Success Story: Vacuum Dehydrators and Paper Mills

July 20, 2015

We received a call from a large paper mill customer who had a high percentage of water in their oil reservoir.   They were looking for an immediate solution to reduce their downtime and prevent equipment failures.  Before we could offer them a solution to their problem, we needed a little more information on the application.  We asked them a few basic questions:

  • What is your current ISO Code?
  • What is your target ISO Code?
  • What is your reservoir capacity?
  • What is the % of water ingression?
  • What is the target moisture content?

It turns out that their oil reservoir had a 500 gallon capacity and a high percentage of water ingression. After getting the answers we needed, we determined that we had the perfect size Vacuum Dehydrator in our Rental Fleet to meet their needs.  We also equipped the dehydrator with a 6 micron Beta 1000 rated particulate element to help hit their target ISO Code.

The customer placed the order and we were able to deliver and get the unit installed in less than 24-Hours.

Vac_Microglass_FilterAfter installing the Vacuum Dehydrator, the paper mill saw an immediate reduction in both their water ingression and ISO Code.  It worked so well, they have decided to continue to rent the dehydrator while they complete repairs to their cooler unit.

Oil Quality and Our Drum Top Filter System

July 16, 2015

Last week a large paper mill ordered a second Drum Top Filter (DTF) system and Recirculation Adapter Kit to help with their Oil quality Improvement Program.  They had so much success with the first Drum Top Filter System they ordered that you had to get another one.DTF Steel Filter Unit Back

Our customer liked the fact that we were able to customize the flow rate of the Drum Top Unit from the standard 1 GPM to 5 GPM.  The higher flow rate worked better for their application.  They also liked that the Drum Top Filter (DTF) Unit sits directly on top of a 55 gallon drum.  Not only does it take up less space, it makes recirculating the drum that much easier.  Especially when utilizing our Recirculating Adapter Kit.

Drum Top Recirculating Adaptor KitThe Recirculation Adapter Kit includes a desiccant breather with adapter and threaded insert with an oil suction wand and an oil return wand. The desiccant breather fits into the smaller drum opening. The threaded adapter with wands fits into the larger the drum opening. These components allows the user to create a sealed reservoir out of 55 gallon drums.

High Velocity Flush of Hydraulic Power Units

July 6, 2015

In the fall, PFPUSA had a customer call in to rent one of our Hydraulic Flushing Skids to flush a hydraulic system.  Their client had four old hydraulic power units (HPU)s that needed to rebuilt and flushed.

The hydraulic power units are a critical piece of equipment in the production process. The units supply power to the friction welders, which build the drive shafts. Needless to say, the HPUs play an important role in the production process.

The problem was that the units were running extremely hot, causing the company to make repairs frequently, sometimes daily. This lead to costly downtime and required the HPUs to be repaired immediately.

With a quick turnaround required, PFP shipped a 75 GPM Flushing Skid to flush the hydraulic lines and steel pipe fittings. By incorporating our Absolute Rated Microglass Filter Cartridges, the customer was able to achieve their target ISO code in a timely manner.

PODS In addition to the flushing skid, we provided our Portable Online Diagnostic System (PODs) in order to verify that the target ISO Code was achieved. Utilizing the PODs unit allowed our customer to determine when they achieved their target ISO Code on-site. No need to send an oil sample out to be tested.

The end result was four completely rebuilt and flushed Hydraulic Power Units and ultimately a happy customer!

High Flow, Clay Treater, and Coalescer Separator for NGL Application

Particulate Filter, Clay Treater, and Coalescer/Separator for NGL Application

A customer of ours was commissioning a new NGL distribution line. After gaining an accurate understanding of the application and quality goals, I was able to specify and deliver the appropriate filter vessels and elements within a few days. The most difficult challenge for our customer was time, or a lack there of. The immediate demand to provide product required a solution…FAST!

An additional challenge was a higher than standard design pressure of 285 PSIG. Fortunately, PFP maintains a significant rental fleet ranging from portable hydraulic filter carts to high flow pipeline filter vessels.

