Direct Hot Air Generator

  1. DHAG systems replaces conventional, expensive fuel like LPG, LDO, FO, NG firing in baking, polymerizing, curing, drying, etc processes.

  2. These systems can give hot air to the process upto 700°C and 1crore Kcal/hr .

  3. The temperature accuracy of fully automated DHAG system is ±2°C.

  4. These systems can be operated on any of the low cost solid fuel available locally where some amount of dust/ash particles are allowed for process requirement.



THE DIRECT (FBC) HOT AIR GENERATOR CONSISTS:
