COAX – The Double-Wall Tube System

Our COAX double-wall tube system offers reliable and efficient solutions for highly viscous, toxic, explosive or aggressive media in the semiconductor, chemical and biopharmaceutical industries. With an inner process tube and an outer safety tube, COAX ensures maximum process reliability and avoids dangerous and cost-intensive leaks.

Simple concept – dual protection

COAX tubes and fittings have an inner process tube and an outer safety tube between which, for example, a carrier gas reports leaks to a control room. Similarly, a pressure system can be connected, that detects leaks via a sensor-based measuring device. This allows safety-critical media leaks, such as those of acids or hydrogen, to be reliably monitored and minimizes downtime. Viscous media can also be kept in a liquid form in the inner process tube by using a tempered outer tube.

For the highest demands on the inner surface, the process tube is available in the electropolished Dockweiler Ultron quality. Alternatively, COAX is also available with a bright finished inner surface as a TCC process tube.

Design of the COAX tube system

1 Inner process tube (Ultron or TCC)
For explosive, toxic, aggressive or highly viscous media.

2 Outer safety tube  (TCC)
For safety or accumulation as well as for temperature-controlled media for heating or cooling.

3 VCR connector
The interface of the VCR connection enables sensory measurements.

Overview

The right inner surface for every application

The areas of application for our COAX tube system are just as diverse as the requirements for surface quality.

COAX tube systems with an electropolished process tube according to the Dockweiler Ultron specification ensure maximum process reliability.

For applications that have lower requirements for surface quality, COAX tube systems with an inner tube made of TCC offer an economical alternative.
