If your plant runs on a Thermopac (thermic fluid heater), you already know one thing: it never fails at a convenient time. A dip in heat transfer oil temperature, a burner that won’t fire cleanly, or an unplanned shutdown during a production run can cost lakhs in a single shift. That’s exactly why more industrial plants across India are moving away from in-house, part-time supervision and hiring a dedicated Thermopac Operational Contractor in India.
We operate, maintain, and support Thermopac and thermic fluid heater systems for manufacturing units, food processing plants, textile mills, chemical plants, paper mills, pharmaceutical facilities, steel plants, and power plants across the country. Our engineers manage everything from daily operation and combustion tuning to preventive maintenance, emergency breakdown response, and annual maintenance contracts (AMC) so your heating system runs safely, efficiently, and without surprises.
This page walks you through what a Thermopac system actually does, what a professional operational contractor handles day to day, and why outsourcing this function is quickly becoming the industry standard in India.
What is a Thermopac System?
A Thermopac — also called a thermic fluid heater or hot oil heater — is an industrial heating system that circulates heat transfer oil (thermic fluid) instead of steam to deliver process heat. The fluid is heated in a closed-loop furnace and pumped through the plant at low pressure but high temperature, which makes it safer and more energy-efficient than a comparable steam boiler for many industrial applications.
A typical Thermopac system includes:
- Combustion system and burner – generates controlled heat using coal, wood, briquettes, agro-waste, furnace oil, diesel, or natural gas
- Heat transfer oil (thermic fluid) – carries heat through the circuit instead of steam or water
- Oil circulation pump – keeps thermic fluid moving through the coil and process lines
- FD fan (Forced Draft) and ID fan (Induced Draft) – manage air supply and flue gas extraction for combustion
- Expansion tank – absorbs the thermal expansion of the oil and maintains system pressure
- Fuel pump and fuel handling system – feeds fuel to the burner at a controlled rate
- Temperature controller and pressure monitoring instruments – regulate outlet temperature and flag abnormal readings
- Industrial furnace/combustion chamber – where fuel is burned to heat the circulating oil
Because Thermopac systems run at low pressure and high temperature (typically up to 300–350°C), they’re widely preferred over steam boilers in industries where uniform, high-temperature process heat is required without the pressure-vessel risks of steam.
What is a Thermopac Operational Contractor?
A Thermopac Operational Contractor is a specialist engineering service provider who takes full responsibility for running and maintaining a plant’s Thermopac system — instead of the plant relying on its own, often under-trained, in-house staff.
In practice, that means we supply trained Thermopac operators, boiler attendants, and maintenance engineers who manage:
- Daily start-up, shutdown, and round-the-clock operation
- Fuel management and combustion efficiency
- Preventive and breakdown maintenance
- Safety inspections and compliance checks
- Spare parts coordination and repairs
- Documentation, logbooks, and performance reporting
Rather than hiring, training, and retaining your own Thermopac crew, you get a ready, accountable, and experienced team — a Thermopac O&M (Operation & Maintenance) contract — under a single service agreement. This is the model most manufacturing and process industries across India are now adopting for their Thermopac operations.

Our Thermopac Operation & Maintenance Services
We offer complete, end-to-end Thermopac O&M — you can engage us for a single service or a full annual contract that covers everything below.
Thermopac Commissioning
New installations and system upgrades need careful commissioning to avoid early-life failures. Our team handles pre-commissioning checks, oil filling and flushing, burner tuning, control loop testing, and a supervised trial run before handover — so your Thermopac starts its operating life correctly calibrated, not “fixed” six months in.
Thermopac Shutdown Services
Planned shutdowns — whether annual, seasonal, or for a plant-wide maintenance window — need a defined sequence to avoid thermal shock and oil degradation. We manage safe cooldown, internal inspection, coil descaling where required, and documented restart readiness, so your shutdown becomes a maintenance opportunity instead of a risk window.
Fuel Management
Whether you run on coal, briquettes, agro-waste, furnace oil, diesel, or gas, fuel handling directly affects combustion efficiency and operating cost. We manage fuel quality checks, storage practices, and consumption tracking to reduce wastage and stabilize your fuel-to-heat output ratio.
Combustion Optimization
Poor combustion tuning is one of the biggest silent cost-drivers in Thermopac operation. Our engineers regularly check air-fuel ratio, flue gas temperature, and excess air levels, and retune the burner and FD/ID fan settings to keep combustion efficiency high and fuel bills predictable.
Heat Efficiency Improvement
We identify heat loss points — insulation gaps, scaling inside coils, poor oil circulation — and recommend or execute corrective work that restores your system closer to its design efficiency, directly reducing fuel consumption per unit of process heat delivered.
Preventive Maintenance
Scheduled inspection and servicing — oil quality testing, pump and valve checks, instrument calibration, coil inspection — catch small issues before they become breakdowns. This is the single biggest lever for reducing unplanned downtime on a Thermopac system.
