MannTek Dry Cryogenic Couplings

  • Self locking quick connect/disconnect coupling, to ISO21593 TS 18683.
  • Suitable for the loading and unloading of cryogenic liquified gases (LNG, nitrogen, oxygen, argon, ethylene etc.) down to -196°C.
  • Tank unit without swivel, typically fix mounted as filling connector for container discharge, fuel bunkering truck-to-ship, ship-to-ship, terminal-to-ship, loading/unloading of tank trucks, rail tankers and ships.
  • Hose unit with swivel, typically mounted on hose assemblies & loading arms for temporary connection between storage tank & mobile transport units, e.g. for container discharge, fuel bunkering, loading/unloading of tank trucks, rail tankers and ships.
  • Quick and safe connection of hose assemblies and loading arms to mobile and stationary tanks, under pressure and with minimised product loss.
  • During the cool-down phase, no retightening of the connection is necessary as practiced with flanged or threaded connections.
  • Both coupling parts are equipped with a flat poppet valve. For the connection, the hose unit is pushed onto the tank unit & coupled/sealed by turning the coupler clockwise by 15°.
  • When the unit is turned by 100 degrees, the valves move into the tank unit so that the medium can flow.
  • When a similar turn is made counter-clockwise, the flow is stopped and the coupler can be pulled off.
  • Sizes range from 1" (DN25) up to 6" (DN150).
  • Connections are NPT thread, DIN/ANSI flange - others on request.
  • Pressure - can be coupled up to 7 bar line pressure.
  • Working Pressure - DN25 - DN100 is 25 bar, DN150 is 16bar.
  • Temperature - between -196°C up to +85°C.
  • Material - Body: stainless steel 1.4404 (AISI 316L). O-rings: PTFE.
