Mist Collection systems

“Rohde Brothers, Inc. worked closely with me to develop a hooded capture system that allowed filtered air to be returned to the factory space.

Mist Collection Hood and Equipment
The Rohde Customized Solution:
  • Design, fabrication and installation of die lube over spray and shot fume capture and treatment systems for eachdie cast machine with retractable hood, multistage filters and fan with return of treated air back into the plant

  • Retractable hood allows for die changes using overhead crane

  • Four stage filtration systemremoves die lube/water mist, smoke, oil and particulates allowing return of treated air to the plant significantly reducing the volume of makeup air required

  • Variable speed makeup air and exhaust fans added for each die cast machine

  • Custom PLC for monitoring and controlof the mist collection system provided by Rohde and integrated into Mercury’s central ignition system

  • Redesign of the capture hood system and piping systems to accommodate the larger 4500 ton capacity of the third die cast machine. In addition to the larger size, the plant elected to make multiple changes in the methods employed for die preheating and cooling for process quality and efficiency improvement. The new capture system support structure incorporated an equipment platform for new heating and cooling equipment

  • Based on the success of the first three mist collection systems, Rohde has installed additional systems in the original plant and a subsequent 2019 addition

  • To date, a total of ten mist collection systems have been installed
