功能：PTC空氣加熱<\/strong><\/span> <\/p>

<\/strong>特點：自動恒溫/熱效率高/安全可靠壽命長/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，建議配合風扇使用效果**！<\/span><\/strong><\/span><\/span> <\/p>

<\/span><\/strong><\/span><\/span> <\/p> <\/span><\/strong><\/span><\/span>     風道式電加熱器主要用于風道中的空氣加熱，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，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外，還在風機與加熱器之間加裝聯(lián)運裝置，以確保電加熱器啟動必須在風機起動之后，在加熱器前后加一差壓裝置，以防風機故障，風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>
風道式PTC電加熱器主要是用來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<\/span>200<\/span>℃。已被廣泛的應(yīng)用到烘道，烘房，老化房，高溫房等。特別適合于自動控溫和大流量高溫加熱器。風道式電加熱器使用的范圍寬：可以對任何氣體加熱，產(chǎn)生的熱空氣干燥無水份、不導電、不燃燒、不**、無化學腐蝕性、無污染、安全可靠、被加熱空間升溫快（可控）。<\/span> <\/span>
單臺功率從<\/span>2KW<\/span>～<\/span>500KW<\/span>系列。<\/span>
使用須知<\/span>Notice:<\/span>
控制方面，必須在風機與加熱器之間加一聯(lián)動裝置，以確保加熱器起動<\/span>,<\/span>需在風機起動工作之后進行。在加熱器停止工作后，風機必須延時工作<\/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>標準，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>
風道式加熱器的安裝形式包括：<\/span>
對接安裝，<\/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)實際情況，可以選擇各種合適的安裝方式<\/span>
風道加熱器因為其特殊性<\/span>
一般外殼材料采用碳鋼，或者不銹鋼、鍍鋅板<\/span>
而風道式電加熱器加熱部分大多采用不銹鋼材料，選用時，如材料碳鋼材料需要特殊說明。<\/span><\/span> <\/div>
