Preventative maintenance (PM)

There are many aspects to look into when maintaining an Irradiator. Not only does it have to be radiologically safe and secure, but it also must function properly both mechanically and electronically as well to ensure safe use. Gamma Irradiator Service, LLC takes pride in the workmanship we perform, therefore offering a free 90-day workmanship warranty for all of our PMs. We will go over a lengthy checklist of the items that must be maintained on a routine basis to ensure the irradiator will keep performing at a high level without any interruption. A few of the items that we check during our preventative maintenance include, but are not limited to:

  • Microswitches
  • Batteries
  • Relays
  • Solenoids
  • Pneumatic Systems
  • Hinges
  • Bearings
  • Turntables

Not all irradiators are the same, but we provide preventative maintenance to a large variety, so make sure to give us a call or send us an email if you have an irradiator that is not functioning correctly or would like to have us look it over to make sure everything is working in a proper fashion. *Note: The FDA requires an annual dose validation and preventative maintenance on all irradiators that are used to irradiate human blood products.
