We have developed our ARGOS burner series especially for direct fresh air heating. The special design enables operation either with or without a combustion air fan. The choice is yours - the concept opens up a wide range of possible applications. The ARGOS series can be used with various fuel gases: natural gas, liquid gas or biogases are possible. Operation is possible in negative pressure, back pressure or alternating pressures. Possible applications include fresh air heating for paint booths, drying for painting and coating as well as thermal and catalytic systems. The burner is characterized by optimized heat distribution within the air duct.
