Powerful hot-air roofing burners with totally encased flames for efficient bitumen laying when open flames are not permitted • Powerful enough to achieve the same speed of roof laying compared to open flames – and the gas consumption is much lower • The use of heat is very efficient due to the narrow and directed hot-air stream and due to the fact that one can work even closer to the material • All burners can use compressed air to increase power for welding and for quick and efficient drying • Working pressure 2 and 4 bar
