Reservoir Singularity Protium Ausgleichsbehälter 100 mm acrylic for custom water cooling loops

Singularity Protium Ausgleichsbehälter 100 mm is an acrylic cylindrical reservoir designed for custom PC water cooling loops. The 100 mm tall reservoir provides coolant storage, a convenient fill point and improves loop maintenance by allowing easy bleeding and visual monitoring of fluid level. Constructed from clear acrylic, the reservoir integrates with standard fittings and mounting options used in custom liquid-cooling assemblies and is intended for system builders and enthusiasts assembling or upgrading cooling loops.

Advantages

The acrylic construction offers clear visual monitoring of coolant color and level while remaining lightweight and corrosion-resistant. Its compact 100 mm size makes it suitable for many case layouts without occupying excessive space. The cylindrical form factor simplifies routing and mounting in vertical or horizontal orientations and supports standard threaded fittings for leak-resistant connections. Designed for compatibility with common loop components, the reservoir facilitates routine maintenance such as refilling and bleeding.

Suitable for

• Custom PC water cooling loops in desktop and compact cases
• System builds requiring a compact cylindrical reservoir for coolant storage
• Enthusiast upgrades where visual monitoring of fluid level and color is needed

Key specifications

• Material: clear acrylic cylinder
• Height: 100 mm (cylindrical reservoir length)
• Form factor: cylindrical
• Connection: compatible with standard threaded liquid-cooling fittings
• Function: coolant storage, fill and bleed point for loop maintenance

How to use

Install the reservoir in a suitable location within the case where the height and orientation fit the available space. Connect inlet and outlet ports using appropriate threaded fittings and tubing sized to match the rest of the loop. Fill the reservoir with compatible coolant, then use the reservoir as the primary fill and bleed point during initial loop filling and periodic maintenance. Ensure all fittings are tightened to manufacturer torque recommendations and perform leak testing before powering the system.

Usage recommendations

Use coolant fluids specified for PC liquid-cooling systems to avoid polymer degradation and staining. Mount the reservoir to minimize stress on fittings and tubing, and retain easy access for refilling and bleeding. Inspect seals and connections periodically and replace any worn O-rings to maintain leak-free operation.
