Ring electrode system
AFA 25-105 series liquid resistance starters are based on the original 1917 design produced by BEA. Their production and further development was taken up by MKS in 2001. These liquid resistance starters incorporate the classic BEA ring electrode system.
MKS liquid resistance starters stand out for their high current rating and power range. They have a high resistance ratio and a very low final resistance at their minimal electrolyte concentration.
These liquid resistance starters are rated from 2,000 to 20,000kW. The excellent characteristics of these liquid resistance starters for the starting of slip ring motors can be employed in nearly all drive systems where high levels of starting torque are required and/or where poor network conditions are present. They are often used for the starting of mills, ventilators, pumps and crushers but also in more unusual applications, such as in sugar mills.
