Expo Technologies是危險(xiǎn)區(qū)域保護(hù)的。我們與廣泛行業(yè)的終用戶，集成商和OEM合作，包括石油和天然氣，化學(xué)和石化，制藥和生物技術(shù)以及發(fā)電。
利用我們?cè)诜秶鷥?nèi)對(duì)安全標(biāo)準(zhǔn)的豐富了解，我們可以在危險(xiǎn)和環(huán)境中為客戶提供服務(wù)。
我們?cè)谟?guó)，美國(guó)和中國(guó)設(shè)有制造中心，并通過授權(quán)渠道合作伙伴網(wǎng)絡(luò)在范圍內(nèi)運(yùn)營(yíng)。
思考+設(shè)計(jì)+認(rèn)證
思考–憑借60多年的經(jīng)驗(yàn)，我們利用我們?cè)贓x p，Ex e，Ex d和Ex i方面的專業(yè)知識(shí)專注于解決危險(xiǎn)區(qū)域問題。
設(shè)計(jì)–我們開發(fā)滿足客戶需求的工程解決方案。無論是提供標(biāo)準(zhǔn)產(chǎn)品還是根據(jù)客戶的*需求創(chuàng)建定制解決方案。
認(rèn)證–我們所有的產(chǎn)品和定制解決方案均已通過和國(guó)家標(biāo)準(zhǔn)認(rèn)證，并受到行業(yè)的信賴。
五十多年來，Expo Technologies一直為的海上，石油，天然氣，煉油，石化，化學(xué)，制藥，生物技術(shù)，工業(yè)制造和海洋工業(yè)提供優(yōu)質(zhì)的產(chǎn)品和服務(wù)。
我們的專業(yè)知識(shí)為許多的工業(yè)園區(qū)的安全運(yùn)行做出了貢獻(xiàn)，在這里，我們的產(chǎn)品可以保護(hù)各種設(shè)備。 示例包括大型電動(dòng)機(jī)和發(fā)電機(jī)，壓縮機(jī)和泵驅(qū)動(dòng)器，電動(dòng)機(jī)控制中心，開關(guān)設(shè)備和儀器儀表，分布式控制（DCS）系統(tǒng)，控制面板，過程分析儀，狀態(tài)監(jiān)視系統(tǒng)，焊接機(jī)和計(jì)算機(jī)硬件。
世博會(huì)還使用我們的吹掃和加壓裝置為環(huán)境保護(hù)提供解決方案，以防止灰塵，腐蝕性和其他無害氣體污染安裝在接近過程應(yīng)用的機(jī)柜中的電氣設(shè)備。
X-Purge: Inert gas or compressed air purge
Install any electrical equipment in a Zone 1 or Class I Div 1 hazardous gas area. X-Purge units:
- Feed a continuous flow of compressed air or inert gas through the enclosure to purge hazardous gases;
- Monitor the compressed air or inert gas outflow, not the inflow, to ensure hazardous gases are indeed purged, then,
- Maintain a positive pressure to stop hazardous gas entering the enclosure or cabinet.
X-Purge units are:
- Automatic:
- Timers and control signals apply and disengage power depending upon conditions reported by the purge system.
- Complete with:
- Control unit;
- Spark arrestor;
- Relief valve.
- For all enclosure sizes: Expo designed our X-Purge line for all sizes of enclosure
- Certified:
- ATEX,
- cFMus,
- cULus,
- IECEx,
- INMETRO.
For power isolation devices, please see our complete line of MIU’s (MiniPurge Interface Units) .
