The Alfa Laval AlfaPure S7 is designed to clean water-based cutting and wash fluids in metal- working processes in light industries, vehicle manufacturing, aerospace, aluminum can and general manufacturing. The cleaning achieved using high-speed centrifugal separation greatly extends the lifetime of the service fluids. The result is lower costs due to reduced service fluid consumption, lower costs for disposal of used fluids, oil and filters, more plant uptime, and improvements in both product quality and working environment. The system removes tramp oil, grease and solid particles from water-based coolants and wash liquids.
