Reservoir for custom water cooling system, Singularity Protium Ausgleichsbehälter 100mm acrylic (SC-PROTIUM-S-SP)

The Singularity Protium Ausgleichsbehälter 100mm acrylic reservoir is a cylindrical vessel built for custom PC water-cooling loops. Designed from clear acrylic, the 100 mm body provides visible coolant capacity and serves as a convenient fill point and bleed chamber. The reservoir is intended for integration with standard fittings and pump/reservoir mounting solutions used in high-performance cooling systems, enabling straightforward filling, air removal and continuous visual coolant monitoring.

Advantages

The acrylic construction offers clear visibility of coolant level and flow while maintaining dimensional stability and compatibility with common cooling system fittings. Its compact 100 mm height balances reservoir capacity with space-efficient installation in varied chassis layouts. The cylindrical shape and smooth bore simplify filling and cleaning operations, and the design supports straightforward integration with pump tops or mounting brackets typical in custom loop assemblies.

Suitable for

• Custom PC water-cooling loops requiring a compact reservoir and fill point
• Enthusiast builds where visual coolant monitoring is desired
• Systems that use separate pump and reservoir mounting solutions
• Test benches and prototype cooling setups for easy filling and bleeding

Key specifications

• Material: clear acrylic
• Shape: cylindrical
• Height: 100 mm
• Function: reservoir, fill point and bleed chamber for liquid cooling
• Compatibility: designed for integration with standard water-cooling fittings and pump/reservoir mounts

How to use

Install the reservoir in a compatible mounting location or secure it to an appropriate pump/reservoir bracket following the mounting hardware instructions. Connect inlet and outlet fittings according to your loop layout, ensuring all threaded connections are sealed with suitable sealing tape or washers. Use the reservoir as the primary fill point: open the fill port to add coolant and run the pump at low speed to circulate liquid while allowing trapped air to escape. Monitor the coolant level visually and top up via the reservoir until the loop is fully purged of air.

Recommendations

For reliable operation, use coolant compatible with acrylic construction and avoid aggressive additives that may cloud or degrade the material. Periodically inspect fittings and seals for leaks, and perform routine coolant changes and reservoir cleaning to prevent contamination. When integrating with pump tops or mounts, verify thread and port compatibility before final assembly.
