Stand Alone Systems

There are several advantages to a stand alone coolant filtration system, the new trend and future in filtration systems. A stand alone system eliminates the need for large amounts of flushing, reduces piping and installation costs by 40% to 80%, reduces energy costs by 20% to 30%, eliminates the need for large pumpback systems, and reduces initial cost, in comparison to central systems, by 10% to 40%.

Central Systems

Barnes International supplies coolant filtration systems for large manufacturing facilities that filter aluminum and/or cast iron material from the coolant used in machining operations.

5,685 gpm Central Coolant Filtration System for V-8 and V-6 Engine Block Line. Includes primary drag conveyor, two (2) Barnes Kleenall Rotary Drum (RD) Filters, eight (8) Systems Pumps (1 Spare), Header, PLC Controller, automatic coolant make-up unit and accessory equipment. This system was later expanded to 11,495 gpm by the adding two (2) Rotary Drum Filters, eight (8) System Pumps, Header, PLC Controller and accessory equipment.

Controller and accessory equipment. Five (5) System Pumps and Header for 3,350 GPM Central Coolant Filtration System. PLC Controller starts pumps sequentially to prevent “water hammer” shock to return coolant piping system.

Pump Header Assembly

Typical Barnes in-floor dirty coolant flumes with clean coolant return pipes installed in pre-poured concrete trenches. A small portion of the clean coolant is used for flume flushing. Trench covers have been removed for this picture.

In the NNA facility, there are more than 1.7 miles of flume currently installed.
