Screw Plug Heaters are constructed by brazing or welding elements into a hex pipe thread. These are intended for direct immersion into fluids and gases. The heater is to be installed via a threaded port in the tank or vessel. Screw plug heaters are available in a variety of pipe thread sizes and materials. The heating elements are offered in a number of materials suited to a variety of fluid heating applications. Terminal housings are available for indoor, outdoor (weather- proof NEMA 4) and hazardous (NEMA 7) environments. Many options are available including thermostats, high limit and process thermocouples or RTD sensors. Since we are a made to order company, we can offer a large selection of sizes and configurations which are not listed below. Please contact us for assistance with your application.
螺旋塞加熱器是由釬焊或焊接元件制成的六角管螺紋。它們的目的是直接浸入液體和氣體中。加熱器將通過坦克或容器中的螺紋端口安裝。螺桿式加熱器可在各種管道螺紋尺寸和材料中使用。加熱元件提供了一些適合各種流體加熱應(yīng)用的材料。終端外殼可用于室內(nèi)、室外 (防風(fēng)化 nema 4) 和危險(xiǎn) (nema 7) 環(huán)境。有許多選項(xiàng)可供選擇, 包括恒溫器、高限制和過程熱電偶或 RTD 傳感器。由于我們是一家訂購(gòu)的公司, 我們可以提供大的選擇大小和配置, 沒有列出如下。請(qǐng)與我們聯(lián)系, 以協(xié)助您的申請(qǐng)。
