USED COOLANT FILTERS CAN BE ECONOMICALY JUSTIFIED

If used coolant filters have had proper maintenance in their previous lives or have been reconditioned, their selection for an application carries little risk when considering the cost to obtain it. The pricing is often the main reason for the project to get management approval. The economic justification is hard to pass up.

Probably the flat bed pressure filter has the best potential to offer good longevity as a used unit since it has few moving parts exposed to the dirty liquid and it uses a pump-fed, closed pressure chamber to force the contaminated fluid through the media.

Harrigan Solutions engineers know the parameters of the various filters and they are careful of how the filter is to be installed. They have an inventory of used coolant filters and they can assist in selecting the best approach for the application. Harrigan Solutions' marketing concept offers their customers the options of buying the filter outright, renting, or leasing on a monthly basis. The customer can also enter a service agreement where Harrigan Solutions' field engineers can maintain the equipment either on a routine schedule or as needed. this work is accomplished by working with the plants existing maintenance department.

USED COOLANT CENTRIFUGES CAN BE WELL JUSTIFIED FOR TRAMP OIL REMOVAL

Since centrifuges are often sought after for tramp oil removal, used coolant centrifuges can be sized and priced to make an installation economically feasible. Centrifuges are so efficient as a tramp oil separator, a low flow unit can keep the tramp oil level of a large reservoir from growing more than 2 percent concentration.

Harrigan Solutions' engineers have the experience to analyze a facility with a high tramp oil level and determine the best approach to solve the problem. In many cases they go beyond just applying a centrifuge. There may be other steps that could be taken to minimize the leakage which could significantly alter the strategy for sizing a centrifuge. They look at everything that impacts the occurrence of tramp oil. The study even includes the type of lube and hydraulic oils used by the plant since they may be contributing to the dissolved tramp oil problem.

When a centrifuge is selected, Harrigan Solutions will offer the options of purchasing outright, renting or leasing. We also offer service agreements to cover a range wide of possibilities including operating the units for the customer, or maintaining them as an extension of the customer's maintenance department.

USED CENTRIFUGE PRICES COULD MAKE A DIFFERENCE IN THE INSTALLATION'S JUSTIFICATION

Used centrifuges are now more readily available and the lower cost of a good reconditioned unit could make a difference in the economic feasibility of an installation. Well built units which have been maintained during their initial installation or successfully reconditioned still have a significant economic life where centrifugation is needed for liquid/liquid or liquid/solid separation.

Harrigan Solutions carries an inventory of used centrifuges and they can assist in selecting the proper used centrifuge for the application. They can participate even further by offering proposals to install and/or operate the units. They also lease the equipment for installations where the customer needs the cash flow advantage. Harrigan Solutions has developed a series of service agreements where they can perform routine scheduled maintenance or repairs as required.

PRESSURE FILTERS REMOVE SOLIDS FROM LIQUIDS BUT ALSO HELP REMOVE SOLIDS FROM THE PLANT

Flat bed pressure filters actually perform two tasks while they are filtering metalworking fluids.

The pressure filter takes the solids out of the liquid and also takes the liquid out of the solids:

• First, they remove the contaminants from the fluid so the "cleaned" coolant can continuously serve the operations without the need for frequent dumping. This is the typical filtering function.
• Second, the pressure filter extracts the free fluid from the accumulated solids so the "drier" solids are easier to discard. This is accomplished when the pressure filter is ready to remove the accumulation of contaminants, it pressurizes the chamber so air will perk through the cake and extract free liquid.

Harrigan Solutions engineers understand the value of the ability to remove solids from a plant without the concern of a sloppy mess. Also, the dewatered material could have a higher salvage value because it does not need the heat energy to evaporate the free fluid.

We provide the engineering and knowhow to select and install pressure filters. We sell or lease new and used equipment for our customers to stay within their budget limits. In addition we offer service agreements to operate and/or maintain systems.

METALWORKING FLUIDS ARE IN FOUR BASIC CATEGORIES

Metalworking Fluids are found in four basic categories for the general metalworking operations:

• Straight oils.
• Waterbase emulsions where a mineral or animal oils is emulsified into water.
• Semi synthetic solutions which blend man ingredients with natural oils and water.
• Synthetic solutions which are entirely man-made products.

