Hot Water Boilers

NJS Series

We manufacture a range of Hot Water Generators (HWG) designed for industries and facilities requiring controlled hot water for process heating, cleaning, space heating, and other thermal applications. Engineered for fuel efficiency and long-term reliability, our hot water boilers are ideal for low-pressure heat transfer where steam is not necessary. Our custom-built hot water boilers are crafted for consistent performance across diverse operating conditions — from small-scale commercial facilities to specialized process industries. Ideal for textile processing, hotels, food production, pharma, cleaning systems, and HVAC.

For temperatures up to 160°C

Available in vertical and horizontal boiler formats

Fuel options available are Solid, Oil & Gas

Available in Pressurized and Non-Pressurized Systems

Lower operating cost than steam systems for certain applications

Heat Recovery Units

Our Heat Recovery Systems are designed to improve energy efficiency and reduce fuel consumption in industrial steam and hot water applications. By capturing waste heat from exiting flue gases or residual condensate, these systems preheat boiler inputs — significantly reducing the energy needed to bring them up to operating temperature. By recovering this heat and reusing it, our HRUs help industries lower operational costs, improve boiler efficiency, and reduce carbon emissions, making them a critical component of sustainable steam system design.

Whether you’re upgrading an existing boiler system or designing a new energy-efficient setup, our Heat Recovery Units offer a reliable and cost-effective solution for optimizing thermal resources.

Air Preheaters (APH)

Our Air Preheaters recover heat from flue gas exhaust and use it to preheat ambient air before it enters the combustion chamber. This improves combustion efficiency, reduces fuel consumption, and lowers flue gas temperatures — ensuring better overall thermal performance.

Water Preheaters (WPH)

Our Water Preheaters use hot flue gases to preheat feedwater before it enters the boiler. By increasing feedwater temperature, the boiler requires less fuel to convert water into steam, enhancing operational efficiency and reducing start-up times.

Condensate Heat Recovery Systems

Our Condensate Heat Recovery Systems capture residual heat from returned condensate after it exits process equipment. This hot water is then fed back into the boiler feed system, reducing the energy required to raise feedwater temperature from ambient levels.

Industrial Air Purification Systems

Our range of air purification and pollution control systems are designed to help industries meet government-mandated emission norms while minimizing the environmental impact of boiler and process exhaust. Engineered for durability and efficiency, these systems ensure the safe and effective removal of particulate matter, dust, and pollutants before they are released into the atmosphere.

With increasing focus on clean air mandates and ESG compliance, our pollution control equipment supports industries in becoming cleaner, more responsible, and regulation-ready — without compromising on performance.
