Circulation Heaters
Industrial heaters are critical components in process heating systems, designed to transfer thermal energy to liquids, gases, solids, or surfaces across a wide range of industries—from oil & gas to food processing, chemical, pharmaceutical, and power generation. At Integro Process Heating Solutions, we design and manufacture robust, energy-efficient heaters engineered to meet stringent thermal, mechanical, and safety requirements.
Integro circulation heaters heat liquids and gases as they flow through a fully enclosed, insulated vessel fitted with immersion heating elements. Fluid enters, passes over the elements and exits at the required temperature — an efficient, compact solution for continuous inline heating of water, thermal oils, fuels, gases and chemicals.
Each heater is custom-engineered for your medium, flow rate, inlet/outlet temperature, pressure and material of construction (SS304/SS316 and specialty alloys), with digital thermostats, controls and safety cut-offs. Rugged, energy-efficient and built to code for pharma, chemical, oil & gas, and general process duty.
Looking for a different heating method? Our immersion heaters for tanks and vessels submerge directly into the process fluid for faster, more localized heat transfer, while our electric air heaters and duct heaters are built for heating air streams and enclosed spaces rather than liquids.
Circulation heaters are typically specified wherever a process needs continuous, closed-loop heating rather than open-tank immersion — hot-oil skids, glycol and water loops, fuel-gas conditioning, and CIP (clean-in-place) circuits are common examples. We size the heater to your flow rate and watt density to avoid hot-spot fouling, and can supply ASME- or CE-rated pressure vessels where the application demands it.

Q. What is a circulation heater?
A. An enclosed inline heater with immersion elements through which a fluid flows and is heated to a set outlet temperature.
Q. What fluids can it heat?
A. Water, thermal oils, fuels, gases and many chemicals — matched to your medium.
Q. How is a circulation heater sized?
A. Sizing is based on flow rate, inlet/outlet temperature, pressure and fluid properties.
Q. What materials are available?
A. Common options are SS304 and SS316, with specialty alloys available.
