The Ultimate Extruder Protection device or UEP range of modular torque limiters from Bibby Turboflex, part of Altra Industrial Motion, has been developed to provide optimum protection against overloads and deliver maximum safeguarding against expensive failures and prolonged downtime on machinery. It offers users the key benefits of simplified installation; very accurate release torque repeatability, achieved with minimal variation between static and dynamic release; simple fast manual re-engagement; and low cost maintenance. 

The design of the UEP torque limiters has been based on 30 years’ experience in arduous applications and refined over time, culminating in the current range of products. This proven track record has led to the UEP range becoming the industry standard for twin screw extruders. 

The UEP range of modular torque limiters was designed specifically to offer an alternative to shear-pin protection for high torque drives where its accurate release torque repeatability coupled with the fast reset feature offers a significant reduction in downtime. Also, being relatively tamper-proof, it prevents unauthorized personnel from changing the release torque setting, which can range from 450 Nm to 15,000 Nm, depending on the application. 

The optimized design of the UEP torque limiters also means that installation is highly flexible, enabling the centre section of the torque limiter to be removed without the need to move the motor or gearbox. Similar design versatility ensures that any maintenance of the modules is a straightforward operation and that recalibration is a simple removal operation achieved without having to replace the complete torque limiter unit.
