Safe and Efficient Filling of Gas Cylinders with Collar/Bead

The new WEH® Connector TW103-S90 has been specially developed for the industrial filling of CO₂ gas cylinders with collar/bead and residual pressure valve. With this innovation, WEH expands its portfolio to enable safe and efficient filling of gas cylinders with collar/bead—a milestone in the gas industry.

Since 1983, WEH has been setting standards in the development and production of quick connectors for the gas industry. The portfolio includes gas connectors for cylinder valves with female or male threads, pin index, with or without residual pressure valve, and for various gases and gas mixtures such as inert gases, oxygen, nitrogen, propane, acetylene, CO₂, medical gases, and many more.

Equipped with state-of-the-art technology and the highest safety standards, the new TW103-S90 gas adapter ensures precise, fast, and efficient filling - even under demanding conditions.

Filling gas cylinders with collar/bead requires the highest level of precision and process reliability. The TW103-S90 meets these demands flawlessly:

• Fast connection and disconnection: The expandable jaw locking mechanism ensure a secure and pressure-tight connection with the cylinder valve's contour.
• Pneumatic assistance: A precise control system facilitates connectors positioning, controlled opening and closing of the RPV in the cylinder valve, and safe venting of the connector.
• Process control: Using two external pneumatic lines, the residual pressure valves in the cylinder valve can be opened and closed directly from the control panel - a significant advantage for automated systems.
• Pressure-tight connection: The expandable jaw locking mechanism provide a secure seal for the cylinder valve, ensuring a reliable CO₂ filling process.
   

The unique properties of CO₂ and gas cylinders with collar/bead require specific safety measures. The TW103-S90 offers the following features:

• Vent Holes: Lateral gas discharge in case of unintended leakage protects the environment and prevents hazards.
• Pneumatically controlled vent valve: Ensures safe operation even with residual pressure in the system, eliminating the need for manual pressure release.
• Optional sensor integration: A safety sensor monitors the connection position, providing additional process security.

Ideal for Industrial CO₂ Applications

The TW103-S90 has been designed to meet the specific requirements of CO₂ production and filling systems. It is perfectly suited for:

• Vertical in-line CO₂ filling
• Operation in temperatures from -40 °C to +40 °C
• Working pressure up to 155 bar

Its compact design allows for seamless integration into existing systems, while its robust construction ensures reliable performance—even under high operational demands.
