Low-Temperature Direct & Indirect Drying

World-class combustion technology to power low-temperature dryers

Fives designs and supplies advanced combustion products for low-temperature process heating. Our burners have broad applications for direct and indirect drying across a range of industries, including:

  • Printing and converting

  • Powder coating

  • Food roasting

  • Automatic coating

  • Textiles

Our ITAS Ductflame, ITAS Dryflame, North American ZephyrTM and North American Magna-FlameTM burners are low-emissions, high-efficiency installations with a range of low-temperature applications.

Plug & play burners for ovens, steam producing heaters, dryers and fume incinerators

Fives offers a wide range of heating systems to power the production and drying of paper and ceramics. Our burners can reuse process air from steam-producing heaters and recover air from ovens.

ITAS Ductflame duct burners are ideal for low-temperature drying applications that require warm, clean air production on a large scale.

These modular duct burners are available in F/L/R and H/T/C models ranging from 100 kW to 30 MW. Their highly flexible plug-and-play technology is characterized by:

  • Mixture formation on the flame head
  • Combustion air sent into the burner via a ventilator
  • Controlled air gas mixer for greater efficiency
  • Mixing on nozzle outlets to avoid back firing
  • Operability even when treated air is not constant and/or with low oxygen content

Nozzle mix burners for food, ceramics, paper, painting, coating and general drying

Nozzle mix packaged burners are reliable and efficient installations for food, feed and dairy, as well as ceramics, paper, painting, automotive coating and general drying. Our integral fan nozzle mix burner technology is ultra-stable, operating at 20% excess air, at up to 1,093°C (2,000°F) under negative or slightly positive pressure. 

The ITAS Dryflame is the latest generation nozzle mix compact corner burner. Available from 300 to 800 kW, this packaged burner operates with natural gas, liquefied petroleum gas (LPG) and biogas.

The ITAS Hot Air Generator HF can be used with the ITAS Dryflame for any application where the process air stream and burner flue gases are separate. It can power production for automotive, food, metals, ceramics and pharmaceutical processes requiring hot air recirculation.

Fives’ ITAS product line for low-temperature applications also includes:
