LINEA­RIS goes ATEX – New ARIS Line­ar Moti­on Dri­ve gets “Ex” Design

ARIS Stell­an­trie­be GmbH has pre­sen­ted its new dam­per actua­tor LINEA­RIS during the tra­de shows DIAM and Val­ve World in 2014. This latest in-hou­se deve­lop­ment was well accep­ted and ARIS recei­ved several sug­ges­ti­ons to offer the­se line­ar moti­on dri­ves in a design which is sui­ta­ble for use in explo­si­ve atmo­s­phe­res of zone 1.

ARIS is said to be spe­cia­list for indus­tri­al dri­ve tech­no­lo­gy with expe­ri­ence of over 40 years and per­ma­nent mar­ket ori­en­ta­ti­on. The­re­fo­re the ARIS deve­l­oper team has modi­fied the exis­ting ATEX dri­ve and imple­men­ted the LINEA­RIS Ex in the shor­test time.

Actua­tors of the Intel­li­gent Line and the Clas­sic Line are used as dri­ve heads. The­se are, as alre­ady the rota­ry and part-turn actua­tors, instal­led in a sepa­ra­te fla­me­pro­of enclo­sure, ther­e­by ful­fil­ling all the requi­re­ments use in zone 1.

The risk assess­ment in accord­ance with ATEX — Direc­tive 94/9/EC show­ed that the LINEA­RIS lift unit can be used with minor modi­fi­ca­ti­ons in hazar­dous are­as of zone 1. Here, the new LINEA­RIS lift unit plays from their advan­ta­ge over dam­per actua­tors sold until 2014, sin­ce the unit is not firm­ly con­nec­ted to the dri­ve head, but can be com­bi­ned with various dri­ve heads.

Of cour­se, the LINEA­RIS in Ex ver­si­on is main­ten­an­ce-free, in con­trast to ear­lier models. Due to the pos­si­ble use of the Intel­li­gent Line dri­ve heads, the ARIS custo­mers get in all the bene­fits of a ful­ly elec­tro­nic actua­tor. The­se inclu­de exact ope­ra­ting time and tor­que con­trol, secu­ri­ty fea­tures by con­ti­nuous dri­ve moni­to­ring, easy set up, mul­ti-vol­ta­ge power sup­ply (90–265 VAC), soft start/stop, etc. If for indi­vi­du­al app­li­ca­ti­ons the clas­sic dri­ve tech­no­lo­gy with syn­chro­nous motor and switch cam is suf­fi­ci­ent, par­al­lel dri­ve heads of the Clas­sic Line can be used.
