                                  GENERAL INFORMATION
 Continuous Weld
 > Weld locations vary            A regenerative thermal oxidizer (RTO) is an industrial process that
 > See engineering standard E1-14  destroys  air  pollutants  emitted  from  process  exhaust.  These  gas
                                  streams are usually produced by industrial process ventilation, i.e.
 Seal Weld                        paint booths, printing, and paper mills. Fans are tested at the shop
 > Weld locations vary            with a Soap Bubble Test to check for leaks.
