    The Centrisys/CNP team understands that not all centrifuge repair and service is the same. We understand that any shut down due to a centrifuge malfunction or inaccessible spare part may result in an emergency situation. Given the multiple shifts most customers run each day, decanter centrifuges must run at peak efficiency during all operational hours.

    We’ve put together a helpful checklist below with 11 considerations for selecting the best decanter centrifuge repair facility so that you can be prepared next time you need to select the best service support. Let’s dive in...

    1. Ample Facility Space

    Ample Decanter Centrifuge Facility Space

    Does the repair facility have sufficient space to repair correctly and safely? Floor and overhead space should be part of this consideration. Is there enough space to thoroughly inspect, clean, and measure the decanter centrifuge and its parts? There must be ample room in the facility to view and analyze the reasons for equipment failure.

    A key measure of enough space in a decanter centrifuge repair facility is if a centrifuge skid system or a full centrifuge trailer system can be opened and repaired safely in the shop.

    Repair facility square footage(and aerial square footage for the use of cranes) is a key enabler in providing ample room to inspect, measure, and clean every piece of equipment to either determine the reason for failure or properly repair equipment.

    2. Current ISO Certification

    Current ISO Certification

    Does the decanter centrifuge repair facility maintain an up-to-date International Organization for Standardization (ISO) certification? You might ask, “why is this important?” ISO certification certifies that the processes and documentation have met all of the standardization and quality assurance requirements. ISO is an independent, non-governmental organization that develops standards to ensure the quality, safety, and efficiency of products, services, and systems.

    Centrisys/CNP is ISO 9001:2015 certified, which specifies requirements for a quality management system to demonstrate an ability to consistently provide products and services that meet customer and regulatory requirements, and enhance customer satisfaction through the practical application of systems and processes.

    Essentially, ISO standards are in place to ensure consistency, and decanter centrifuge repair facilities with current ISO certification and annual inspection have taken the time and made an investment to ensure they provide the highest level of quality and service.

    3. Holds Liability Insurance

    bonding-and-liability-insurance

    Does the decanter centrifuge repair facility have bonding and liability insurance? Liability insurance protects all parties’ interests in the event of a mistake, accident, or work stoppage issue that may occur during the course of operations. In short, liability insurance covers damage, injuries, and other problems that could happen during the repair.

    Surety bonds are also widely used in the construction industry and ensure that a project will be finished. They are designed to certify that a business acts in accordance with certain laws, and if the terms are broken, the harmed obligee can make a claim on the surety bond to recover losses incurred.

    4. Dedicated Quality Control

    quality-control-2

    In the same line as ISO certification and liability insurance, it is important to know if a decanter centrifuge repair facility has a dedicated quality control department?

    Quality assurance is achieved by establishing steps and procedures that require team members to implement a number of checks and balances before the completion of a project is approved.

    Quality-control processes ensure consistency and safety, potentially eliminating unnecessary costs and reducing the likelihood of liability claims and lawsuits. It is a vital element to providing high-quality products and services that exceed customer expectations. Specifically, Centrisys/CNP’s quality control processes, which include the tracking of incoming components and outgoing equipment.

    5. Access to High-Speed Balancer and Centrifuge Balancing Equipment

    High Speed Balancer

    Below is a list of a few questions you should ask related to balancing equipment:

    1. Does the decanter centrifuge repair shop you are considering have a high-speed balancer and balancing equipment?
    2. Does the balancing equipment run at full or over speed?
    3. Does the balancing machine balance above the first critical speed to account for flexible rotors?
    4. Is the balancing machine capable of three plane balancing?

    Balancing equipment at high speeds, as you can imagine, is not advised without proper protection and protocols. This is why at Centrisys, we’ve created an innovative approach with our state-of-the-art balancing bunker.

    Centrifuges sent to Centrisys for repair or rebuild and then require balancing are done in our Centrifuge Balancing Bunker. This dedicated shop space provides the necessary safety and protection of employees and customers who come to witness the operation. It not only provides for noise reduction during high-speed balancing, but it affords a much-needed measure of safety for our operators and service technicians.

    6. Utilizes Overhead Cranes

    Below is a list of a few questions you should ask related to the use of overhead cranes:

    1. Does the decanter centrifuge service center have overhead cranes to load and unload equipment in a safe manner? (Cranes are also used in the assembly/disassembly of equipment)
    2. How many are in the shop and what kind?
    3. Is the crane load weight sufficient for your needs?

    There are many options to lift and move heavy equipment around a repair shop, but the most efficient and safe way is by using cranes. Overhead cranes have higher loading and unloading capabilities and can lift a wider variety of equipment. They are essential when it comes to the assembly and disassembly of the centrifuge during a repair. If a repair shop has invested in overhead cranes, they have invested in both the most efficient process of centrifuge service and repair, as well as the safety of their employees. Centrisys/CNP currently has over 25 cranes in all of its service shops ranging from 15-ton to half-ton jib cranes. All of the company’s cranes are certified and inspected annually by a third-party crane manufacturer. A third party safety trainer performs regular employee crane training.

    7. Covers Centrifuge Repair and Parts Under Standard Warranty
