## Long description

The Watercool Heatkiller Watercool 0.5L Black Transparent 70x70x248.5mm is a compact modular reservoir designed for closed-loop and custom liquid cooling systems. With a 0.5-litre coolant capacity and dimensions of 70 × 70 × 248.5 mm, this Heatkiller Tube Series model combines a borosilicate glass tube and a bayonet catch lid for easy filling and long-term chemical and thermal resistance. The reservoir is engineered to reduce maintenance frequency through an efficient internal layout and to simplify pump integration through dedicated pump adapter options.
Advantages
The borosilicate glass tube provides high scratch resistance, low thermal expansion and excellent chemical resistance, contributing to reliable long-term operation. A large filling mouth with a bayonet catch lid enables tool-free opening and easy refills. The reservoir includes an anti-cyclone inlay to prevent vortex formation and simplify air bleeding while lowering noise. Streaming-optimized pump chambers and available pump adapters improve flow stability and compatibility with common D5 and DDC-style pumps. The product is manufactured in Germany and designed for minimal wasted volume to reduce refill frequency.
Suitable for
Custom PC liquid cooling loops with limited installation space
Small server or workstation cooling setups requiring a compact reservoir
Systems using D5 or DDC-compatible pump adapters
Enthusiasts seeking a transparent reservoir with easy filling and maintenance

How to use
Mount the reservoir securely using an appropriate mounting kit or bracket compatible with your case layout. If using a pump-adapter version, attach the selected pump (D5 or DDC-style) according to the adapter instructions, ensuring correct sealing of all fittings. Fill the reservoir through the large filling mouth until the recommended coolant level is reached, then close the bayonet catch lid. Prime the pump following the pump manufacturer’s procedure and run the loop at low speed initially to remove trapped air; monitor coolant level and system temperatures during initial operation.
Usage recommendations
Use only compatible coolants and follow the coolant manufacturer's instructions. Regularly inspect seals, fittings and the reservoir tube for deposits or wear. When installing in restricted spaces, verify clearance for the total reservoir height (248.5 mm) and ensure adequate ventilation around the pump and radiators. Consider available accessories such as mounting brackets, pedestals and LED illumination strips for easier integration and improved system maintenance.
