An internationally known organization was looking for a better way to filter hot gases from an incinerator that destroyed obsolete munitions. Their existing dust control system required the gas stream to be cooled to below 500? F so it could run through a conventional baghouse with fabric filters. This cooling process plugged the aftercooler on a regular basis and created a maintenance nightmare. The customer wanted to eliminate the aftercooler – with its high maintenance costs and downtime – and also reduce metal emissions.  It was critical that the new system filter hot gases up to 1000? F and do so continuously year-round with minimal maintenance shutdowns.

Griffin engineers, with over 40 years of experience solving tough dust control problems, were up for the challenge. The Nova series was developed to address these difficult conditions. One of the primary concerns was to design a unit that would expand and contract with the temperature changes without causing leakage or fatigue.
