Alfa Laval have released the small metalworking coolant cleaning module named as the Alfie 500. The Alfie 500, available from Accessories for Manufacturing , is a mobile, plug-and-play system designed to remove contaminants from smaller metalworking systems. Based on high-speed centrifugal separation, it is dimensioned to handle volumes up to 1500 gallons (5 m3) operating either at standstill or during a production run, without interrupting the machining process.
The Alfie 500 separates tramp oil as well as metal fines and solid particles down to 1µm from the coolant. With top-ups, continuous cleaning extends the coolant lifetime to up to 10 times the life of oil without a centrifuge. This results in major savings on fluid and filter disposal and replacement. Clean production runs without breakdowns.
Clean coolants also result in precise machining coolants also extend tool lifetime and provide and fewer rejects. All functions are controlled by a PLC-based control system. Operating in bypass flow, the compact Alfie 500 can be installed in any metalworking system.
