Direct Fired Makeup Air Heater

The products of combustion carbon dioxide co 2 carbon monoxide co nitrogen dioxide no 2 aliphatic aldehydes and water vapor are discharged into the makeup air stream and supplied to the building or process.

Direct fired makeup air heater.

And providing makeup air to factories and replacement air for exhaust hoods in restaurant kitchens. Direct fired make up air systems make up air heaters protect air quality for workers by improving indoor air quality with a dedicated outdoor air supply and filtration. This design results in an extremely efficient system that achieves 100 combustion efficiency and a 92 overall thermal efficiency with 8 of the total heat lost in the latent heat of water formed in combustion. In a direct fired make up air unit the air that is to be heated is passed directly over an open flame.

No heat exchanger is involved. Arizon s 100 outside air indirect or direct fired industrial air makeup units for heating and cooling are a perfect solution to negative building pressure problems as well as manufacturing and industrial buildings in need of large amounts of make up air with high process high exhaust issues such as paint booths welding facilities and other corrosive environments. Select from a variety of make up air units for commercial industrial and kitchen applications. The direct gas fired heater is etl listed for use in tempering make up air.

A natural gas or propane direct fired heater has an open flame that provides a safe way to heat industrial and commercial areas by maintaining a proper air to fuel ratio. Absolutaire has an absolute commitment to providing its customers with total value in direct fired make up air indirect fired make up air and heating and ventilating systems. Available cooling options are evaporative cooling direct expansion coils and chilled water coils. No venting or flue piping is required.

In a direct fired heater the gas is fed directly to the burner while the airstream provides the needed oxygen for combustion. Make up air direct fired heaters direct fired heaters deliver the most efficient tempered make up air for commercial and industrial applications requiring gas heat. With a good heat to air volume value they provide excellent temperature control with 25 1 modulation capability. A direct gas fired ahu has a gas burner installed directly in the outside makeup air stream.

Our direct fired systems are efficient and safe for many space heating applications. Building pressurization enhances warehouse comfort by reducing uncontrolled air infiltration near doors and dock areas. Heating options include direct gas fired indirect gas fired steam hot water and electric resistance. This means applying the best available technology to preserve precious resources slash heating and ventilation costs and shrink our environmental footprint.

Packages are certified to the current ansi z83 4 and csa 3 7 combined safety standard and are available in sizes up to 2 500 000 btuh and 21 000 cfm.
