Barrow Ausgleichsbehälter 164mm DDC Acryl – white, 164 mm reservoir for DDC pump mounting (PBTT-BBB3180)

Barrow Ausgleichsbehälter 164mm DDC Acryl – white is a 164 mm acrylic reservoir engineered for integration with DDC-series pump assemblies in custom PC liquid-cooling loops. The white acrylic housing creates a visible coolant chamber while maintaining a compact vertical footprint compatible with common DDC pump mounting patterns. Designed for systems that require a dedicated reservoir directly above or alongside a DDC pump, it supports routine filling, bleeding and coolant level monitoring without adding significant bulk to the cooling loop.

Advantages

The acrylic construction offers clear visual access to coolant level and flow while the 164 mm length provides a compact volume adequate for small to medium custom loops. The reservoir’s interface matches DDC pump form factors to simplify mounting and reduce the need for custom brackets. White finish provides neutral aesthetic compatibility with a wide range of builds and makes coolant colour more visible. The design facilitates bleed procedures and air separation when combined with DDC pumps.

Suitable for

• Custom PC liquid-cooling loops using DDC-series pumps
• Compact or vertical reservoir installations where space is limited
• Systems requiring visible coolant monitoring and easy filling/bleeding

Key specifications

• Material: acrylic reservoir body
• Length/height: 164 mm
• Colour/finish: white translucent housing for coolant visibility
• Compatibility: designed for mounting with DDC-series pump form factors
• Mounting orientation: vertical reservoir configuration for DDC pumps

How to use

Mount the reservoir directly to the DDC pump or to a bracket designed for DDC pump and reservoir assemblies, ensuring secure mechanical attachment and proper shaft alignment. Connect inlet and outlet tubing according to the cooling loop layout and verify that fittings are tight. When filling, introduce coolant slowly to allow trapped air to escape; perform several fill-and-run cycles at low pump speed to purge microbubbles. Monitor coolant level and top up as needed before sealing the loop.

Recommendations

Use coolant additives and corrosion inhibitors recommended for acrylic components, avoid aggressive solvents or cleaners that can cause crazing, and check compatibility of tubing and fittings materials to maintain leak-free connections. For reliable air separation, operate the pump at reduced speed during initial bleeding and allow the system to run briefly to stabilise flow before final tightening and sealing.
