Equipment Details

Limestone Feeder

The Oil Guardian™ is a limestone feeding unit that continuously doses limestone powder into the fume control system ductwork. Oil Guardian™ features three agitators that supply a steady uninterrupted flow of limestone powder from the hopper to the duct.

The Oil Guardian™ is to be installed between the Spark Guardian™ and a sliding valve. The limestone decreases the combustibility of oil in the system. The mixed limestone and oil become a dry matter. When it
reaches the filter, the dry matter falls down in the dustbin during the cleaning cycle.

 

APPLICATIONS:

Oil Guardian™ is part of Lincoln Electric’s GUARDIAN™ fire safety solutions for fume control systems and is recommended for applications with an increased fire risk, such as:

  • Robotic welding of oily stamped products
  • Robotic and automatic welding of oily products
  • Manual welding of oily products
  • Cutting tables
  • Schools/Other areas with risk of cigarette butts
