COAX: Safety and efficiency for media transport

Maximum safety and efficiency for sensitive media transport

Safe transportation for demanding media: Our COAX double-wall tube system guarantees efficient solutions for toxic, explosive or highly viscous media. With an inner process tube and an outer safety tube, COAX tubes and fittings offer maximum safety. Thanks to innovative technology, they report leaks immediately to the control station or keep viscous media liquid through steam. Easy to retrofit into existing systems, they guarantee maximum process reliability and help to prevent costly and dangerous leaks.
