PICO – The Bridge bet­ween HCV- and Indus­tri­al Actua­tors

Aris Stell­an­trie­be deli­vers with the PICO an actua­tor of extra­or­di­na­ry fle­xi­bi­li­ty. Based on a Heating, Clima­te con­trol and Vent­i­la­ti­on tech­no­lo­gy actua­tor, the “PICO” offers many cha­rac­te­ris­tics, which are requi­red in indus­tri­al app­li­ca­ti­ons.

The com­pa­ny from Trois­dorf (North Rhi­ne-West­pha­lia) spe­cia­li­zes in elec­tric and pneu­ma­tic actua­tors. All Aris pro­duct series are sub­ject to an ongo­ing evo­lu­tio­na­ry pro­cess, from which in part deve­lop fur­ther enhan­ce­ments and as well com­ple­te­ly new series. Enhan­ce­ments are often in details, making howe­ver altog­e­ther a tre­men­dous dif­fe­rence. With the ambi­ti­on to deve­lop long-las­ting, prac­ti­cal solu­ti­ons, the actua­tor series PICO has been crea­ted offe­ring con­su­mers pri­ce­wi­se attrac­tive devices wit­hout any loss in qua­li­ty in com­pa­ri­son with indus­tri­al high-end actua­tors. The PICO pro­duc­tion line is par­ti­cu­lar­ly inte­res­ting for OEM custo­mers, as its modu­lar design enab­les cus­to­mi­zed equip­ment. The PICO pro­duc­tion line lay­out is for high volu­me series, thus making the eco­no­mic bene­fit par­ti­cu­lar­ly signi­fi­cant.

By default, the PICO has pro­tec­tion class IP65 and assu­res, based on its ultra­so­nic-wel­ded casing, mini­mal vul­nera­bi­li­ty against dirt and con­ta­mi­na­ti­on. Its com­pact design faci­li­ta­tes its instal­la­ti­on, even in tight­ly dimen­sio­ned plant lay­outs. For examp­le, optio­nal swit­ches and poten­tio­me­ters are insi­de in the pro­tec­tive casing as gene­ral­ly used in indus­tri­al app­li­ca­ti­ons, and not atta­ched as addi­tio­nal body with sepa­ra­te cable con­nec­tion. Set­tings and adjust­ments are made con­ve­ni­ent­ly from out­si­de. The pos­si­bi­li­ty of an inte­gra­ted spring reset is avail­ab­le as well. The actua­tor is rea­dy for direct moun­ting on a gre­at num­ber of thrott­le val­ves, ball val­ves, and mixing val­ves. In con­trast to other pri­ce­wi­se com­pa­ra­ble pro­duc­ts, Aris pro­vi­des an own acces­so­ry pro­gram with an appro­pria­te selec­tion of com­pon­ents accord­ing to the requi­re­ments of the indus­try. From spa­cer moun­ting kits and posi­ti­ve locking redu­cers to clam­ping adap­ters, and modu­lar enhan­ce­ments offer custo­mers mul­ti­ple alter­na­ti­ves.

Per­for­mance as requi­red

The com­pa­ny Aris Stell­an­trie­be com­ple­men­ted sen­si­b­ly its port­fo­lio pro­vi­ding with actua­tors of up to 500Nm and the recent addi­ti­on of the PICO pro­duct fami­ly appro­pria­te solu­ti­ons in both, the upper and lower per­for­mance ran­ge. After mar­ket launch, matching PICO vari­ants for ball val­ve and thrott­le val­ve app­li­ca­ti­ons are avail­ab­le ex stock; later cus­to­mi­zed vari­ants for OEM-custo­mers are pos­si­ble.

ARIS nano gro­wing “big”

In the past 5 years, the com­pa­ny ARIS Stell­an­trie­be GmbH from Trois­dorf com­ple­te­ly moder­ni­zed its pro­gram of elec­tric actua­tors. Com­pa­red to the full-elec­tro­nic Ten­sor pre­cisi­on actua­tor series, the nano ran­ge fol­lows the con­ven­tio­nal actua­tor con­cept with syn­chro-motor and cam­shaft, based on up-to-date tech­no­lo­gy and modern pre­sen­ta­ti­on.

The nano ran­ge, until now built with a maxi­mum tor­que of up to 180 Nm has been expan­ded, pre­sen­ting the new XL series with 500 Nm at the “Val­ve World 2018”.
All optio­nal com­pon­ents and elec­tro­nic boards of the nano series are as well avail­ab­le and appro­pria­te for use with the nano XL ran­ge.

The par­ti­cu­lar high­light of the nano XL ran­ge is again the direct con­nec­tion of trip cam and dri­ve shaft, so that con­trol cams and poten­tio­me­ter are working free from back­lash. This way, pre­cisi­on and accu­ra­cy is con­si­der­a­b­ly increa­sed. Now, set­tings and hand­ling is iden­ti­cal for all models from size S up to size XL.

Ten­sor” now avail­ab­le wit­hout per­ma­nent power sup­ply

For the ful­ly elec­tro­ni­cal­ly con­trol­led “Ten­sor” actua­tor from ARIS, now is avail­ab­le a “Repla­ce­ment Modu­le”. This vari­ant makes pos­si­ble ope­ra­ti­ons wit­hout con­ti­nuous sup­ply vol­ta­ge.

Sin­ce its mar­ket launch in 2015, Tensor‘s pro­duc­tion out­put increa­sed at a very rapid pace. More and more custo­mers of ARIS Stell­an­trie­be GmbH are con­vin­ced of the easy set­ting mode via key­board and dis­play, its non-wea­ring pre­ci­se regu­la­ti­on, and the built-in pre­cisi­on gear. Com­bi­ned with a fle­xi­b­ly adjus­ta­ble regu­la­ting ran­ge and the mul­ti-vol­ta­ge power pack, many ARIS custo­mers were able to redu­ce con­si­der­a­b­ly the varie­ty of actua­tor types in use and their logistics costs.

In con­trast to an instal­la­ti­on in a new plant, repla­ce­ment of con­ven­tio­nal actua­tors invol­ved a cer­tain effort and cost due to the Tensor’s need of con­ti­nuous vol­ta­ge sup­ply. Ans­we­ring fre­quent custo­mer requests, ARIS Stell­an­trie­be GmbH deci­ded to deve­lop the “Repla­ce­ment Modu­le”, gene­ra­ting the requi­red sup­ply vol­ta­ge from the “clock­wi­se” respec­tively “anti-clock­wi­se” con­trol pul­se. In com­bi­na­ti­on with a spe­cial power pack, spe­ci­fi­cal­ly desi­gned for the Ten­sor, with extre­me­ly short run-up times, the Ten­sor with “Repla­ce­ment Modu­le” direc­t­ly plug­ged onto the mother­board like other optio­nal modu­les, is now fit for ser­vice wit­hout con­ti­nuous sup­ply vol­ta­ge. Now, con­ven­tio­nal actua­tors are rea­dy for use in 3‑point step-by-step mode.
