## Summary description

Singularity Protium 250mm Acetal reservoir (SC-PROTIUM-L-BA) is a cylindrical liquid-cooling reservoir designed for custom PC water cooling loops. The 250 mm length and Acetal construction provide a robust mounting component for coolant storage and flow management. Suitable for integration with pumps, radiators and fittings in custom loop builds for desktops and workstations.

## Long description

Singularity Protium 250mm Acetal reservoir (SC-PROTIUM-L-BA) is a cylindrical reservoir designed for custom PC liquid cooling loops. Its 250 mm length offers increased coolant capacity and smooth flow characteristics while the acetal (POM) body provides mechanical strength and resistance to common workshop stresses. The reservoir is intended to be integrated with pumps, radiators and standard fittings to act as a coolant storage and distribution point within desktop and workstation cooling systems.
Advantages
The acetal construction ensures dimensional stability and impact resistance compared with some transparent materials, making the reservoir suitable for demanding builds and repeated maintenance. Its extended 250 mm form factor increases coolant volume and simplifies bleed and fill procedures. The cylindrical design supports straightforward mounting options and clean internal flow paths, reducing turbulence and facilitating pump priming when paired with compatible fittings and pump assemblies.
Suitable for (tasks / use cases)
 Custom PC liquid cooling loops for desktops and workstations
 Systems requiring additional coolant capacity or ease of filling/bleeding
 Builds seeking a robust, non-transparent reservoir body for durable installations
 Integration with external or in-chassis pump configurations
Key specifications
 Form factor: cylindrical inline reservoir
 Length: 250 mm
 Material: acetal (POM) body
 Mounting: designed for standard custom loop mounting with threaded ports
 Compatibility: intended for use with standard liquid-cooling fittings, pumps and radiators
How to use
Install the reservoir in the loop according to your system layout, ensuring correct orientation for gravity-assisted fill and bleed operations. Connect inlet and outlet ports to compatible fittings and secure connections to the pump and radiator lines. When filling, use a slow controlled flow to minimise air entrapment; run the pump at low speed initially to assist priming and monitor for leaks. Perform standard leak testing and allow the loop to run until all air is expelled before setting pump speeds to normal operating levels.
Usage recommendations
Use corrosion- and algae-resistant coolant formulations and compatible tubing materials. Periodically inspect seals and fittings for wear, and perform routine maintenance such as coolant replacement and cleaning to preserve performance. If a transparent view of coolant level is required, pair the acetal reservoir with appropriate level indicators or a sight tube in the loop.
