Inmoco’s new Exlar EL 100 series of explosion-proof linear actuators improve loop performance and reduce process variability in critical valve and damper applications. The actuators integrate features specially developed for use in process applications: sophisticated velocity and positioning control, high speeds and forces, and the ability to carry heavy loads, reliably, for thousands of hours. In addition, the fully sealed, iP66 design of the EL100 series ensures highly reliable and trouble-free operation, even in the most severe and demanding environments.
The EL100 Series actuators are both ATEX – (Ex d II B T3 Gb IP66) and CSA -USA (Class I, Div 1, Groups B, C, D & T3) approved for use in potentially explosive environments. They are based upon a unique design that integrates a highly efficient planetary roller screw mechanism with a high torque servomotor in a single self-contained package. The roller screw outperforms rival ballscrews by a factor of 15, in terms of travel life and load carrying capacity. It consists of multiple threaded rollers assembled in a planetary arrangement around a threaded shaft. This highly robust design is designed to provide reliable and precise operation over thousands of hours.
The combination of the planetary roller screw and servomotor produces an all-electric actuator which is extremely compact, yet delivers similar performance to hydraulic actuators in terms of force (907 Kilograms max) and torque capability, while surpassing them in speed (up to 635mm/s), efficiency, positioning performance, operating life and environmental impact.
In demanding process applications, the EL100 actuator offers a unique combination of high speed, performance and accuracy in a compact package, plus the flexibility of compatibility with almost any resolver- based servo amplifier.
The optimised performance features of the EL 100 Series actuators are evident in valve and damper control applications, where the actuators continuously hold the position of the valve stem, or shaft, allowing extremely fast response to the smallest command signal changes, without overshoot, even when friction is present. This results in improved loop performance and reduced process variability.
Also optimising the EL100 series actuators for process applications is their excellent contamination protection. In conventional rotary to linear devices the critical mechanisms are exposed to the environment and therefore require frequent inspection, cleaning and lubrication. In contrast, all converting components in the EL-100 series actuator are mounted within the sealed motor housing, which is IP66 rated.
The explosion-proof rating, high performance and environmental packaging of the EL 100 series actuators mean that they are ideally suited to the widest range of applications. In addition to Valve and Damper control, these include: Shipboard fuel management systems, Fuel skids, Refineries, Engine test stands, Paint booths and Printing presses. In all of these applications the performance of the EL 100 Series actuators can be optimised with Exlar’s EXP Series of explosion proof positioners. These units also offer CSA Class I Division 1 and ATEX conformity: SIRA 10ATEX1037X Ex d II B T3 Gb IP66.
