HOT AIR GENERATOR (HAG)

A fully automatic hot air generator consists of stainless steel shell type integral
combustion chamber accommodated in multi M.S. shell. A suitable capacity
blower fan is used in first pass to insert cold air. Cold air absorbs heat from flue
gas passage and accordingly both hot flue gas and cold air travel in opposite
direction in the passage which ultimately transfers 90% heat to cold air and
delivers hot air from hot air outlet hole. The temperature sensing device, installed
at hot air outlet which ON-OFF the burner at pre-set temperature assists the

system to function fully automatic. The system is a package type unit, fixed on
common base frame.

Application:

•  A HAG is used to keep the power equipment inner parts dry from moisture.
•  Sufficient oxygen supply will be there for the maintenance staff while working inside the equipment.
• It is more reliable, economic, convenient and safer than nitrogen.
