What is Air Heater?
An Air Heater is a specially designed heat exchanger system that is employed to exchange the thermal energy of a hot medium and a cold medium that is ambient or process air. The main purpose is to preheat the burn air entering a boiler or furnace, or to supply hot air to all manner of industrial processes such as drying, curing or space heating.
How our Air Heater works?
Hot Source Stream: This is a stream of hot liquid that typically enters one side of the air heater, typically high-temperature flue gas of an industry or combustion exhaust.
Cold Air Intake: The ambient or process air is pulled into the air heater at the same time and passes through different passages or surfaces so that it does not mix with the hot stream.
Mechanism of Heat Transfer: The heat on the hot flue gases is conducted to a dividing surface to the cooler air stream without any physical contact.
Cooler Exhaust Discharge: The initial flue gas stream is discharged as the original hot flue gas stream but at a lower temperature and this allows easy emissions control and heat recovery.
Why choose us as best Air Heater manufacturers in India?
Custom Design and Engineering: Our products are not generic; each air heater is carefully engineered to fit within the space and thermal needs of the particular plant of the client.
Strong Building Quality and Strength: We use superior quality and tough materials and use strict manufacturing conditions, so the units of our product withstand high temperatures and long-term use in industry.
Past Incident of Energy Saving: Our air heaters are known to be designed with maximum heat recovery, which continually makes them provide fuel efficiency and minimize operating costs.
Duct Heaters: A continuous stream of flowing gas is heated by entering the heater.
Forced Air Heaters: A forced air heater is where the air is blown or blown by the use of a fan or blower over a heating device and distributed.
Radiators: The heat is produced by heating a fluid circulating in coils, and the air is heated by passing it over the coils.
Tubular Heaters: Have a flexible heating element which is customizable.
Enclosure Heaters: These are used to provide temperature and humidity control in a certain enclosure.
Space and Room Heaters: Portable heaters that are used to heat one room, and they may have features such as tip-over switches and cool-touch surfaces.
By Heat Source or Method
Direct Heaters: This is where the end product is directly heated using combustion products without any medium in between Air Heater suppliers in India.
Indirect Heaters: Radiators indirectly pass heat produced during the combustion process to the air using a metal pipe or other heat exchanger.
Regenerative Heaters: A rotating matrix is used which periodically receives the heat of the hot flue gas and consequently transfers this heat to the entering air.

Benefits of selecting us as Air Heater suppliers in India
We as Air Heater suppliers in India, we provided different benefits according to atmosphere which are given below.
Improves Boiler Efficiency: With preheated combustion air, less fuel energy is used to heat up the flame raising the thermal efficiency of the system directly for Electric Air Heater.
Lessons Fuel Consumption: The overall use of the waste heat that goes to waste because of the stack causes a significant and quantifiable reduction in the total amount of fuel used in the process for Air Heater manufacturers in India.
Increases Quality of Combustion: The hotter air is used in combustion, the more complete and stable combustion process is achieved, and this assists in minimizing the creation of the harmful pollutants such as carbon monoxide.
Enhances Drying Rate in Processes: The consistent provision of hot and dry air accelerates industrial drying, curing or baking processes and, as such, raises production throughput and cycle times.
Prolongs Equipment Life: The air heater saves high-temperature exhaust heat, which can damage down-stream equipment, including induced draft fans for Air Heater dealers in India.
