Reservoir (Ausgleichsbehälter) BitsPower Premium Cuboid 150 mm Acrylic - BPPRE-WTCR150

BitsPower Premium Cuboid 150 mm acrylic reservoir (Reservoir Ausgleichsbehälter) is a compact liquid cooling reservoir for custom PC water-cooling loops. The 150 mm cuboid form provides coolant storage, visible coolant level and flow observation through clear acrylic material. Designed to connect with standard G1/4" fittings and tubing, this reservoir integrates with pumps, radiators and water blocks to maintain coolant volume and simplify filling and bleeding during system assembly and maintenance.

Advantages

The acrylic construction offers clear visibility of coolant color and flow while maintaining structural rigidity. Its cuboid 150 mm profile saves space in chassis layouts where vertical cylindrical reservoirs are impractical. The reservoir includes multiple threaded ports for inlet, outlet and drain connections, enabling flexible loop routing and straightforward integration with common fittings and tubing types. The transparent design aids in leak inspection and coolant level monitoring without disassembly.

Suitable for

• Custom PC water-cooling loops in mid-tower and full-tower cases
• Systems requiring visible coolant level and simple fill/bleed points
• Compact layouts where a low-profile cuboid reservoir fits better than tall cylindrical reservoirs
• DIY builds that use standard fittings and tubing for easy integration

Key specifications

• Material: Clear acrylic reservoir body
• Form factor: Cuboid, 150 mm height
• Connection type: Standard threaded coolant ports suitable for common water-cooling fittings
• Compatibility: Designed for integration with pumps, radiators and water blocks in custom loops
• Function: Coolant storage, visual monitoring of level and flow, fill and drain capability

How to use

Mount the reservoir in a suitable position within the chassis where the 150 mm cuboid profile fits and allows access to threaded ports. Connect inlet and outlet ports to the loop using compatible fittings and tubing, ensuring secure, leak-free connections. When filling, use the top fill port and monitor the visible coolant level through the acrylic body; bleed trapped air by opening bleed/drain ports as needed. Securely fasten the reservoir and recheck all connections before powering the pump and running the loop.

Recommendations

Use only coolant formulations compatible with acrylic and with recommended corrosion inhibitors or biocides. Periodically inspect the reservoir for signs of discoloration, deposits or micro-leaks and perform coolant replacement according to system maintenance intervals. Avoid exposure to strong solvents or abrasive cleaners that can damage acrylic surfaces.