To guarantee the delivery of high quality product, a three-stage system with specific filtration technology was required to protect from potential contaminants…

  1. High Flow, Clay Treater, and Coalescer Separator Installed at Customer Location

    Particulate Filter, Clay Treater, and Coalescer/Separator Installed at Customer Location

    Particulate Filter: Removal hard particulate contamination such as pipe scale and dirt

  2. Coalescer/Separator: Aids is the coalescing and removal of water droplets
  3. Clay Treater: Absorption of chemical contaminates such as drag reducers, color bodies and surfactants.

Currently the system is operating perfectly and will continue to achieve quality goals until we build and ship the brand new system!

Call us to discuss how we can help you achieve and maintain your high quality product goals!

Heavy Equipment Service Center – Oil Cleanliness

May 5, 2015

LSF Filter UnitsAchieving target oil cleanliness levels when maintaining and repairing heavy equipment is critical to maximizing component life.

Recently we developed a specific plan and provided the filtration components to allow a local company to achieve their oil quality goals throughout the entire facility.

LargHydraulic Cartridge Housingse cartridge filter housings were provided to not only filter inbound oil, but also to provide kidney-loop or “multi-pass” capabilities in each oil storage reservoir. We then provided point-of-use filter housings at each hose reel and dispensing point throughout the plant. This combination ensures that oil will be filtered ever time it is transferred.

Adequately sized filters constructed with high efficiency, “absolute rated” filter media will provide significant dirt holding capacity, as well as, target ISO Cleanliness Codes. In addition, differential pressure indicators and electrical connections were provided to ensure filters will be changed-out as efficiently as possible, providing an even greater cost savings.

Give us a call at 888.679.6645 to discuss how we can help you improve your oil quality and maximize your equipment life.

How to Determine Correct Media Size for Achieving Target ISO 4406

January 21, 2015

ISO 4406 Cleanliness ChartOur sales manager forwarded me an email the other day from a researcher at a university who was confused about how to select the proper size of filter media in order to achieve a certain level of cleanliness according to the ISO 4406 standard. I proceeded to explain the following to him.

Referencing the document in question, “Understanding ISO Codes” (PDF), on the second page, the column labelled “Media” describes the recommended pore size of the corresponding filter media necessary in order to achieve the ISO code listed in the column to the left of the media size.

Please note that the examples listed are for systems using petroleum-based fluids per ISO 4406:1999, and for the following particle sizes:

4μ[c] / 6μ[c] / 14μ[c] (where each size corresponds to an ISO code number)

For example, in the chart you can see that for a servo valve with fluid operating up to 3000 PSI, the recommended target ISO cleanliness code is 16/14/11 and, in order to achieve this ISO code, the corresponding recommended media pore size is 5 micron (using an older testing method with a “beta[c] ratio” of 1000) and 3 micron (using the new testing method with a “beta ratio” of 200).

The “beta ratio” is the ratio between the number of particles per unit volume above a specific size in the suspension upstream of the filter to the same parameter in the flow downstream of the filter. The beta ratio of any particular filter is determined in a special test rig that enables accurate particle counting in its upstream and downstream flow regions. This simple ratio can be described by the following formula:

βx = Nu / Nd

where: “x” is the beta ratio for particles larger than x μm, “Nu” is the number of particles per unit volume larger then x μm upstream, and “Nd” is the number of particles per unit volume larger then x μm downstream. The higher the value of the beta ratio, the more particles of the specified size (or greater) are retained in the filter.

One insight that should be noted is that the filter efficiency (in percentage) at any particle size can then be determined directly from the beta ratio by using the following formula:

Ex (%) = 100 (βx – 1)/βx

For example, as mentioned in “Understanding ISO Codes“, a beta ratio of 1000 equates to a filtration efficiency of 99.9%:

Ex = 100 (1000-1)/1000 = 99.9%

and a beta ratio of 200 equates to a filtration efficiency of 99.5% efficiency.

Does this help you to understand better how to select filter media to achieve oil cleanliness?
