Screw-to-connect couplings for liquid cooling CDUs
)
With its larger inner diameter, ultraFLOW is ideal for the cooling distribution unit (CDU) in the liquid cooling system. High flow and low pressure drop are significant features of the ultraFLOW family of quick couplings, enabling new design opportunities to save energy and lower investment costs.
The ultraFLOW STC screw-to-connect couplings offer large-diameter versions of the spill-free ultraFLOW series. As the larger diameter and higher flow rate increase the required connection force, the STC version is a screw-to-connect type to overcome this and make the connection effortless. The ultraFLOW STC has the same great features as other versions in the ultraFLOW family, a spill-free coupling that is highly durable and with extremely low pressure drop.
- Larger inner diameter, ideal for CDUs
- Unrivalled high flow and low pressure drop
- Saves energy and lowers investment costs
- Effortless connection and disconnection
- Option colour coding to indicate in or outgoing lines
