Are there applications for which infrared heaters are NOT suitable?
You may not use gas-fired infrared heaters inside paint booths or in buildings where explosion-proof lights are required. Although infrared is not ideal as an air curtain, it is very effective in spot-heating work areas inside of doorways, in dock areas and on outdoor docks. In dusty/woodworking environments, we recommend that outside combustion aire must be directly supplied to the control box.
