Fluid Analysis

Analyzing system fluids provides a snapshot of internal conditions
• Identify minor problems to avoid major failures.
• Extend equipment life—Contaminant levels in fluids dictate when to replace filters.
• Increase oil drain intervals—The condition of your oil indicates when oil changes are actually necessary.
• Increase resale value—Systemgard records prove your equipment has been maintained.

What is Fluid Analysis?
In our fluid analysis program, fluids are taken from several areas in your equipment and are analyzed by qualified laboratories to determine levels of contaminants in the various fluids. The level of each contaminant is compared to normal wear rates, so that potential problems with components can be identified before failure. The trends for the contaminant levels in your equipment also provide valuable information on potential problems.
The laboratories are ISO 17025 A2LA accredited, which is the highest level of quality certification for testing laboratories by the American Association for Laboratory Accreditation. You can be confident that the results are accurate, repeatable and backed by stringent laboratory standards.
Hills Machinery monitors your fluid analyses. We will provide guidance on necessary repairs and filter and oil change intervals, based on the results for your equipment.

Sampling Intervals
Manufacturers recommend sampling intervals for each model. Also consider how critical each piece of equipment is to your production in determining sampling frequency. You may want to reduce the hours between sampling periods for equipment operating under more stressful conditions, such as those in a very hot, dirty environment, or machines used for short trips with heavy loads or those with excessive idle times.

General Guidelines for Sampling Intervals

Engines 250 hours or at manufacturer’s recommended change intervals
Transmissions250 hours or at manufacturer’s recommended change intervals
Hydraulics250 – 500 hours
Differentials750 hours
Gearboxes750 hours
