Pyrotek | Electromagnetic Deep Filtration (EM-DF) System | Narration

The EM-DF is a ceramic foam filter (CFF) box used for filtering molten aluminium. It uses electromagnetic coils to prime the metal through a stack of CFFs. This is currently the only technology available on the market that can prime three CFFs at a time. It is also the only technology that is engineered with a tool for loading and removing filter stacks.

Full priming of single and multiple CFFs
Controlled priming via electromotive/Lorentz forces, dynamic metal velocity, and static metal head
Standard filter box design with slightly deeper box and induction coils
EM field applied only during the priming and draining stage
Filtration operation on fully primed CFFs guarantees: 1) consistent filtration efficiency, 2) stable operation, 3) reliable performance
The patented lifting tool is used to insert, locate and remove the filter stack
Benefits
Able to prime multiple CFFs of different grades
Reduced metal head height for priming compared to that required for a typical gravity head priming process
Lower running costs and greater flexibility than a typical DBF system
Able to drain a portion of the entrapped metal from the CFFs upon completion of the cast
Able to provide high degree of automation
Proven repeated operation in a production environment
Less risk of failed casts due to floating/unprimed CFFs
Easy to operate and low maintenance

Lifting Tool
*Makes automation possible
*Greatly improves operator safety
Reduces the amount of filter debris that needs to be removed since filters are removed as one stack
