What Is a Circulation In-Line Heater?
A circulation in-line heater is a heavy-duty flow-through electric heater designed to heat liquids and gases directly in process piping. Unlike immersion heaters that are submerged in tanks, circulation heaters are installed in-line, allowing the process fluid to flow through the heater body where it comes into direct contact with heating elements. This design provides rapid heat transfer, precise temperature control, and minimal pressure drop in continuous flow applications.
INDEECO circulation heaters feature a heavy-duty pressure vessel containing multiple heating elements specifically designed for the required wattage and temperature rise. As fluid circulates through the vessel, heat is transferred efficiently from the elements to the process medium. The compact in-line design eliminates the need for separate heating tanks and integrates seamlessly into existing piping systems. Multiple heating stages with staggered control allow for modulated power output, enabling precise temperature maintenance without hot spots or thermal shock.
These heaters excel in applications requiring continuous temperature maintenance, rapid heating, or preheating of process fluids. Common uses include maintaining oil temperature in pipelines, heating chemical feeds before reactors, preheating fuel oils for combustion systems, boosting steam temperature in process lines, and heating water for industrial cleaning systems. ZIRCO provides expert application support for Western Canada industries, helping you select the right circulation heater configuration for your specific process requirements including flow rate, temperature rise, fluid properties, and electrical characteristics.
