An Air Preheater (APH) is a device used to preheat the combustion air before it enters the Boiler furnace. At Dehu Engineering (India) Private Limited, we specialise in the design and manufacturing of High-Quality Air Preheaters for various industrial applications.

The primary function of an Air Preheater is to increase the efficiency of the Boiler by recovering heat from the flue gas that would otherwise be wasted. The preheated air is then used for combustion in the furnace, resulting in higher thermal efficiency and lower fuel consumption.

We take great pride in our commitment to quality and safety, ensuring that our Air Preheaters are designed and manufactured to the highest standards of performance and reliability. We also offer a comprehensive range of after-sales services, including Installation, Commissioning, and Maintenance, to ensure that our customers get the most out of their investment.
