Hot Air Generator


AIRPACK-SF(I) is a most super-efficient solid fuel fired hot air generator.


  • High Thermal Efficiency of 84-87% on NCV for indirect fired which gives large savings in fuel cost.
  • AIRPACK-SF(I) gives large savings in fuel cost as compared to hot air generation using Steam/Thermic Fluid based Radiators. This is due to elimination of heat transmission and steam condensation losses.
  • Low fly ash generation
  • Absolutely clean and ash / dust free process air of Pharmaceutical grade / Food grade is available.
  • Fully automatic mechanized fuel feeding system & combustion air control to ensure high thermal efficiency.
  • Controlled suspended particulate matter (SPM) levels in flue gas / process air
