Expo Technologies是危險區(qū)域保護的。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,，化學和石化,，制藥和生物技術以及發(fā)電。
利用我們在范圍內(nèi)對安全標準的豐富了解,，我們可以在危險和環(huán)境中為客戶提供服務,。
我們在英國，美國和中國設有制造中心,，并通過授權渠道合作伙伴網(wǎng)絡在范圍內(nèi)運營,。
思考+設計+認證
思考–憑借60多年的經(jīng)驗，我們利用我們在Ex p,，Ex e,，Ex d和Ex i方面的專業(yè)知識專注于解決危險區(qū)域問題。
設計–我們開發(fā)滿足客戶需求的工程解決方案,。無論是提供標準產(chǎn)品還是根據(jù)客戶的*需求創(chuàng)建定制解決方案,。
認證–我們所有的產(chǎn)品和定制解決方案均已通過和國家標準認證，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,，制藥,，生物技術，工業(yè)制造和海洋工業(yè)提供優(yōu)質的產(chǎn)品和服務,。
我們的專業(yè)知識為許多的工業(yè)園區(qū)的安全運行做出了貢獻,，在這里，我們的產(chǎn)品可以保護各種設備,。 示例包括大型電動機和發(fā)電機,，壓縮機和泵驅動器，電動機控制中心,，開關設備和儀器儀表,，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)，焊接機和計算機硬件,。
世博會還使用我們的吹掃和加壓裝置為環(huán)境保護提供解決方案,，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用的機柜中的電氣設備,。 

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) .

• SmartPurge II (SP2-PX-ss)
