Process Circulation heaters utilize the flanged or screw plug immersion heater bundle mated to a welded
pressurized pipe body or as we commonly refer to in our industry, the heater vessel. The circulation
heater can be mounted horizontally or vertically and piped in line with your process inlet and outlet
connections. The process air, liquid, or gas is force flowed from the inlet side of the heater
vessel over the metal sheathed nichrome resistive heating elements to the outlet side of the heater vessel.
This effectively allows 100% heat transfer efficiency from heater element to the process air, liquid or gas.
A temperature sensor is located at the heater outlet to measure process temperature and provide process
temperature feedback to the temperature control panel or plant control room. Circulation heaters are designed
and manufactured to be application specific depending on the design temperatures and pressures of the
process air, fluid or gas and the overall system parameters. Gaumer Process offers standard circulation
heater designs with or without insulation and well as customized circulation heaters to meet your
project specific application requirements.
