Any of the fan-driven units can be modified to address specific particle sizes or service environments. “In some applications such as slag handling, the dust particles can be so small that they are more effectively managed with smaller droplets,” Stiverson observed. “In other situations, reduced flow may be preferred to protect moisture-sensitive materials.”
Three tower sizes are currently available. The 6“ base tube is generally employed on tower heights below 15 feet, and is compatible with the standard oscillation package. For greater elevation, 8“ diameter towers are used. The heavy-duty design is the 10“ diameter flange-mounted towers, which are secured directly into concrete. It is available in heights up to 20 feet with a range from 0-359°.
