Reservoir for Water Cooling Singularity Protium Ausgleichsbehälter 200mm – Acetal

Singularity Protium Ausgleichsbehälter 200mm in acetal is a cylindrical reservoir designed for custom PC water cooling loops. At 200 mm length it provides additional coolant capacity and an accessible fill/air-bleed point for loop maintenance. Machined from acetal, the tube and end caps offer chemical resistance and predictable thermal behaviour in closed-loop cooling systems, and the reservoir is intended to integrate with common pump tops, fittings and tubing used in enthusiast builds.

Advantages

The acetal construction provides good resistance to many common coolant additives and solvents while maintaining dimensional stability. Its cylindrical 200 mm form factor increases loop volume and improves air separation compared with smaller integrated reservoirs. The design accommodates standard liquid-cooling fittings and mounting options so it can be combined with a variety of pumps and radiators. The reservoir also enables easier filling and bleeding of trapped air during installation and maintenance.

Suitable for

• Custom PC liquid cooling loops for desktops and workstations
• Enthusiast builds needing increased coolant volume or improved air separation
• Upgrading or replacing an existing reservoir in a modular loop
• Systems that use acetal-compatible coolants and additives

Key specifications

• Material: acetal (plastic engineering grade)
• Form factor: cylindrical reservoir, 200 mm length
• Function: coolant storage, fill and air-bleed point for loop stability
• Compatibility: designed to mate with common liquid-cooling pump tops, standard fittings and soft/hard tubing
• Intended use environment: sealed PC water-cooling loops

How to use

Install the reservoir in your loop following standard liquid-cooling layout practices, ensuring the reservoir sits at an appropriate high point or return location to aid air separation. Use compatible fittings and tubing, secure all connections and mount the reservoir to a stable chassis location or pump bracket. When filling, introduce coolant slowly and run the pump at low speed to purge air; top up through the reservoir and repeat bleed cycles until no air bubbles are present. Verify all seals and recheck for leaks after initial operation.

Usage recommendations

Use coolants and additives that are compatible with acetal materials, avoid prolonged contact with aggressive solvents, and perform regular visual inspections. If combining with acrylic or glass components, ensure appropriate mounting and clearance to prevent mechanical stress. During maintenance, drain and clean the reservoir following the coolant manufacturer's instructions.
