Reservoir Aqua-Computer aqualis XT — Black/Transparent, 0.15 L, 50×50×189 mm

The Aqua-Computer aqualis XT reservoir in Black/Transparent is a compact, low-volume reservoir designed for PC liquid-cooling loops. With a capacity of 0.15 liters and external dimensions of 50 × 50 × 189 mm (W×D×H), it is intended for small form-factor builds or custom cooling systems that require a minimal footprint while still allowing visual monitoring of coolant level through its transparent window.

Advantages

This reservoir combines a small physical size with a clear viewing area for easy inspection of coolant level and flow. Its construction is suitable for integration into tight spaces and custom mounting arrangements. The low internal volume supports reduced total coolant requirements and faster bleed or refill cycles compared with larger reservoirs.

Suitable for

• Small form-factor PC builds with limited internal space
• Custom or experimental water-cooling loops with low coolant volume
• Systems where visual coolant level monitoring is required
• Compact test rigs and bench setups

Key specifications

• Capacity: 0.15 liters
• External dimensions: 50 × 50 × 189 mm (W × D × H)
• Finish: black housing with transparent viewing area
• Orientation: vertical-mounted reservoir design
• Compatibility: for use in PC liquid-cooling loops with standard fittings (verify fitting sizes separately)

How to use

Install the reservoir into the cooling loop according to the system layout, ensuring secure mounting and proper orientation for filling and air extraction. Connect inlet and outlet fittings compatible with your tubing and pump configuration and use recommended coolant for your loop. During initial setup, fill the reservoir slowly and cycle the pump intermittently to purge trapped air; monitor the transparent section to confirm coolant level and absence of air bubbles.

Usage recommendations

Use the reservoir in systems where low coolant volume and compact dimensions are priorities. Check compatibility of fittings and mounting points before installation, and perform leak testing after connecting the loop. Regularly inspect the transparent area for coolant clarity and level, and top up or flush the loop as part of routine maintenance.
