Reservoir for liquid cooling Singularity Protium 100 mm acrylic – SC-PROTIUM-S-BF

The Singularity Protium 100 mm acrylic reservoir is a compact expansion tank for PC liquid-cooling loops, designed to provide coolant capacity and a clear visual level indicator. Machined from transparent acrylic with a 100 mm main chamber, this reservoir integrates into custom water-cooling systems to facilitate filling, bleeding air and monitoring coolant level while providing an accessible containment point for potential leaks.

Advantages

The acrylic construction offers good optical clarity for quick visual inspection of coolant level and condition. Its compact 100 mm chamber size balances reservoir capacity with space efficiency in desktop builds. The design supports straightforward integration into existing loops, allowing filling and air removal without extensive disassembly. The clear material and smooth surfaces make routine maintenance and visual leak detection easier than with opaque components.

Suitable for

• Custom PC water-cooling loops in compact and mid-tower systems
• Systems where visual coolant monitoring is required
• Builds that require a small, dedicated filling and bleed point
• Environments where easy inspection for leaks and coolant condition is desired

Key specifications

• Main chamber diameter: 100 mm (round acrylic reservoir)
• Material: clear acrylic (transparent thermoplastic)
• Function: expansion / fill and bleed reservoir for liquid cooling loops
• Mounting: intended for in-case installation within PC water-cooling systems
• Visibility: full external view of coolant level and condition

How to use

Install the reservoir in a suitable location within the case where fittings and tubing can be routed without sharp bends. Connect inlet and outlet ports to the loop according to your system layout, ensuring all fittings are tightened and tubing is properly seated. Fill the loop through the reservoir until the coolant covers the pump inlet and the desired level is reached, then run the pump at low speed to circulate fluid and allow trapped air to rise into the reservoir. Repeat fill and bleed cycles until no significant air remains. During assembly, inspect seals and joints for any signs of leakage and retorque fittings after initial operation.

Usage recommendations

Use coolant formulations and additives that are compatible with acrylic to avoid stress cracking or clouding. Avoid using abrasive cleaners; clean with soft, non-abrasive cloths and manufacturer-recommended solutions. When routing tubing, keep bends gradual and fittings accessible for maintenance. Periodically inspect the reservoir for deposits, discoloration or microcracks and replace if any structural damage is detected.
