Dell ‘Triton’ technology uses non-drip couplers to cool servers

Peak hours at data centres are spurring development of faster processes and improved performance. Dell, known for being one of the world's leading computer technology companies, uses CEJN quick-disconnect non-drip couplings in their liquid cooling solution called 'Triton'. The effective cooling technology allows high-performance components to run faster and more efficiently.

To meet end-user demand in development of the ‘Triton’ solution for data centres, Dell sought a drip-free quick-disconnect module to handle the delicate task of cooling each server sled effectively using water. Dell ended up with several promising proposals on the table, but preferred the look and performance of the CEJN couplers.

Special blind-mate coupling on filtration sled 
‘Triton’ incorporates two different sizes of CEJN quick connect couplings. The first, positioned on the side of the filtration sled, is a specially-produced Non-Drip Series 767 blind-mate drip-free coupling. The sled, which is vertically mounted, is guided into position and the blind-mate coupling is activated. It is then locked by a lever lock system. This gives a 100% drip-free solution to protect sensitive electronics. By cooling each server sled, ‘Triton’ uses 97 per cent less cooling power than regular air-cooled data centres*.

High-flow coupling feeds water to server 
The second type of coupling is used to deliver facility water into the filtration unit and then distribute the water to each of the IT server chassis within the remainder of the rack. To cool the server as efficiently as possible, we proposed again our high-flow Brass 767 coupling, from our Non-Drip series. This coupling has a flow capacity of Kv 13.30 with double shut-off, a figure that satisfied the demanding requirements of Dell’s development team. The high-flow Brass 767 coupling is, of course, also leak-free during connection and disconnection.

Quick feedback pays off
The good cooperation and communication between Dell and CEJN made it possible for us to react quickly to customer comments and provide high-quality prototypes that lived up to our promises: to be the best option  – an important catalyst that ultimately secured the deal.