Breakdown Maintenance
When something does fail, response speed matters. Our team diagnoses and repairs burner faults, pump failures, control system issues, and leaks, working to restore operation with minimum production disruption.
Safety Inspection
We conduct regular safety checks on pressure relief systems, expansion tank levels, flame safety controls, and electrical interlocks, in line with industrial safety norms — reducing risk to both equipment and personnel.
Boiler Room Management
Beyond the Thermopac unit itself, we manage overall boiler/Thermopac room housekeeping, log maintenance, shift handovers, and operator discipline — the operational basics that most breakdowns actually trace back to.
Emission Control Support
We support flue gas monitoring and combustion adjustments that help plants stay within pollution control board emission norms, and coordinate with your compliance team for statutory inspections.
Energy Saving Solutions
From waste heat recovery opportunities to insulation upgrades and combustion tuning, we help identify practical, ROI-backed energy efficiency improvements specific to your Thermopac setup.
24×7 Operational Support
Thermopac systems in continuous-process industries can’t wait for “business hours” support. We provide round-the-clock operator coverage and on-call breakdown response for plants that run 24×7.
AMC Services
Our Thermopac AMC (Annual Maintenance Contract) bundles scheduled preventive maintenance, priority breakdown response, spare parts coordination, and safety inspections into a single predictable annual cost — removing the guesswork from your maintenance budgeting.
Emergency Support
For unplanned Thermopac failures, our emergency response team is available for rapid diagnosis and repair to minimize production loss, backed by our understanding of common failure patterns across fuel types and system ages.

Frequently Asked Questions
1. What does a Thermopac Operational Contractor actually do? A Thermopac Operational Contractor manages the day-to-day running of your thermic fluid heater — operation, fuel management, combustion tuning, preventive maintenance, breakdown repairs, and safety compliance — under a service agreement, instead of your plant handling it with in-house staff.
2. How is a Thermopac different from a steam boiler? A Thermopac heats and circulates thermic fluid (heat transfer oil) at low pressure, while a steam boiler generates steam at high pressure. Thermopac systems are generally considered safer for high-temperature process heating and are common in textile, food, and chemical applications.
3. Why should I outsource Thermopac operation instead of using in-house staff? Outsourcing gives you trained, specialist operators, structured preventive maintenance, faster breakdown response, and predictable AMC costs — without the overhead of recruiting and training your own dedicated Thermopac crew.
4. What is included in a Thermopac AMC? A typical AMC includes scheduled preventive maintenance visits, priority breakdown response, safety inspections, combustion checks, and documented reporting, bundled into a fixed annual cost.
5. Do you provide 24×7 Thermopac operators? Yes. For continuous-process plants, we can deploy round-the-clock operator coverage along with on-call emergency breakdown support.
6. Which industries use Thermopac systems the most? Manufacturing, food processing, textile, chemical, paper, pharmaceutical, steel, and power industries are the most common users of Thermopac systems in India.
7. What fuels can a Thermopac system run on? Common fuels include coal, wood, briquettes, agro-waste, furnace oil, diesel, and natural gas, depending on the burner design and plant location.
8. How often should preventive maintenance be done on a Thermopac system? Frequency depends on usage intensity and fuel type, but most continuous-process plants benefit from monthly operational checks and a more detailed quarterly or half-yearly maintenance cycle, alongside daily operator checks.
9. What causes most Thermopac breakdowns? Common causes include poor combustion tuning, oil quality degradation, pump or valve failure, scaling inside coils, and inconsistent preventive maintenance — most of which are preventable with disciplined O&M practices.
10. Can you handle both commissioning and ongoing maintenance? Yes. We handle new system commissioning, planned shutdowns, and ongoing preventive and breakdown maintenance, so you can engage us at any stage of your Thermopac’s lifecycle.
11. Do you help with pollution control compliance? We support flue gas monitoring and combustion adjustments that help keep emissions within regulatory norms, and assist with documentation for statutory inspections.
12. How quickly can you respond to a Thermopac breakdown? Response time depends on your contract terms and location; AMC clients typically receive priority response commitments defined at the time of agreement.
13. What is combustion optimization and why does it matter? Combustion optimization means tuning the air-fuel ratio and burner settings for maximum heat output per unit of fuel. Poorly tuned combustion is one of the biggest hidden causes of high fuel bills in Thermopac operation.
14. Do you supply Thermopac spare parts as well? Yes, through our associated supply operations we help coordinate genuine spare parts, reducing delays during repairs and maintenance.
15. Is a Thermopac operational contract only for large plants? No. Small and mid-sized manufacturing units benefit significantly from outsourced Thermopac operation, since it removes the burden of hiring specialist staff for a single piece of equipment.
16. What documentation do you provide during a service contract? We maintain operational logbooks, maintenance records, and periodic performance reports so you have a clear compliance and efficiency trail.
17. Can I start with a single service before signing a full AMC? Yes. Many clients begin with a system audit, commissioning support, or a one-time breakdown repair before moving to a full annual O&M contract.
