Accucold's general purpose storage line includes upright manual defrost freezers designed for the storage of certain enzymes, reagents, samples, and other materials used in laboratory and clinical settings that require -20ºC temperatures with more stability than traditional no-frost equipment.

Model UFM19W is a front-opening freezer with an 18.3 cu.ft. interior storage capacity. Manual defrost operation ensures a more stable interior with none of the warming cycles that can compromise temperature in traditional frost-free cooling systems. The dial thermostat is located inside to prevent accidental temperature adjustments, with a thermometer/alarm mounted externally to ensure a readout of the current and high/low interior temperature is visible without opening the door. The temperature probe is encased in glass beads and positioned in a fixed shelf in the center of the unit to best simulate the temperature of stored items. We include an additional probe hole to accommodate additional monitoring equipment. Cantilevered shelving provides more flexibility in storage, with tight spacing between the pilasters so you can adjust as needed. This unit has a flat door liner to accommodate deeper trays. An automatic LED light makes it easy to see the full interior.

This freezer comes in a white exterior finish with a blue accent on the front. The keyed lock is conveniently located towards the top of the unit for easier user access. The reversible door includes an easy-grip handle in a brushed aluminum finish. This unit includes a 9'5" long power cord with a hospital grade 'green dot' plug for a more secure connection, ideal for high traffic environments. The cooling system utilizes hydrocarbon refrigerant for a greener footprint. For advanced insulation, the door features a vacuum seal that keeps all cold air inside. 

The UFM19W meets NSF-7 commercial standards and is ETL listed for the U.S. and Canada. It matches refrigerator model URM19W. It can be customized with additional features to best meet your storage needs, including digital data loggers (DDLs). For more information, contact our product specialists at 718-893-3900.
