ATEX Rated Explosion-Proof Linear Actuators from Exlar Provide a Cost-Effective Solution for Even the Most Demanding Environments

The EL Series linear actuators integrate a highly efficient planetary roller screw mechanism with a high torque servomotor in a single self-contained package. The roller screw consists of multiple threaded rollers assembled in a planetary arrangement around a threaded shaft. This highly robust design is engineered to provide reliable and precise operation over thousands of hours, handling heavy loads even under extremely demanding conditions.

Exlar’s servo-electromechanical systems offer clean, fast, simple and cost effective replacements for hydraulic actuation and longer lasting alternatives to pneumatic actuation. Reduced emissions and energy consumption (80% system energy efficiency) as well as increased position control and accuracy—all leading to reduced cost—are provided by servo electric actuation. Other features that make Exlar’s servo-electromechanical systems particularly easy to set-up and use include:

Speeds up to 25 ips
Forces up to 2000 lbs
8 pole brushless motors
Strokes up to 6 in.
Feedback configurations for nearly any resolver-based servo amplifier
Several mounting configurations
Windings available from 24 VDC to 460 Vrms
CSA Class I, Div 1 Group B, C, D and T3 hazardous environment rating
ATEX II 2 G Ex d IIB T3 Gb IP66
Completely sealed motor for trouble-free operation
For process applications, the EL100 offers a unique combination of high speed, performance and accuracy in a compact package when coupled with Exlar’s EXP Series Positioner. High performance is achieved with respect to speed, linearity, load sensitivity, deadband and temperature range. For valve and damper control, the EL Series 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.

EL Series explosion-proof actuators are well-suited to many applications, such as:

Valve control
Damper control
Printing presses
Engine test stands
Fuel skids
Refineries
Paint booths
Shipboard fuel management
Exlar’s EL Series provide a superior and cost-effective solution even in the most severe and demanding environments.
