Nano+ Ex 2/22

Elec­tro-mecha­ni­cal actua­tor for Ex-Zone 2 und 22

The Nano+ offers clas­sic dri­ve tech­no­lo­gy in a modern design. The clas­sic actua­ti­on dri­ve sys­tem, con­sis­ting of a motor-gear­box com­bi­na­ti­on and a switch-off sys­tem con­sis­ting of swit­ching cams and microswit­ches, is still valid today. For this rea­son, the Nano+ series was com­ple­te­ly rede­si­gned on the basis of the Nano in 2014, sin­ce clas­si­cal dri­ve tech­no­lo­gy is not necessa­ri­ly equi­va­lent to “old tech­no­lo­gy”. All con­ceiva­ble opti­ons have been taken into account in the new design and have been desi­gned in such a way that they are always firm­ly in place and offer opti­mum ope­ra­tio­nal safe­ty thanks to an opti­mal covering of all vol­ta­ge-car­ry­ing parts.

A height-adjus­ta­ble and pow­der-coated alu­mi­num hood in com­bi­na­ti­on with the pow­der-coated basic housing also ensu­re a worry-free use even in the har­shest indus­tri­al envi­ron­ment. In addi­ti­on, safe swit­ching cams ensu­re a safe switch-off in the set posi­ti­on even in the case of strong vibra­ti­ons. The height-adjus­ta­ble metal hood allows a mul­ti­tu­de of addi­tio­nal opti­ons ran­ging from mul­ti­turn app­li­ca­ti­ons to fast respon­se times with high tor­que and fail-safe func­tion for the DC vari­ant.

Test insti­tu­tes con­fir­med the sui­ta­bi­li­ty for the elec­tro­nic cir­cuit accord­ing to DIN EN 12067–2 and / or in poten­ti­al­ly explo­si­ve atmo­s­phe­res of Zone 2 or 22. The All­roun­der Nano+ is avail­ab­le in vol­ta­ges of 230 V, 115 V, 24 V AC or 24 V DC and fits in almost any app­li­ca­ti­on in all indus­tri­al app­li­ca­ti­ons.

  • 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 II 3D Ex tc IIIC T80°C Dc X (Zone 22)
      Ambi­ent tem­pe­ra­tu­re: –15 °C ≤ Ta ≤ 45 °C
    • Com­pact design (Dimen­si­ons and spe­ci­fi­ca­ti­ons as stan­dard dri­ve N+)
    • Small surch­ar­ge from stan­dard dri­ve, lower pri­ce than with pres­su­ri­zed encap­su­la­ti­on
    • App­li­ca­ble in Zone 2 or 22
    • Dimen­si­ons and spe­ci­fi­ca­ti­ons as stan­dard dri­ve
    • High safe­ty by sin­gle check at fac­to­ry
