Small Industrial Boilers (SIB)
Small Industrial Boilers (SIB) are compact and easy-to-operate steam boilers designed for small-scale process industries. Our SIB model features a horseshoe design with an external furnace, for good combustion efficiency and simplified maintenance. From the boiler furnace, flue gases pass through a series of tubes with the three pass tube design ensuring uniform heat distribution and maximum heat recovery. The external furnace allows efficient fuel burning and better control over flue gas temperature, resulting in high thermal efficiency and overall performance. These boilers are built to deliver reliable steam generation while complying with safety standards. Their robust construction and user-friendly design make them a preferred choice for small industrial applications.
As per the Indian Boilers Regulations , a Small Industrial Boiler (SIB) is a boiler which has a maximum water holding capacity of less than 500 liters and the operating pressure is less than 7 kg/cm² (g). They have a simplified design, inspection, and certification procedures compared to larger IBR boilers, ensuring safety and efficiency while allowing faster installation, easier maintenance, and compliance with national regulatory standards.

Coil fired boiler related FAQ's
A small industrial boiler refers to a steam boiler designed for lower capacities, compact size and ease of installation. In India, under the Indian Boilers Regulations, a boiler with water-holding capacity less than 500 litres and operating pressure below 7 kg/cm²(g) is classified as a small industrial boiler.
Our SIB model covers capacities from 100 kg/hr to 700 kg/hr, ideal for small to mid-scale process industries.
The SIB offers multiple fuel options: light oil, heavy oil, PNG (natural gas), LPG and biogas, providing flexibility based on your fuel availability and cost considerations.
Industries such as pharmaceuticals, garments, food processing, rubber, laundry and other small-scale production plants will find SIB a suitable solution for their steam requirements.
The key features include an external furnace (horseshoe design) for efficient combustion, a three-pass tube arrangement for uniform heat distribution, high thermal efficiency and ease of maintenance.
While exact footprint depends on capacity and configuration, the SIB’s compact design uses significantly less floor space compared to larger IBR-boilers, making it ideal for plants with limited room.
Fuel cost is a major part of operating expenses. Depending on fuel availability and price dynamics (oil vs gas vs biogas), you should select the most economical fuel option and ensure efficient combustion for lower fuel cost per kg of steam.
Yes. While SIB is designed for current small-scale operations, depending on your future demand growth you can select capacities closer to the upper range or plan for modular expansion.
Key maintenance tasks include routine water-treatment to avoid scaling, blowdown to remove impurities, inspection of tubes and burner, and ensuring combustion is optimised — all help maintain steam boiler efficiency.
