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.

    High-helix: Hig­her life span and effi­ci­en­cy

    The dry­s­pin® tech­no­lo­gy is based on wear-resi­si­stant igus® high per­for­mance poly­mers, spe­ci­al­ly desi­gned for screw dri­ves, dry­s­pin® offers a hig­her life span and effi cien­cy to high-heli­xes by their cha­rac­te­ris­tics and geo­me­tries, spe­ci­al­ly matched to the nut and lead screw. By their free­dom from lub­ri­ca­ti­on, dry­s­pin® screw dri­ves are sui­ta­ble for usa­ge in rough indus­tri­al just as in clean and hygie­nic envi­ron­ments (e.g. labo­ra­to­ry auto­ma­ti­on).
