A Thermic Fluid Heater works by pumping a heat transfer fluid (thermal oil) which is particularly formulated in a closed circuit, transferring heat in the heater and imparting it to process equipment.
Working Principle
Liquid is suctioned from the expansion tank through heater or furnace coils, heated to the desired temperature (typically 200-350 °C or higher), and returned to provide heat to process units separately, to be reused again. Modern designs may include electronic control, sensing, and shutdown for safety (for example, flame detectors, flow switches, overheat protection) in a bid to make the system more reliable and efficient in energy use. It is one of the top Thermic Fluid Heater Indian suppliers who is offering the best quality Thermic Fluid Heater such as:
Types of Thermic Fluid Heaters
It is one of the top Thermic Fluid Heater Indian suppliers in India, whose every type of Thermic Fluid Heater is made with the latest technological formulation such as:
- Gas/Oil-Fired Thermic Fluid Heaters
These use a heavy oil, LPG, or natural gas burner to warm the thermal fluid. Low-NOx burners, modulation control, and online monitoring of the flue gas for regulatory requirements are offered on new equipment. They are applied in large capacities with high turndown and stable operation.
- Electric Thermic Fluid Heaters
Electric heaters are made of resistance heating that is submerged in heat fluid. They offer precise temperature control, no combustion gases, and are used in fuel-free locations. Developments involve SCR control for ramping smoothly and remote monitoring via IoT.
- Solid Fuel-Fired Thermic Fluid Heaters
These consume solid fuel, biomass, or coal outside of the furnace to heat the fluid. More sophisticated ones are equipped with automated fuel supply, ash cleaning, and emission management to reduce pollution and human contact. They could be used where solid fuel is economic or readily available.
- Waste Heat Recovery Thermic Fluid Systems
These systems recuperate waste heat from flue gas or exhaust streams to warm the thermal fluid. New designs include economizers, recuperators, or heat exchangers with intelligent bypass control. These increase plant global efficiency in the energy aspect by reducing fuel consumption.

Features of Thermic Fluid Heaters
- High thermal efficiency & low emission design
Our units have high-efficiency heat exchanger surfaces, low-heat-loss insulation, and burner modulation for fuel economy. They have flue gas recirculation and exhaust heat recovery to minimise emissions. Oxygen levels are monitored, and combustion is optimised continuously by the control systems.
- Advanced digital control & monitoring
All the heaters have a PLC/RDC interface, remote monitoring, and temperature, flow, pressure, and alarm data logging. Predictive analytics modules allow maintenance to be scheduled and fault detection. Real-time dashboards allow multiple units to be run from a single console.
- Solid safety & operational protection
We also provide flow switches, low-flow cut-off, over-temperature interlocks, pressure relief valves, and flame failure detection on all heaters. Latest models offer self-diagnostic software and auto-shutdown in fault scenarios. These protective devices protect equipment, fluid, and processes in an emergency situation.
- Compact modular & scalable design
Our four-pass, horizontally mounted, and vertically mounted modular heaters provide for site space or future capacity expansion. Simple on-site paralleling or adding is offered by new modular skids. Expansion of modules by our customers is done with little system disruption.
Benefits of our Thermic Fluid Heaters
| Benefit |
Description |
| Energy savings & operating cost reduction |
Effective combustion and heat recovery reduce the fuel use, keeping subsequent costs low. Intelligent control systems also avoid wastage by throttling according to need. Customers end up achieving a payback of 24 years across the entire product life. |
| Improved process stability & quality |
Constant availability of temperature (even under varying loads) gives close process parameter control. This translates to better quality product, less reject, and consistent production. Fast response and high-performance control prevent oscillations or overshoots. |
| Reduced emissions & compliance readiness |
New designs meet and exceed environment standards (e.g. for NOx, CO, particulate). Flue gas cleaners and emission analysers keep you within the law in dynamic regulatory regimes. Not only do this allow compliance with law, but corporate environmental reputation. |
| Low cost of ownership & long life |
Great materials, precise manufacture, and astute diagnostics maximise heater life and minimise down time. Predictive maintenance warnings prevent unexpected failure and conserve spare-part stock. |
Applications of our Thermic Fluid Heater
Being India's top-ranked Thermic Fluid Heater Exporters, our thermic fluid heaters come in all types of Thermic Fluid Heater are loaded with superior features and widely utilized in numerous applications including:
- Chemical, petrochemical & oil & gas plants process heat.
Thermic Fluid Heating Systems provide heat to petroleum refineries, distillation, evaporators, and reactors. Oil and Gas Fired Thermal Fluid Heaters and Gas Fired Thermic Fluid Heaters are common in these units. New heaters offer better temperature control with refining and remote monitoring to maintain safety and uniformity.
- Dyeing, textile & fabric finishing.
Textile factories use thermic fluid systems to provide heat to dryers, stenters, and finishing machinery. Thermic Fluid Heaters are fuelled electrically, or a horizontal thermic fluid heater can be used in smaller facility-based factories. The clean and consistent heat ensures fabric quality without energy wastage.
- Rubber, tyre & adhesive manufacturing.
Thermal operations like vulcanization, compounding, and curing involve proper heat control. Our heaters, like (e.g. 4-Pass Thermic Fluid Heater), ensure correct temperature uniformity between zones. Zonal control and feedback digital loops enhance product yield and consistency.
- Food, pharmaceutical & cosmetic industries.
Uses encompass indirect heating of thermal baths, dryers, sterilization, and distillation. Electric or gas/oil burners are chosen depending on site fuel availability and sanitation levels. Avoidance of direct combustion into product streams and tight controls ensure product safety and quality.
- Paper, pulp & board making
These installations have thermic fluid applied in deaeration units, calanders, and drying units. Horizontal Oil and Gas Fired Thermic Fluid Heater or Vertical Four Pass Thermic Fluid Heater models are suitable for paper units' large sizes. Waste-heat recovery models' installation also enhances energy efficiency in large plants.
- Heat treatment, annealing & industrial furnaces
Several heat-treating and metallurgical operations require stable heat baths. Our module gas heaters or our Solid Fuel Fired Thermic Fluid Heaters are suitable in mills where solid fuels are economically viable or where grid supply is expensive. Heat control to a high degree makes metallurgical properties even and uniform.
