Preventative Maintenance Schedule

Category: Care & Maintenance
Topic: Preventative Maintenance

Most facilities have a pre-determined schedule of maintenance for the different categories of equipment. Hettich recommends cleanings and inspections of all Hettich equipment be conducted at regular intervals. For optimal results, Hettich suggest following the attached Preventative Maintenance Schedule.

Clean, Inspect & Lubricate

Category: Care & Maintenance
Topic: Preventative Maintenance

It is important to regularly clean, inspect and lubricate the rotor and accessories in all Hettich centrifuges. General maintenance procedures will ensure proper operations, provide optimal and consistent results plus extend the life span of all components. Regular inspection and lubrication can reduce the operational noise, decrease potential vibrations and prevent imbalance errors from occurring.

Installing and Removing a Rotor

Category: Care & Maintenance
Topic: Preventative Maintenance

Centrifuge rotors are designed to sit evenly and to fit tightly onto the motor shaft. When installing a rotor, be sure that particles of dirt do not adhere to the motor shaft and cause an uneven seating of the rotor. Be sure to grease the motor shaft on a regular basis to allow for easier removal in the future and to prevent the metal of the shaft from binding with the metal of the rotor.

Life Cycle Counts

Predictive Maintenance: Life Cycle Counts/Maximum Cycles

Like most mechanical devices, such as a car or truck, centrifuges follow a maintenace program and part replacement schedule base on maximum cycle counts. Although this can take many years, eventually the materials used in your rotor, buckets, and centrifuges will reach the end of their useful life. By performing mechanical stress tests, we have determined the maximum amount of cycles our products should undergo before being retired.

Lubrication of Rotor trunnions

Category: Care & Maintenance
Topic: Preventative Maintenance

The rotor trunnions are small steel knobs located at the edge of a swing-out rotor and support the centrifuge buckets. During centrifugation, the buckets will swing on the trunnions causing friction. For best results, general maintenance and greasing of the trunnions will decrease the friction and allow for an even swing of the buckets.

Proper maintenance will ensure your Hettich centrifuge performs for several years, even with continuous use. With safety always in mind, be sure to unplug the centrifuge before cleaning.

Surface Cleaning and Care

Category: Care & Maintenance
Topic: Preventative Maintenance

The outer surfaces of Hettich centrifuges are constructed of various painted metal surfaces and molded plastics. These surfaces stand up to most regular cleaning products such as "409", "Fantastic", "Simple Green", "Windex", etc.

Hettich suggests to avoid cleaners with ammonia as they may interact with LCD screens.
