Series 687 ultraFLOW, DN15 Aluminium

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

The CEJN Series 687 ultraFLOW is especially suitable for the cooling systems in power electronics; transportation, industry, renewable energy but also in broadcasting and microelectronics such as CPU’s and GPU’s in data servers. This two-hand operated, lightweight, hard-coated, high strength aluminium connector has been provided with the best possible characteristics for applications where leaks are not an option! ultraFLOW’s smart design minimizes flow restrictions and provides a long-lasting connection, with non-leak performance during 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 extremely high flow combined with an unequalled low pressure drop to minimize system the 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, IGBTs, 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 under development. (Water Flow Series 687 DN15 PDF)
