NTS®-SZ-CS: Emergency disconnect safety system with cable pull for aggressive media

The NTS®-SZ-CS is a breakaway coupling with a cable pull system designed to transport aggressive media due to its material composition. Its innovative separation mechanism ensures non-destructive, safe separation during hazardous situations and its reassembly is rapid and easy. Its maximum range of activation is 360°, and its triggering mechanism functions independently of system pressure at the facility.
Hazardous events often arise during refueling operations due to an accidental impact on the line. This can occur for a variety of reasons, such as the sudden departure of a tanker connected to the coupling. To avoid such a problem, the line should be provided with an NTS emergency disconnect safety system from ARTA.

When an inadvertent tensile force act on the line where the NTS®-SZ-CS is installed, the two coupling halves separate in a controlled manner and the valves close on both sides. No spillage of potentially dangerous media will occur and operator safety is ensured.

Resistance to aggressive media

The NTS®-SZ-CS is predominantly constructed of plastic and has been specially developed for use with aggressive inorganic and organic substances, such as acids and alkalis.

Non-destructive separation

The design of the NTS®-SZ-CS separates safely and directly, keeping coupling components intact. This ensures a long service life for the NTS. Furthermore, the separation mechanism permits spill-free retention storage of the media in both coupling halves. There is no impact on the environment and there are no additional material costs.

Quick and easy reassembly on site

The task of reassembling a disconnected Breakaway Coupling is quick one, because separation is not destructive. The separated halves are united with a simple device rather than special tools or spare parts, and unnecessary downtime is thus avoided.

Maximum flow

The flow-optimized NTS®-SZ-CS design was created using the finite element method (FEM) validated by flow tests. The results show that pressure loss is minimal when the breakaway coupling is at maximum delivery flow.

Patented trigger mechanism with fully flexible 360° range of activation

The optimized release mechanism prevents a pulling action between a vehicle, the NTS and the remainder of the system. In this manner, safe separation is ensured even under bad conditions. The fully flexible 360° range of activation allows separation regardless of the direction in which a tensile force is exerted on the system, and the high-performance triggering mechanism of the NTS®-SZ-CS remains unaffected by line pressure.

Fully verified by international certification entities

The NTS®-SZ-CS is safety-certified by international approval organizations and maintains a position of worldwide recognition for operator and environmental safety. Among the global industry, no safety-related reservations regarding its use exist.
ARTA Breakaway Couplings are used on suction and discharge lines for liquid, gaseous or solid substances. Because they can be employed on both hose lines and on pipe loading systems, they are ideal for tanker trucks, tanker ships, loading stations or hose towers, among other applications.

The NTS®-SZ-CS was specially developed for the transport of aggressive media such as acids and alkalis. Ideally, they are combined with our ASK®-KS-HD Dry Break.
