Series 287 ultraFLOW, DN5 Aluminum

  • Unequaled low pressure drop
  • Lightweight and compact design
  • Colour coding option to eliminate cross connection
  • Universal connections for total flexibility

The CEJN Series 287 ultraFLOW is especially suitable for direct liquid cooled (DLC) server blades in data center applications, power electronics, transportation, industry, renewable energy but also in broadcasting. This two-hand operated, lightweight, hard-coated, high strength aluminum connector has been provided with the best possible characteristics for applications where leaks are not an option! Allowing for hot swaps to avoid critical system downtime when upgrading equipment, the ultraFLOW’s smart design minimizes flow restrictions and provides a long-lasting connection, with non-leak performance during connection / disconnection. It is resistant to vibrations and mechanical stresses, which is required in the railway traction sector. To give you maximum hardware output and low running costs, the ultraFLOW has an extreme high flow capacity meaning an unequaled low pressure drop to minimize system pressure required and, thus, reducing your Total Cost of Ownership.

Applications: High-performance computing racks/switch blades, chassis manifolds, cold plate, rack CDU manifolds, GPU manifolds, LED equipment, fuel cells, graphic cards, theatre projectors, medical imaging equipment, IGBT’s, power converters, power inverters, rectifiers, industrial drives. Are you looking for a different size or sealing? Don’t hesitate to contact us and we’ll put our R&D department at your disposal, other sizes are available and under development.
