Reservoir for custom water cooling Singularity Protium 150 mm acrylic (SC-PROTIUM-150-BF)

The Singularity Protium 150 mm acrylic reservoir is a purpose-designed component for custom PC water-cooling loops. Its 150 mm acrylic tube body provides coolant capacity and a compact mounting form factor that integrates with pumps, radiators and standard fittings used in desktop and workstation liquid-cooling systems. The reservoir supports visible coolant circulation and adds a stable refill and bleed point to an otherwise closed cooling loop.

Advantages

The acrylic construction offers optical clarity for coolant visibility and compatibility with dyed or clear fluids. The cylindrical 150 mm length balances capacity and space efficiency, making it suitable for compact and mid-tower builds. The reservoir is manufactured to fit standard liquid-cooling fittings and mounting options, simplifying installation into custom loops while maintaining reliable fluid containment and flow management.

Suitable for

• Custom desktop PC water-cooling loops
• Workstation liquid cooling installations
• Systems requiring visible coolant reservoirs or fill points
• Builds that need a compact reservoir with standard fitting compatibility

Key specifications

• Material: acrylic reservoir body
• Length: 150 mm cylindrical tube
• Compatibility: standard PC liquid-cooling fittings and pump integration
• Use: passive reservoir for coolant circulation, filling and bleeding
• Form factor: compact, suitable for constrained mounting locations in PC cases

How to use

Mount the reservoir in a secure location inside the case or on a compatible bracket, ensuring it is oriented to allow air to escape to the top fill/bleed point. Connect inlet and outlet ports to the loop using appropriate fittings and tubing rated for PC liquid cooling. After completing leak testing, fill the reservoir with coolant while running the pump intermittently to purge air from the loop. Verify flow and inspect all connections for leaks before normal operation.

Recommendations

Use coolant specifically formulated for PC water-cooling systems and avoid aggressive chemicals that can cloud or damage acrylic. Periodically inspect the reservoir for signs of wear, clouding or deposits and perform maintenance such as coolant replacement and loop flushing according to the coolant manufacturer's guidance.
