General observations: Clean and in good overall cosmetic condition. This unit was removed from a premier state facility with a history of consistent maintenance and was released following standard state-regulated decontamination procedures. It has been cleaned, serviced, and is a solid performer overall. One notable dent is present on the lower left side panel. This is cosmetic only and does not affect performance or usability.
Facility Testing: This freezer was fully tested and successfully completed an extended 48-hour test run at -80°C. During our observations, the unit cooled quickly, maintaining a stable low between 79-81°C for the duration of the testing. Controls operated as designed. Door and battery alarm notifications were reliable. Current battery indicates low voltage. While it maintained disaplay and sensor readings after the unit was unplugged, we did not believe this was sufficient for clinical us. A new replacement battery has already been ordered and will be installed prior to shipping.
Additional notes: This system was serviced onsite. Filters and heat exchangers were thoroughly cleaned and the system should be ready for demanding facility use. Unit does show signs typical to clinical use but remains a strong performer. Please review all photos carefully for cosmetic details, overall configuration, and included components.
Included in listing: Comes exactly as shown in photos, with 2 removable styrofoam caps and power cord. A new replacement alarm battery will be installed prior to shipment.
