For the metalworking industry, coolants are a major expense.

Some are obvious: Replacing them – a messy and time-

consuming task. Disposing of them – a continually rising

expense in the face of today’s environmental regulations.

But dirty coolants also incur other less obvious but no less

expensive costs. For example, tramp oil and solid particles

in coolants can cause increased tool wear, quality problems

during later processing and health problems for your

personnel.

In short, it’s well worth the effort to take steps to keep your

coolants clean.

And with Alfa Laval’s centrifugal separators, it’s not much of

an effort to begin with.

Clean coolants save more than you think

Alfie 500 – worth evaluatingAlfie 500 is specifically designed toremove contaminants from coolants insmaller systems, using the time-testedtechnique of high-speed centrifugalseparation. With its compact design,Alfie 500 is easy to move across aworkshop floor. And you can use it toservice several tanks, or just one, forvolumes of up to 15 m3 (7,500 gallons).The equipment is easy to operatethanks to a PLC-based control panel.And just about anyone can quickly learn how to operate and service it.

Since the separator is installed in abypass flow, Alfie 500 can treat the

coolant during a production run or atstandstill. Alfie 500 separates tramp oilas well as metal fines and solid particlesdown to 1 µm from the coolant.

Recycling means major savings Install Alfie 500 and your fluids will lastmuch longer. Continuous cleaningextends the life of your coolants and,with top-ups, it can last as long as10 years!

Imagine the savings on fluid disposaland replacement. No filters to replaceor dispose of. Clean coolant is returnedto your tanks, “pure” free oil or tramp oilis collected in a tank and a compact

dry cake of particles collects on theinside of the separator bowl.

Precise tools – better end qualityIn light of today’s zero-defect produc-tion philosophy, Alfie 500 is a clearasset in any metalworking plant.

Clean coolant minimises tool wearcaused by contaminants, giving moreprecise machining and fewer rejects.

Keep your tools runningThe Alfie 500 will raise your produc-tivity. Clean coolants mean longer toollifetime and longer production runswithout tool changes. It also meansfewer breakdowns due to solid particlesclogging pumps and other equipment.Fewer stops for tank cleaning is yetanother benefit.

We see a potential to cut cost and boost productivity

• Low fluid replacement/disposal costs

• Longer tool lifetime

• Cleaner components, improved end-product quality

• Less downtime for service since theseparator is installed in bypass flow

• Fewer man-hours required for maintenance of service fluids

• Healthier work environment

• Reduced impact on the environment

Every machining stage in your plant needs coolants.Always having clean coolants offer clear benefits.

The Alfie 500 – look how easy

Install in any systemInstall Alfie 500 in a bypassflow. No redesign is necessaryon your machine.

Extremely simple to operateThe Alfie 500 is ingenious, veryeffective, and very easy to workwith. All functions are controlled by a PLC-based control system.And with a well thought-out design.

The Alfie 500 is the perfectsolution for cleaning coolants in metalworking operations.

Plug-and-play operationHook up Alfie 500 and start it up. The system works auto-matically and requires nosupervision. Your coolants willlast longer than ever before.

Support worldwide and around the cornerAlfa Laval’s global resourcesinclude 50 sales companies andan extensive Parts & Servicenetwork, supporting customers in more than 100 countries. A network of local distributorsand service providers can alsoprovide support.

� When the tramp oil hasreached a certain level in thecollecting tank, a microswitchis activated, stopping thecleaning process and turningon an indicator light.

� Mobile and compact. Largewheels make it easy to movethe Alfie 500 even when thefloor is not entirely smooth.

� The surface of the rotatingbowl is coated with a materialthat is 12 times harder thansteel.
