NORMA Group develops new eM Twist for battery powered vehicles

NORMA Group has developed a new quick connector for battery‐powered vehicles. The eM Twist is extremely light and is space‐saving on installation, so it is ideally suited for the usage in thermal management systems in e‐cars and hybrids. The eM Twist was developed for the VDA type spigot and it can be used in cooling water applications. Its assembly‐friendly self‐locking mechanism can be securely locked with a single movement and opened without tools by twisting the locking ring.

“The shift in vehicle drives towards lower‐emission technologies offers enormous potential for us,” says Dr Michael Schneider, CEO of NORMA Group. “It is important to meet customer requirements precisely. With the eM Twist, we are expanding our portfolio for the growing electromobility market with an easy‐to‐install solution without compromising on safety.”

The eM Twist is optimised for use at operating temperatures of up to 110 °C and a maximum operating pressure of 2.5 bar, geared to the temperature range and pressure requirements of electrically powered vehicles. Its low assembly force makes it easy to install.

During development, NORMA Group's engineers concentrated on the essential components and the best possible use of materials. The connector saves around a third of CO2 in production and the supply chain compared to similar connectors in conventional cooling systems. The main reasons for this are the optimised use of raw materials in product design and less emissions through transport of the components.

Production of the eM Twist will initially start at NORMA Group’s plant in Pilica, Poland. In the future, production can be expanded to other locations.