Each has its place in the metalworking field and has exhibited its suitability for various applications. As the technology progresses, the supplier is able to incorporate certain additives so the blended fluid came perform better and cope with the challenges found in today's metalworking operations.

One of two key factors which is considered when developing metalworking fluids is the fluids' filterability. The fluid must be able to be cleaned with known practical methods without destroying its integrity or requiring an unrealistic cost to accomplish the cleaning function.

The second factor is the ease of safely disposing the metalworking fluids once they are rendered no longer useful. The process for disposal must be safe and economical without creating other hazards to equipment, personnel and environment.

Harrigan Solutions understand these needs and has the experience to aid in selecting a fluid as well as providing techniques to clean or dispose of them. They offer engineering and equipment for most cleaning functions including filters, separators, and centrifuges. They recognize the need for effective economic justification so they sell new or used equipment to aid in meeting the plants' budgets. Rental or lease programs are also available. Plus, service agreements for operating and/or maintaining the system will help a plant either train their personnel or ease the burden of the existing maintenance staff.

INDUSTRIAL LUBRICANTS SHOULD BE MONITORED FOR USEAGE RATE

When using industrial lubricants on metalworking machines using coolants "more" is not better.
The problem is not with the lubricating function but with the fact that the excess industrial lubricants enter the metalworking coolant to become a tramp oil. The excess lubricant carries two costs; initial cost to supply and the removal costs to separate the tramp oils from the waterbase fluids. Therefore it is an important cost reduction strategy to train operators on using the proper amount and teach them about the importance of monitoring automatic dispensing. Obviously there will not be total control and oils will enter the coolant routinely. The key is to keep it at a minimum and install effective equipment to keep the tramp oil levels below dangers levels.

Harrigan Solutions understand the nuances of industrial lubricants selection and control. We design tramp oil removal systems and provide the equipment to perform the liquid/liquid separating function. The equipment can range from settling, coalescing, decantation, skimming to centrifugation.

We sell new and used centrifuges which are one of the most popular devices for removing tramp oils from coolants. We also have service contacts at various levels of involvement for operating and/or servicing the cleaning systems.

CUTTING FLUIDS DO MORE THAN JUST REMOVE HEAT

Heat removal is the main function of cutting fluids, but that is not all they do. There are many more important roles cutting fluids play in the metalworking operations:

1. Remove the chips, swarf and debris which accumulate around the workpiece.
2. Flush the unwanted material away from the machine's critical wear surfaces.
3. Send the contaminants either to a sump or through a dirty fluid coolant return network
4. Coat the freshly cut surfaces of the workpiece with a film as a antiwelding barrier so the freshly cut chips do not reweld back onto the workpiece.
5. Provide a coating to protect the workpiece and machines surfaces from corrosion.
6. Lubricate the friction surfaces of the machine.
7. Keep fixtures and nests clean for proper positioning of the workpiece
8. Keep automatic gauges and part handlers free of debris

Obviously in order to accomplish these tasks the cutting fluids should be maintained at an acceptable clarity level. Harrigan Solutions has a staff who understands the functions and expectations of good clean cutting oils. They can help select the fluids and show what is needed to maintain them. Harrigan Solutions is a company which is proactive to solve problems wherever they may be. They design systems, sell equipment, and provide follow up action where needed. They:

• Sell new or used equipment to meet limits in budget.
• Lease equipment to meet limits in cash flow.
• Offer service agreements for operating and/or maintaining equipment to meet the limits of available staff.

COOLANT RECOVERY HAS MORE THAN ONE MEANING

Coolant recovery is one of the industry's terms which can depict different images with different people.

• The most common use of the term "coolant recovery" is when a coolant is taken off-line when it reaches a level of contamination where it can no longer function properly. The dirty coolant is sent to an off-line cleaning module where it is cleaned, dosed with needed additives and sent back to the line for continual use.
• The second use of the term is where the removed coolant is considered spent and a remote process is used to clean, separate and treat the fluid so it can be recycled for another function.
• The third use of the term coolant recovery is probably the most popular process but the term is least used to describe the process. The coolant is continuously cleaned on line so its life is extended to where it should not have to be discarded due to suspended contamination. The reason why the term coolant recovery is not used often is because the coolant is not really lost so it does not have to be recovered.

