Aqua Computer aqualis DDC 100 ml

The aqualis DDC 100 ml is a precision‑engineered cooling system expansion tank designed for high‑performance liquid cooling setups. It serves as the critical component that maintains optimal coolant volume, pressure stability, and thermal equilibrium across a PC’s water loop.

Key Functionalities

1. Pressure Regulation: The tank incorporates an internal pressure‑release valve calibrated to 2 bar (29 psi). This ensures that the system never exceeds safe operating pressure, protecting pumps, fittings, and radiators from damage.

2. Volume Compensation: With a nominal capacity of 100 ml, the tank absorbs expansion caused by temperature fluctuations. When coolant heats up, it expands; the tank’s flexible bladder accommodates this volume change, preventing over‑pressure conditions.

3. Air Venting: A dedicated air vent port allows trapped air to escape during system fill or maintenance. This feature prevents air pockets that could reduce cooling efficiency or cause pump cavitation.

Design & Build Quality

The tank is constructed from high‑grade, polypropylene (PP) material, chosen for its chemical resistance to common coolant formulations and its durability under thermal cycling. The outer shell features a matte finish that resists fingerprints and corrosion.

Threading: All connections use the standard G1/4” NPT thread size (62 mm nominal), compatible with most commercial fittings, adapters, and manifolds. This universality simplifies integration into existing loops without requiring custom adapters.

The tank’s dimensions are compact: 132 mm in length, 62 mm in diameter, and a wall thickness of 2–3 mm. Its lightweight design (approximately 200 g) makes it easy to mount on a case or radiator bracket without adding significant weight.

Installation Guidelines

1. Positioning: Mount the tank horizontally or vertically, ensuring that the vent port faces upward. This orientation allows air to rise and escape efficiently.
2. Connection: Attach the inlet and outlet fittings using standard G1/4” NPT threads. Tighten securely but avoid overtightening to prevent thread damage.
3. Filling Procedure: Fill the system with coolant while monitoring pressure gauges. Once the tank is full, close the vent valve to lock in the correct volume.
4. Testing: Run the loop for at least 30 minutes before powering on the PC. Verify that pressure remains stable and no leaks are present.

Compatibility & Ecosystem

The aqualis DDC 100 ml is part of Aqua Computer’s broader line of cooling accessories, including radiators, pumps, and fittings. It pairs seamlessly with:

• Aqua Computer iCooler pump series.
• Aqua Computer iRadiator models.
• Standard G1/4” manifold kits from third‑party manufacturers.

Its universal threading and compact size make it a drop‑in replacement for older expansion tanks or an upgrade for new builds seeking reliable pressure management.

Maintenance & Longevity

The tank’s polypropylene construction resists corrosion, algae growth, and mineral deposits. However, periodic inspection is recommended:

• Check the vent valve for blockage or leakage.
• Inspect threads for wear or damage.
• Replace the tank if any cracks or deformities appear, as these can compromise pressure integrity.

With proper care, the aqualis DDC 100 ml can operate reliably for many years in a well‑maintained cooling loop.
