Reservoir Singularity Protium 200 mm — acrylic black, for custom water cooling loops

The Singularity Protium 200 mm reservoir is an acrylic, black reservoir designed for custom PC water-cooling loops. At 200 mm length it provides coolant containment, inlet and outlet port integration, and a clean visual profile for desktop systems. The reservoir supports circulation and refill operations while helping separate trapped air from the cooling loop to maintain reliable flow.

Advantages

The acrylic construction offers clear internal visibility where required while the black finish delivers a discrete, uniform appearance inside a case. Its 200 mm size balances capacity and compactness, enabling flexible placement in many standard mid-tower and full-tower layouts. Integrated ports and standard tube connections simplify plumbing and reduce the need for extra adapters, and the design supports efficient coolant flow and air separation for stable temperature regulation.

Suitable for

• Custom PC water-cooling loops in mid-tower and full-tower systems
• Refill and maintenance points for closed custom loops
• Systems requiring a compact yet adequately sized reservoir for coolant volume
• Installations where a black aesthetic and acrylic durability are preferred

Key specifications

• Material: acrylic body
• Color/finish: black
• Length: 200 mm
• Function: coolant reservoir for custom water-cooling loops
• Compatibility: standard tubing and fittings used in PC liquid cooling

How to use

Mount the reservoir securely in a suitable location inside the chassis using the manufacturer-recommended brackets or mounting points. Connect inlet and outlet ports to the loop with compatible tubing and fittings, ensuring all connections are tightened to avoid leaks. Fill the reservoir with the chosen coolant according to the coolant manufacturer’s instructions, then run the pump to circulate fluid and allow trapped air to escape. Monitor the loop for leaks and top up the reservoir as required during the initial bleed and testing phase.

Usage recommendations

Use corrosion-resistant fittings and compatible coolant formulations. Perform initial leak testing outside of critical components where possible, and bleed the loop thoroughly to remove air. Periodically inspect for deposits, discoloration, or fittings loosening and follow coolant manufacturer guidance for replacement intervals.
