Alfa Laval AlfaPure S2
High speed centrifugal separation system for cleaning coolants, wash liquids, and mineral oils
Application
The Alfa Laval AlfaPure S2 is designed to clean service fluids
in metal- working processes in industries, such as vehicle
manufacturing (tier suppliers), and light industries, such as
white goods, a erospace, metal components, and can manu-
facturing. The level of cleaning efficiency 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
oil and filters, more plant uptime, and improvements in both
product quality and working environment.
The AlfaPure S2 is available in concentrator, clarifier and
purifier versions. Configured as a concentrator, the system
removes tramp oil, grease and solid particles from water
based coolants and wash liquids. The clarifier is a two-phase
version where fine solids are removed from water-based
coolants or wash liquids. The purifier version of AlfaPure S2
is for cleaning of mineral oils, removing water and fine solids,
thus preventing wear, corrosion and breakdowns.
Design
AlfaPure S2 is a complete plug-and-play system c omprising Due to their high speed, disc stack technology, and a utomatic
