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.
循环加热器由一个绝缘管体组成, 其中包含螺旋塞加热器或法兰浸入式加热器组件。它们的设计目的是通过在单一的通行证或重新循环, 多通系统的容器中加热空气, 气体或液体。这些设备可以水平或垂直安装, 可用于各种管道螺纹和法兰入口和出口选项。终端外壳可用于室内、室外 (防风化 nema 4) 和危险 (nema 7) 环境。有许多选项可供选择, 包括恒温器、高限制和过程热电偶或 RTD 传感器。
