series CN

The CN series clean-break couplings (drybreak couplings) are designed for applications involving high flow rates and are used in particular in the chemical industry for the loading and transport of liquids and gases. They are also suitable for the high-volume loading of selected Group 1 media, such as gaseous hydrogen.

When loading large quantities of liquid, a secure, splash-free connection is crucial. Clean-Break couplings such as the CN series prevent media leakage and enable controlled coupling even when lines are full; as loading couplings, they allow safe and splash-free coupling and uncoupling even when hose lines are full, thereby increasing process reliability when loading large volumes.

As a low-pressure clean-break quick-coupling system with a cam-lock mechanism, they are primarily used for handling correspondingly large volumes at loading stations for lorries or trains carrying chemical liquids, liquid foodstuffs or their raw materials and additives, as dry couplings, dry-connect couplings or dry-break couplings. Further areas of application include their use as drip-free refuelling couplings.

For the high-volume transport of dangerous goods by road and rail, the CN series holds a TÜV certificate of type approval for the manufacture of transportable pressure equipment in accordance with Directive 2010/35/EU in conjunction with ADR/RID 2017 and DIN EN 14432:2014 → more information
