Preventive Maintenance

The ACS preventive maintenance program will help prevent equipment failure before it occurs!

ACS 's preventive maintenance can be simply described as maintenance of equipment or systems before failure occurs. It is divided into two subgroups:

  • Planned maintenance
  • Condition-based maintenance

The main difference between the subgroups is the determination of maintenance time, or to determine the moment when maintenance should be performed.

ACS knows that preventive maintenance is considered to be worthwhile: there are risks such as equipment failure or human error involved when performing maintenance, just as in any maintenance operation. Preventive maintenance as scheduled overhaul or scheduled replacement provides two of the three proactive failure management policies available to the maintenance engineer. Common methods of determining what preventive (or other) failure management policies should be applied are: OEM recommendations, requirements of codes and legislation within a jurisdiction, what an "expert" thinks ought to be done, maintenance already done to similar equipment, and most important measured values and performance indications.

We make it simple:

  • ACS's preventive maintenance is conducted to keep equipment operating and/or extend the life of the equipment.
  • ACS's corrective maintenance, sometimes called "repair," is conducted to get equipment operating again.

The primary goal of maintenance is to avoid or mitigate the consequences of failure of the equipment. This may be done by preventing the failure before it actually occurs, which "Planned Maintenance and Condition Based Maintenance" will help to achieve. It is designed to preserve and restore equipment reliability by replacing worn components before they actually fail. ACS's preventive maintenance activities include partial or complete overhauls at specified periods, oil changes, lubrication and so on. In addition, service technicians can record equipment deterioration so they know to replace or repair worn parts before they cause system failure. Less downtime results in more production achieved.

Professional Calibration

Advanced Chambers Services understands the critical role that calibrations have in your regulated industry, which is why we use extremely precise calibration standards. The use of these standards will ensure that your instruments are calibrated to a standard (ISO 17025) which will meet or exceed manufacturer’s specifications. We can also offer programs that are tailored to fit your needs, such as single point or loop calibrations and verifications.


ACS's procedure provides you with your set points "as-found" calibration verification. The "as-found" readings are documented and verified to be within the manufacturer's tolerance, if found within the tolerances the device is then returned to service. If any instrument exceeds the tolerance, we will promptly notify you, so that we can take the necessary steps to adjust and document the event.

Additionally, if the "as-found" readings are not within the manufacturer's tolerance, the instrument is then calibrated using the manufacturer's calibration procedure. After completing the calibration, the instrument's "as-left" readings are documented using the same set points from the calibration verification to ensure the instrument is reading within the manufacturer's tolerance.

All personnel performing instrument calibrations will be trained on the most recent revision of company's System Calibration Procedures (S-1) and ISO 17025 compliant.
