The UCF-101A is the 90 L (3.2 cu.ft.) digital freezer in Yamato's UCF undercounter/countertop series — an adjustable -10°C to -25°C / 14°F to -13°F solid-door lab and pharmacy freezer that adds USB PDF data download, a back-up alarm battery, and mobility casters to the digital feature set. It is the right pick where a facility needs the larger 90 L volume plus a fully documented, alarm-protected cold chain in a rollable undercounter cabinet. Its sister UCF-101B shares this cabinet but reaches -40°C for deeper-cold storage.

Application Profile
The UCF-101A fits larger-volume, fully documented frozen storage at the undercounter footprint. Its USB PDF export supplies auditable temperature records for QC, GMP, or regulatory files, while the back-up battery keeps alarms live through a power interruption so excursions are still annunciated. The 90 L cabinet holds higher-capacity reagent and sample banks at an adjustable -10 to -25°C near the point of use, and the dry-contact alarm relay ties into facility monitoring. Two rear casters plus two front leveling legs let the cabinet roll and then lock into position for mobile or reconfigurable labs.
Where storage colder than -25°C is required, choose the sister UCF-101B (-40°C on R290).
Design Architecture
Refrigeration. A hermetic compressor with R600a hydrocarbon refrigerant provides direct cooling across the adjustable -10°C to -25°C range, drawing ~1.66A running. US EPA / SNAP-approved insulation stabilizes the larger 90 L cabinet. The unit is UL listed.
Control, monitoring, and documentation. A digital display manages the setpoint. Alarms cover high/low temperature, door ajar, power failure, low battery, sensor failure, and USB failure; min/max display and reset; data logging runs at adjustable intervals; and records download via USB in PDF format for audit trails. A back-up battery powers the alarm circuit only during outages, and a dry-contact relay enables external monitoring.
Cabinet and access. Painted-steel exterior, painted-aluminum interior, 2 adjustable shelves plus a base shelf, and a 1" access port for probe pass-through. The keyed lockable solid door secures contents; 2 front leveling legs and 2 rear casters provide roll-and-lock mobility. Defrost is manual.
Electrical. Standard 115V, 60 Hz, single-phase power on a 15 Amp dedicated line via NEMA 5-15 plug.
Frequently Asked Questions
What temperature range does the UCF-101A hold? An adjustable -10°C to -25°C (14°F to -13°F), managed from a digital display with high/low temperature alarms.
How large is the UCF-101A? 90 L / 3.2 cu.ft. internal, with external dimensions of 23.75" x 21.5" x 32" (W×D×H) and a weight of 165 lbs.
Can it produce auditable temperature records? Yes. Data logging runs at adjustable intervals and records download via USB in PDF format for QC, GMP, or regulatory files.
What happens to alarms during a power failure? A back-up battery powers the alarm circuit only, so power-failure, door-ajar, and temperature excursions are still annunciated during an outage.
How does the UCF-101A differ from the UCF-101B? Both share the 90 L cabinet. The UCF-101A reaches -25°C on R600a refrigerant; the sister UCF-101B reaches -40°C on R290.
