4.2 Cu. Ft. Vaccine Built-In Undercounter Freezer Certified to NSF/ANSI 456

The temperature setpoint range is -15°C to -28°C. Per the Temp Controller tab, controller settings must remain unaltered to ensure thermal performance compliant with NSF/ANSI 456 requirements.

The unit requires 110-120V AC with 15 A minimum. It ships with a NEMA 5-15 plug and a power cord typically 8 to 10 ft long, conforming to UL471 requirements and including a vaccine storage power cord warning label.

The freezer includes two shelves, and they are fixed.

The controller provides high and low temperature alarms compliant with the alarm requirements defined in the NSF/ANSI 456 standard for vaccine storage. State switching remote alarm contacts are also provided for an external alarm connection.

After a 60-second door opening, all probes recover to under -15°C within 8.2 min. During 5-second door openings, temperature did not exceed -17.5°C at any probe for all required NSF/ANSI 456 testing protocols.

The unit carries a two (2) year parts and labor warranty, excluding display probe calibration, plus a five (5) year compressor warranty.

NSF/ANSI 456 is the vaccine storage standard from NSF International, which sets performance and construction requirements for vaccine refrigerators and freezers. A certified unit like this one is tested by an independent third-party lab under protocols that go far beyond those for a standard pharmacy refrigerator: vaccine simulation devices are placed at worst-case positions inside the unit and temperatures are recorded 30 to 90 times faster than a typical data logger. It holds temperature within ±0.5°C, with forced-air circulation and dual temperature monitoring with audible and visual alarms. It is for anyone who stores vaccines or other temperature-sensitive pharmaceuticals and needs certified protection through heavy use and frequent door openings: pharmacies, clinics, physician offices, hospitals and immunization programs.
