Danfoss Hansen FD-83 coupling is designed for fluid transfer and electronics cooling applications where full flow, fluid compatibility and safety are essential.
--- Danfoss Hansen FD83 series dry break couplings are high-performance, leak-tight quick connectors engineered for liquid cooling systems in data centers. --- Featuring an interlock safety mechanism, the coupling can only open the internal flow path when the male and female halves are fully engaged. --- Before disconnection, the valve must be fully closed to prevent coolant spillage, which effectively protects equipment and reduces maintenance risks.
Danfoss Hansen FD83 series dry break coupling constructed from stainless steel with robust EPDM sealing rings, delivers excellent corrosion resistance and long service life under continuous cooling fluid circulation.
The full-flow internal design minimizes pressure drop and supports stable flow of ethylene glycol and other cooling media.
Equipped with barbed hose ports for simple hose assembly, these couplings come with protective caps to guard the sealing surface against dust and scratches during storage and transportation.
Typically deployed in cold plate liquid cooling loops for servers, FD83 quick disconnects enable fast, clean connection and disconnection for cabinet maintenance, upgrades or replacement.
