IF THE PRICE IS RIGHT, USED COOLANT FILTERS CAN BE AN ECONOMICAL CHOICE EVEN IF THEY ARE BIGGER THAN WHAT YOU NEED

If you need a filter quickly and your budget prevents the purchase of a new filter you can go shopping for a used coolant filter. The chances of getting a used coolant filter at the proper size are remote. So consideration must be given to filters either smaller or larger than what the system would normally use. Over sized used coolant filters can be a good buy for many reasons, the first two of which are if the price is right and if delivery meets the needed target.

The other reasons are related to the filters’ performance. Filters are selected on the basis of flow per square foot of filter area which is established for each different application. The flow rate is based on field experience of the application which balances the filter ability to achieve the desired clarity with an acceptable media usage rate. A larger filter does not have its designated flow sent through it. If the system uses a lower flow than the designed flow rate of the filter and the filter only handles the needed flow, the used coolant filter will achieve better coolant clarity with less media consumption.

The media reduction is significant. For example, field data shows that if a filter operates at a flow rate at 25 percent less than the design rate and nothing else changes, media consumption drops almost in half. If the filter operates at 50 percent the media consumption drops almost 70 percent. Also, since the media is staying in the bed longer it has an opportunity to generate a tighter film or cake from the intercepted contaminants. The tighter cake is a better media and the fluid reaches a higher clarity level.

Harrigan Solutions understands this phenomenon and can offer advice on how to incorporate a used coolant filter into your system. We offer engineering help on how to select, install and control the flow to the used coolant filter. We sell or rent new and used coolant filters depending upon the customers economical goals. Harrigan Solutions offers service programs where technicians can monitor the operation, perform routine maintenance, and train personnel for customers who do not have the staff to cover this area.
