Alumina ceramics lining
*1:
PFA is FDA (U.S. Food and Drug Administration)
approval material.
*2:
Natural soft rubber is a material which can reduce
wear of the lining due to fluids mixed with slurries. If
the concentration of mixed slurries is high, contact
Yokogawa as necessary measures need to be taken
separately for the electrodes.
*3:
EPDM rubber lining is superior in the ozone proof.
