Reservoir for custom water cooling, Singularity Protium 200mm Acetal – SC-PROTIUM-M-BA

The Singularity Protium 200mm Acetal reservoir is a vertical reservoir designed for custom PC water cooling loops. Constructed from acetal engineering thermoplastic, this 200 mm reservoir provides a compact, durable solution for holding coolant, simplifying filling and bleeding procedures, and integrating with pumps, radiators and fittings in a custom loop. Its opaque acetal body offers chemical resistance and rigidity suited to repeated use in system builds and maintenance.

Advantages

The acetal construction delivers strong mechanical stability and resistance to many common coolants and additives, reducing the chance of deformation or stress over time. The 200 mm vertical format balances capacity and space efficiency, allowing straightforward installation in cases or enclosures with limited depth. Designed for compatibility with standard fittings and pump setups, the reservoir streamlines loop assembly and routine maintenance operations such as draining, refilling and air bleeding.

Suitable for

• Custom PC water cooling loops in compact or mid-size builds
• Systems requiring a durable, opaque reservoir material
• Builders who need simplified filling and bleeding access
• Maintenance-oriented setups where long-term chemical resistance is preferred

Key specifications

• Orientation: vertical, 200 mm usable height
• Material: acetal (opaque engineering thermoplastic)
• Function: coolant reservoir for closed-loop custom water cooling
• Integration: compatible with standard pump and fitting interfaces used in custom loops
• Application: designed for mounting inside PC cases or dedicated loop chambers with limited depth

How to use

Install the reservoir in a secure vertical position that provides adequate clearance for fittings and tubing. Connect inlet and outlet ports to the loop using compatible fittings and tubing, and ensure pump orientation and flow direction match the loop design. When filling, add coolant slowly while running the pump at low speed and perform air bleeding by tilting or briefly raising loop sections as needed. Follow standard safety precautions for handling coolants and ensure all fittings are tightened to prevent leaks before putting the system under full operation.

Usage recommendations

Use coolant and additives that are chemically compatible with acetal materials; maintain regular inspection intervals for fittings and seals. When performing maintenance, drain and flush the loop periodically according to coolant manufacturer guidance to avoid buildup and preserve component longevity.
