The primary difference is the heat source. While others burn oil or gas, this model uses Electric Immersion Heaters. This eliminates the need for a burner, fuel storage, chimney, and air pollution control equipment.

Because there is no combustion of fossil fuels, there are no flue gases, soot, or CO₂ emissions at the point of use. This makes it the cleanest heating option available for modern factories.

Thermal fluid flows through a specially designed heating chamber containing high-grade electrical resistors. As the oil passes over these elements, it absorbs thermal energy and is then pumped to your equipment (reactors, stenters, etc.).

It is nearly 100% efficient. Since there are no exhaust gases or radiation losses through a chimney, every kilowatt of electricity consumed is converted directly into heat for your process.

Our standard electric units typically operate up to 300°C. However, custom-engineered models can reach 350°C using high-quality synthetic thermal fluids.

No. This is its greatest safety feature. Even at 300°C, the system operates at near-atmospheric pressure (typically just the pump discharge pressure), virtually eliminating the risk of pressure explosions.

We offer a wide range from 50,000 kcal/hr to 4,000,000 kcal/hr (equivalent to approximately 60 kW to 4600 kW).

We use Thyristor Power Controllers (SCR) or Solid State Relays (SSR) for modulating power. This allows for extremely precise temperature control, often within  ±1°C, which is superior to cycling fossil fuel burners.

• Low Flow Switch: Shuts off power if oil circulation stops to prevent element burnout.
• Over-Temperature Cut-off: Independent safety sensor to prevent oil "cracking."
• Expansion Tank Level Switch: Ensures the system has sufficient oil to operate safely.

The absence of soot and smoke allows for installation directly inside or near "Clean Rooms" without risk of contaminating the pharmaceutical products or sterile environment.

• Food Processing: For consistent, clean heat in ovens and fryers.
• Chemicals: For precise temperature control in sensitive reactions.
• Laminates & Plywood: For high-temperature pressing without the noise of a burner.
• Laboratories: Where space is limited and exhaust ducting is not possible.

Yes. Because it doesn't require a chimney or fuel tank, it has a very compact footprint and can be installed in basements or upper floors where a traditional boiler cannot go.

Generally, no. Since thermic fluid heaters are not steam-generating pressure vessels, they do not fall under the Indian Boiler Regulations (IBR). This saves you from annual government inspections and the need for a certified boiler attendant.

Maintenance is minimal compared to fuel-fired units:

• Periodically check electrical terminals for tightness.
• Inspect pump seals.
• Test the thermic fluid once every 6 months to ensure it hasn't oxidized.

With a "Low Heat Flux" design, our elements are built for longevity. Typically, they last 5 to 10 years provided the oil flow is consistently maintained and water is kept out of the system.

The price depends on the heating capacity (kW) and the pump flow rate. On indianboilers.com, current 2025 estimates are:

• Small units (up to 50,000 kcal/hr): Starting at approx ₹600,000.
• Mid-to-Large units (1 Lac to 5 Lac kcal/hr): Range between ₹10,00,000 and ₹45,00,000.
• High-capacity systems: Quoted on a custom basis depending on power requirements.

Per unit of energy, electricity can be higher. However, you save on:

• Zero fuel storage and handling costs.
• Zero burner maintenance.
• Zero cost for a chimney and pollution control.
• Reduced labor (no certified operator required).
