Linearis TE Ex 2/22
Fully electronic damper actuator for Ex-Zone 2 and 22
Advanced drive technology in a sturdy housing with compact dimensions. ARIS actuators of the series Tensor Ex are designed for industrial use in zones 2 and 22, which are potentially explosive, according to their marking. They are used for the actuation of regulating and shut-off devices, e.g. flaps, valves, ball valves, dosing pumps etc., and offer a high safety level. The robust, powder-coated housing and the metal hood of the drives ensure safe and reliable operation in zones 2 and 22. The wide range of mounting holes according to ISO 5211 and a change-over shaft system ensure simple assembly on all standard fittings without costly brackets. For the zones 2 and 22 no pressure-proof encapsulation is necessary so that the drive has significantly less weight than drives of the zone 1.
A stainless steel high-helix spindle with dryspin® spindle nut made of high-performance polymer ensures reliable and maintenance-free operation. Due to the high gradient, the required engine speed is noticeably reduced in comparison to the classic design, so that the engines run significantly smoother and quieter, thus significantly increasing the service life of the engines. Instead of the commercially available castings, anodised aluminum machined parts are used with the Linearis TE, which are significantly more robust with a low weight. The Linearis has been developed by practitioners. Long holes in the brackets allow easy assembly. The dry running spindle nut prevents dirt build-up so that large and expensive bellows designs are no longer required. Likewise, the regular greasing is avoided by the lubricant-free construction.
