功能：PTC空氣加熱<\/strong><\/span> <\/p>

<\/strong>特點(diǎn)：自動(dòng)恒溫/熱效率高/安全可靠壽命長(zhǎng)/速度快/低耗節(jié)能環(huán)保！<\/strong><\/span> <\/p>

PTC發(fā)熱片功率大小與散熱有關(guān)，散熱越好功率越大，建議配合風(fēng)扇使用效果**！<\/span><\/strong><\/span><\/span> <\/p>

<\/span><\/strong><\/span><\/span> <\/p> <\/span><\/strong><\/span><\/span>     風(fēng)道式電加熱器主要用于風(fēng)道中的空氣加熱，規(guī)格分為低溫、中溫、高溫三種形式，在結(jié)構(gòu)上的共同之處是采用鋼板支撐發(fā)熱管以減少<\/span><\/span>發(fā)熱管<\/span>的振動(dòng)，接線盒中都裝有超溫控制裝置。另在控制方面除裝有超溫保護(hù)外，還在風(fēng)機(jī)與加熱器之間加裝聯(lián)運(yùn)裝置，以確保電加熱器啟動(dòng)必須在風(fēng)機(jī)起動(dòng)之后，在加熱器前后加一差壓裝置，以防風(fēng)機(jī)故障，風(fēng)道式電加熱器加熱的氣體壓力一般不應(yīng)超過<\/span><\/span>0.3<\/span>公斤每平方厘米，如需超過以上壓力，請(qǐng)選用循環(huán)式電加熱器；低溫型加熱器氣體加熱溫度不超過<\/span>150<\/span>℃；中溫型不超過<\/span>260<\/span>℃；高溫型不超過<\/span>500<\/span>℃。<\/span>
風(fēng)道式PTC電加熱器主要是用來(lái)將所需要的空氣流從初始溫度加熱到所需要的空氣溫度，可達(dá)<\/span>200<\/span>℃。已被廣泛的應(yīng)用到烘道，烘房，老化房，高溫房等。特別適合于自動(dòng)控溫和大流量高溫加熱器。風(fēng)道式電加熱器使用的范圍寬：可以對(duì)任何氣體加熱，產(chǎn)生的熱空氣干燥無(wú)水份、不導(dǎo)電、不燃燒、不**、無(wú)化學(xué)腐蝕性、無(wú)污染、安全可靠、被加熱空間升溫快（可控）。<\/span> <\/span>
單臺(tái)功率從<\/span>2KW<\/span>～<\/span>500KW<\/span>系列。<\/span>
使用須知<\/span>Notice:<\/span>
控制方面，必須在風(fēng)機(jī)與加熱器之間加一聯(lián)動(dòng)裝置，以確保加熱器起動(dòng)<\/span>,<\/span>需在風(fēng)機(jī)起動(dòng)工作之后進(jìn)行。在加熱器停止工作后，風(fēng)機(jī)必須延時(shí)工作<\/span>3<\/span>分鐘以上，以防加熱器過熱而損壞。在單回路接線方面必須符合<\/span>NEC<\/span>標(biāo)準(zhǔn)，每一支路電流不得超過<\/span>48A<\/span>。通道加熱器加熱的氣體壓力一般不超過<\/span>0.3kg/cm2<\/span>，如要超過以上壓力規(guī)格，請(qǐng)選用循環(huán)式加熱器。低溫型加熱器氣體加熱的溫度不超過<\/span>150<\/span>℃；中溫型不超過<\/span>250<\/span>℃，高溫型不超過<\/span>500<\/span>℃。<\/span>
風(fēng)道式加熱器的安裝形式包括：<\/span>
對(duì)接安裝，<\/span>
插入式安裝，<\/span>
分口安裝，<\/span>
入口安裝等安裝方式。<\/span>
用戶根據(jù)實(shí)際情況，可以選擇各種合適的安裝方式<\/span>

一般外殼材料采用碳鋼，或者不銹鋼、鍍鋅板<\/span>
而風(fēng)道式電加熱器加熱部分大多采用不銹鋼材料，選用時(shí)，如材料碳鋼材料需要特殊說(shuō)明。<\/span><\/span> <\/div>
