Nano + Ex 1

Elec­tro-mecha­ni­cal actua­tor for Ex-Zone 1

Clas­sic dri­ve tech­no­lo­gy in a rug­ged housing with com­pact dimen­si­ons. ARIS actua­tors of the series Nano+ Ex desi­gned for indus­tri­al use in zone 1 are­as. 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 clas­sic dri­ve tech­no­lo­gy of the Nano+ with syn­chro­nous or direct cur­rent motor allows a simp­le repla­ce­ment of actua­tors in exis­ting cir­cuits and sys­tems. The lar­ge num­ber of moun­ting holes accord­ing to ISO 5211 and a chan­ge-over shaft sys­tem ensu­re a simp­le con­struc­tion on all stan­dard fit­tings wit­hout cost­ly bra­ckets. The dri­ves of Zone 1 are cha­rac­te­ri­zed by a high level of intrin­sic safe­ty and ope­ra­tio­nal safe­ty.

  • Dri­ve

    Syn­chro­nous motor tech­no­lo­gy (AC) or direct cur­rent motor (DC)

    • The per­ma­nent magnets built into the syn­chro­nous motor ensu­re a high hol­ding tor­que even in a de-ener­gi­zed con­di­ti­on (AC)

    • The motor speed depends sole­ly on the vol­ta­ge fre­quen­cy. The­re­fo­re a con­stant and load-free actua­ting time is ensu­red.

  • Cutoff

    Clas­sic shut-off sys­tem via swit­ching cams and micro swit­ches

    • No vol­ta­ge sup­ply necessa­ry for posi­ti­on indi­ca­ti­on and shut-off. Nano actua­tors are 100% con­nec­tion com­pa­ti­ble to ARIS actua­tors sold befo­re 2014; per­fec­t­ly sui­ta­ble as exchan­ge actua­tors.

    • Tool-free adjus­ta­ble alu­mi­num swit­ching cams allow a fast and exact actua­tor set­up.

    • Addi­tio­nal fixa­ti­on pos­si­ble with Tuf­Lok thre­aded pins in the cam.
  • Mecha­ni­cal data

    Robust alu­mi­num housing

    • For usa­ge in rough indus­tri­al envi­ron­ment; high ope­ra­tio­nal safe­ty.

    • Impact-resistant cover pro­tec­ts reli­ab­ly all func­tio­n­al parts and ser­ves as opti­mal iso­la­ti­on of the elec­tric com­pon­ents; high ope­ra­tio­nal safe­ty.

    • Varie­ty of stan­dard retai­ning bores, incl. ISO 5211, allow an easy adap­ti­on of near­ly all val­ves wit­hout expen­si­ve moun­ting bra­ckets.

    • The com­pact design allows usa­ge even in con­s­tric­ted spaces.

    • Short deli­very times of spe­cial adap­ti­ons by a spe­cial chan­ge­ab­le shaft sys­tem.

  • Poten­tio­me­ter


    • Optio­nal poten­tio­me­ters allow con­ti­nuous feed­back of the cur­rent dri­ve posi­ti­on.
    • The poten­tio­me­ter auto­ma­ti­cal­ly adjusts its­elf to the tra­vel ran­ge by means of a slip clutch inte­gra­ted into the poten­tio­me­ter.
    • Various vari­ants allow opti­mum uti­li­za­ti­on of the ent­i­re poten­tio­me­ter ran­ge:
      Nano+ S 90 ° / 180 ° / 320 °, Nano+ M 20 … 40 Nm 90 ° / 160 °, Nano+ M 40 … 60 Nm 90 °, Nano+ L 90 ° / 180 ° / 320 °.
  • EX spe­ci­fi­ca­ti­ons

    • Can be used in Zone 1 and Zone 2Device cate­go­ries 2G and 3G
    • Pres­su­re-pro­of encap­su­la­ti­on “d”
    • App­li­ca­ble to gases with increa­sed igni­ti­on break­down capa­bi­li­ty “C”
    • Hig­hest tem­pe­ra­tu­re class T6