We at Harrigan Solutions understand the meanings and the various needs where each would be applied. We sell new and used filtration equipment. Also, leasing arrangements are common. Service agreements can be arranged to operate and/or maintain equipment; either on a as needed basis or a routinely schedule program.

COOLANT FILTRATION IS HANDLED IN MANY DIFFERENT CONCEPTS

Coolant filtration can be arranged in many different concepts which offer flexibility for designing a system to meet the varying needs of metalworking installations.

1. Full Flow is where a system sends all the liquid through a cleaning device before the fluid is sent back to the process. This is the primary targeted design when planning a system since it is the most fool proof. The flow to the filter is slightly greater than the flow to the process.
2. Side Arm Flow is where a cleaning device pulls a given amount of liquid from a reservoir , cleans it, and sends the coolant back to the same reservoir. The amount of flow is adjustable depending upon the size of the tanks, the application and the basic needs of the fluid.
3. Batch Flow is the technique of removing a given volume from the system and sending it to a remote off-line cleaning module. The module will hold enough clean liquid to replace the volume of dirty liquid just removed from the line. The size and flow rate are selected with the consideration for turnover rates, clarity needed, labor involved and physical layout of the facility.

The engineers at Harrigan Solutions understand the three concepts and have the know how to apply them for specific applications. They sell new and used filters and can arrange leasing as well as service agreements. The roster of devices can include all types of filters, centrifuges and other cleaning techniques.

COOLANT FILTERS WHICH USE ROLL MEDIA OFFER FIELD FLEXIBILITY TO COPE WITH VARIABLES

Coolant Filters are built with a number of designs and styles. Those which use roll media or reusable belts and are automatically self cleaning offer the most flexibility to cope with the variables a metalworking system may encounter. This class of filters are often referred to as flat beds, although some designs use a circular bed or rotating drum. The driving force is gravity, pressure or vacuum. Since they have the ability to sense the loading of the media and automatically replace it, they adjust the media usage rate as the contaminant load varies. Therefore, applications which generate contaminants as a direct result of the operation usually have a high probability that a self cleaning with automatic indexing filter will satisfy the need. These include (but not limited to) all metal cutting, forming,surface preparation and heat treating operations.

Of course the selection depends upon the size of the system, type of application and the characteristics of the contaminants. Harrigan Solutions has the experience to help select, improve or upgrade coolant filters for the full range of metalworking applications. We offer:

• New and used filters
• Filters for rent or lease
• Service agreements for operating and/or maintaining filters

ALFA LAVAL CENTRIFUGES REDUCE OPERATING COSTS

Alfa Laval Centrifuges may have the image of a high cost item but they do reduce operating costs and can show economic justification for many applications. Properly positioned in a coolant system Alfa Laval Centrifuges will remove fines and tramp oils which may migrate throughout the system regardless of the type of main filter already on the system. Alfa Laval Centrifuges can also be portable units which can be moved among a number of machines to clean the dirty fluid in their sumps. The cleaning function:

• Extends coolant life
• Lowers the amount of fluid dumps
• Increases tool wear
• Reduces scrap
• Eases the machine tool maintenance
• Produces consistent workpiece quality

Harrigan Solutions has the experience to assist in evaluating the potential return on investing in a centrifuge. They sell and also rent or lease centrifuges. They have an inventory of reconditioned centrifuges as well. Also, to make the project more feasible Harrigan Solutions offers service agreements to operate and/or maintain Alfa Laval Centrifuges.

USED FILTRATION EQUIPMENT CAN BE THE ANSWER TO REVAMPING AN OLD SYSTEM

Used filtration equipment can be the economical answer to revamping an old outdated system which can not justify a totally new system. Old tanks and pumps can be kept in place while the old cleaning device is replaced with a reconditioned filter or centrifuge. For example an old style suction filter with its own conveyorized tank can be upgraded by removing the suction filter components and adapting the existing tank to receive a new or reconditioned flat bed pressure filter. Assuming the capacities are within the design and the tank and pumps are usable the system can be revamped at a minimum of cost and lost time.

We have the know how to review any industrial liquid system to determine the feasibility of modernizing it. We are a proactive organization where we:

1. Provide used equipment if it fits the need.
2. Oversee or actually install the upgrade.
3. Lease equipment
4. Offer service agreements to operate and/or maintain the system.
