BENEFITS OF S·O·S FLUID ANALYSIS

S·O·S Fluid Analysis helps identify minor issues before they evolve into expensive ones. This process allows you to stay on top of your machine’s condition to protect its integrity, optimize its performance and maximize its productivity — all of which will help you lower costs and boost resale values. Routinely testing the fluids in your equipment from offers extreme benefits including:

 

  • Early detection of problems, so they can be repaired before becoming major failures
  • Performance monitoring – positive and negative – so that you won’t pay for component repair prematurely
  • Maintenance monitoring that enables you to verify routine services have been performed
  • Budget and timeline management for projects and planned repairs, downtime and overall equipment life management
  • Service history tracking for each machine, providing valuable insights for evaluating performance, planning replacement purchases and commanding higher prices at trade-in or sale

Sophisticated Analytical Technology Is The Key

Maximize your equipment’s life span with S·O·S Fluid Analysis services from Warren CAT. Our experienced technicians leverage state-of-the-art, highly sophisticated analytical technology to regularly inspect oil, coolant and fuel samples. They’ll perform four kinds of tests on your machine’s drive train, hydraulic and engine fluids, looking at factors such as:

 

  • Component wear rate
  • Oil contamination
  • Oil identification
  • Oil condition

 

Our Cat-certified interpreters will look at the results and generate a detailed report alerting your crew to potential issues and offering insight into practical maintenance practices that will improve your equipment’s productivity on the job.

Fluid Sampling Kits

While your equipment may look great outside, internal equipment issues could put your operations at risk. At Warren CAT, we strive to give you a transparent picture of your machine’s end-to-end condition by offering the following sampling kits to test your equipment on your own.

Diesel Exhaust Fluid (DEF)

  • DEF Testing takes an oil sample to confirm urea content and uncover any contamination.
    Kit: Diesel Exhaust Fluid / Part #OILSMPL1

Oil Sampling

  • Oil Testing, with elemental analysis, oil condition check, viscosity check, particle count for cleanliness, physical testing to identify water and analytical testing to quantify fuel and coolant contamination.
    Kit: Oil Sample / Part #: OILSMPL1

Coolant Sampling

  • Level 1 Testing, for frequent monitoring, provides information regarding crucial characteristics such as pH, glycol percentage, boiling and freezing points, total hardness and conductivity and includes a visual inspection for oil, odor, foam and solids.
    Kit: Coolant Level 1 / Part #: COOL1
  • Level 2 Testing, for advanced testing including all the Level 1 tests plus chemical composition analysis to provide an in-depth view of coolant condition.
    Kit: Coolant Level 2 / Part #: COOL2

Fuel Sampling

  • Fuel 1: Basic Fuel Testing provides biodiesel content, elemental analysis, Karl Fischer water, microbial growth, particle count, sulfur content and visual inspection.
    Kit: Basic Fuel / Part #: FS1
  • Fuel 2: Fuel Monitoring can help identify diesel contamination such as gasoline with color, density, distillation curve, cetane index and viscosity while still providing all the tests of Basic Fuel (Fuel 1).
    Kit: Fuel Monitoring / Part #: FS56
  • Fuel 3: Fuel Storage provides long-term storage parameters such as clear and bright, flash point and oxidation stability, as well as biodiesel content, elemental analysis, Karl Fischer water, microbial growth, particle count, sulfur content, visual inspection, cetane index, color, density, distillation curve, viscosity.
    Kit: Fuel Storage / Part #: FS57
  • Cold Test, an additional test used within colder temperatures to identify various factors, includes cloud and pour point and the fuel’s cold filter plugging point.
    Kit: Cold Test* / Part #: COLDTEST (*Cannot be purchased without a fuel kit)
