## Summary description

Singularity Protium Ausgleichsbehälter is a 250 mm acrylic reservoir designed for liquid-cooling loops in desktop PCs. The cylindrical reservoir provides coolant storage and flow integration for custom water-cooling systems. Made of clear acrylic, it fits setups that require a long 250 mm capacity reservoir and connects to standard coolant tubing and fittings for efficient system filling and bleed.

## Long description

Singularity Protium Ausgleichsbehälter is a 250 mm acrylic reservoir engineered for custom liquid-cooling loops in desktop PCs. The clear cylindrical body provides visible coolant capacity and integrates into loop topologies as a reservoir and fill point. Made from transparent acrylic, the 250 mm length gives extended coolant volume while maintaining a slim profile for installations where a longer reservoir is required. The reservoir is compatible with common fittings and standard coolant tubing, allowing straightforward integration into existing water-cooling systems.
Advantages
The acrylic construction offers optical clarity for monitoring coolant level and condition. Its 250 mm length increases system coolant volume, which can improve thermal stability in larger loops. The cylindrical shape and clear finish enable easy visual inspection and an unobstructed view of flow and coolant colour. The reservoir connects to standard tubing and fittings for reliable mechanical and hydraulic integration without needing proprietary adapters.
Suitable for
 Custom desktop PC liquid-cooling loops that require additional coolant capacity
 Builds where visual monitoring of coolant level and colour is desirable
 Systems that use standard compression, barbed, or G1/4 fittings and common tubing sizes
 Enclosures or mounting arrangements that can accommodate a 250 mm cylindrical reservoir
Key specifications
 Material: clear acrylic (transparent)
 Length: 250 mm cylindrical body
 Function: coolant reservoir and fill/bleed point for liquid-cooling loops
 Compatibility: designed to connect with standard coolant tubing and fittings used in PC water-cooling
 Finish: polished clear surface for visual coolant inspection
How to use
Mount the reservoir in a suitable location inside the chassis or external bracket that accepts a 250 mm cylinder, ensuring secure fastening to avoid movement. Install compatible fittings into the reservoir ports and connect to the loop using tubing sized to match your fittings. When filling, use the reservoir as the fill and bleed point: slowly add coolant while operating the pump at low speed to purge air, top up until the loop is fully filled and free of bubbles, then secure the fill port. Regularly inspect the clear acrylic body for level and clarity, and perform routine coolant maintenance according to your coolant manufacturer’s guidance.
Usage recommendations
Place the reservoir so its fill port is accessible for maintenance and choose fittings that match your tubing diameter to ensure leak-free connections. Avoid exposure to strong solvents or abrasive cleaners that can scratch or haze the acrylic surface; use mild soap and water for external cleaning. When assembling, verify that clamps or compression rings are properly tightened and that the loop is pressure-tested before prolonged operation.
