Txij li thaum txoj cai siv ATEX kev qhia hauv Lub Xya Hli Ntuj 2003, kev tswj thiab kev saib xyuas cov qauv rau cov tshuab hluav taws xob tawg tau ua tshwj xeeb nruj. Qhov kev qhia no yuav muab cov tswv yim thermistor rau kev ntsuas kub rau lub tshuab kev ruaj ntseg thiab qhia hais tias tag nrho cov khoom yuav tsum ua raws li ATEX tus qauv. Vacon tau koom tes nrog German BGIA qhov chaw kuaj mob thiab VTT Technical Research Center hauv Finland los tsim ib qho kev kho thermal built-in thermal rau inverters uas muaj raws li ATEX certification requirements. Hauv xyoo 2006, Vacon lub cav siv lub tshuab hluav taws xob tiv thaiv kom tsis pub muaj kev tiv thaiv zoo dua rau daim ntawv qhia ATEX 94/9 / EC. Txawm hais tias qhov kev siv tshuab no tseem tsis cia tus inverter yuav muab ntsia tau rau hauv qhov chaw muaj kev phom sij, nws yog ib qho ntawm ob qho kev daws teeb meem muaj nyob hauv kev ua lag luam thiab tau siv rau qee yam. Kemfine chemical cog rau hauv Kokkola, Finland, ua cov tshuaj muaj yees paug rau cov agrochemicals thiab kws industries, yuav tsum siv kwv yees li ntawm 200 khoom thiab kua chemical thiab raw cov ntaub ntawv. Feem ntau ntawm nws qhov chaw tsim tshuaj muaj nyob hauv cheeb tsam muaj huab cua (qib tawg 1, khoom qib II2G). Yog li, kev nyab xeeb thiab ntsib ATEX cov kev cai kom ntau li ntau tau yog thawj yam haujlwm ntawm cov nroj tsuag.
Feem coob ntawm cov 1,250 motors hauv cov nroj tsuag yog cov tshuab hluav taws xob tawg, siv tag nrho cov kwv yees li ntawm 250 tus neeg ntawm cov tuam txhab txawv. Ntawm lawv, 30 Vacuum NXP inverters yog siv rau kev tsav tsheb ntawm cov khoom siv twj thiab cov agitators. Cov inverters siv lub tshuab kom muaj kev kub ntxhov los ntawm ATEX thermistor input technology. Vacon motor overheat protection technology siv tib lub ATEX-certified kev ruaj ntseg kev txwv kev ua haujlwm. Thaum ntsuas qhov kub thiab txias txias hauv lub tshuab hluav taws xob pom tias kub npaum li cas, lub inverter yuav kaw lub cav. Vacon NXP drives muaj cov cim tshwj xeeb ntawm cov khoom siv thermistor built-in uas yooj yim rau kev tswj thiab kev soj ntsuam cov tshuab hluav taws xob tawg uas piv rau cov qauv nruab nrab ntawm lub nruab nrog cov thermistor kev sib txuas lus thiab cov contactors. Raws li cov neeg siv, Vacon lub cev muaj zog tiv thaiv kub kub muaj ntau yam zoo. Daim duab circuit yog yooj yim thiab ncaj nraim, tshem tawm qhov xav tau rau thermistor relays, qhov taw qhia teeb thiab pib dua cov nyees khawm, uas ua rau tsawg dua yam tsawg dua cov pa ntsiab lus. Tsis tas li ntawd, lub tshuab hlwb hlau kuj tseem tuaj yeem txo qhov nyiaj ntawm cov siv los siv hauv chav fais fab, ua kev ntseeg ntau dua thiab txuag chaw thiab nqi. Thaum lub tswb tshwm sim, qhov ua rau tuaj yeem kuaj xyuas tau los ntawm lub chaw ua haujlwm hauv inverter lossis lub tsheb npav.
