ASK®-TT: Cryo Dry Break Couplings down to -328°F (-200°C)
The ASK®-TT cryo dry break coupling, for low-temperature applications, handles liquid and gaseous media in suction or pressure lines. Connections can be completed without drips, safely, and environmentally friendly. It enables fast coupling and uncoupling, even with filled lines subject to working pressure. Moreover, the integrated swivel joint minimizes mechanical wear to ensure a long life-cycle. Cryogenic dry-break couplings are recommended for transporting LNG, LOX, and other liquid or gaseous media down to -200° Celsius or -328° Fahrenheit, respectively.
How does ARTA's ASK®-TT work?
Connecting and disconnecting the ASK-TT dry break coupling is fast and straightforward. The female coupler can connect to the male adapter with a single, continuous rotation. The coupler seals first, and then the internal valves are opened. The media therefore remains entirely inside the product line, without exposure to the environment. Reverse the order for disconnection. The coupling valves close and seal fully before the female coupler can be de-coupled from the male adapter. Therefore, no loss of media occurs during the disconnection process. Generally, the male adapters are fixed to manifolds, trucks, ships, etc. The female couplers are connected to hose lines or loading arms.
What are the advantages of ARTA's ASK®-TT?
✓ Reliable, even at low temperatures
The ASK-TT allows for the transfer of liquids and gases in a low-temperature range (down to -200° Celsius or -328° Fahrenheit, respectively). Even subject to a degree of icing, the ASK-TT remains fully functional. Thus, operators can use it for virtually any cryogenic application.
✓ Drip-free & safe
The internal valves of the ASK-TT ensure a drip-free coupling and uncoupling process. Neither the environment nor the end-user are exposed to the cryogenic media.
✓ Faster transfers
You can safely uncouple the ASK-TT even with a filled line, which significantly speeds up the loading process. The simple handling of the dry break coupling also minimizes the time required to establish a connection. The ergonomically optimized handwheel also makes the operation much easier compared to a conventional handle.
✓ Maximum flow
We determined the flow-optimized design of the ASK-TT using the finite elements method (FEM), and we validated our design with live flow tests. As a result, the ASK-TT dry break coupling achieves a maximum conveying volume with minimal pressure loss.
✓ Integrated swivel joint
The integrated swivel joint in the female coupler minimizes mechanical stress and prevents torsion load on the line. Additionally, the high-quality design of the dry coupling ensures a continuously smooth rotation of the swivel joint. The ASK-TT is, therefore, a very low-maintenance coupler.
✓ 100% verified by international accreditation bodies
The ASK-TT is a globally recognized safety product that has been certified by well-known, international certification bodies. As a result, their use in critical applications is possible without reservations.
