Circulation Heaters consist of an insulated pipe body containing a Screw Plug Heater or Flanged Immersion Heater assembly. They are designed to heat moving air, gases or liquids through the vessel in a single pass or re-circulating, multi-pass system. These units can be mounted horizontally or vertically and are available with a variety of pipe thread and flanged inlet and outlet options. 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.
循環加熱器由一個絕緣管體組成, 其中包含螺旋塞加熱器或法蘭浸入式加熱器組件。它們的設計目的是通過在單一的通行證或重新循環, 多通系統的容器中加熱空氣, 氣體或液體。這些設備可以水平或垂直安裝, 可用于各種管道螺紋和法蘭入口和出口選項。終端外殼可用于室內、室外 (防風化 nema 4) 和危險 (nema 7) 環境。有許多選項可供選擇, 包括恒溫器、高限制和過程熱電偶或 RTD 傳感器。
