Consider whether a larger reservoir is necessary for your system’s coolant volume and maintenance preferences

Recommendations

Use corrosion- and algae-resistant coolant formulated for PC water cooling, and perform periodic visual checks of the ULTITUBE D5 100 for level and clarity. During initial filling and bleeding, operate the pump at reduced speed to minimise aeration and ensure trapped air migrates to the reservoir for removal.
