Accucold's Nutrition Center Series features commercially approved refrigerators and freezers specifically designed for the storage of sealed food and beverages in a variety of facilities, including break rooms, waiting areas, nurses' stations, and more. The FF31L7NZ is a compact all-refrigerator for countertop use. It is ETL-S listed to NSF-7 standards, with a temperature range of 35 to 39 F ideal for sealed food and beverage storage. The top includes a continuous external display of the current and minimum/maximum temperature to the nearest tenth of a degree, making it easier for staff to monitor and record the temperature as needed. This device includes a built-in audible alarm that will sound if the unit rises or falls out of the set temperature range. The temperature probe is encased in a glycol-filled bottle to best simulate the temperature of stored contents. All temperature display devices are calibrated to NIST standards in our ISO/IEC 17025:2017 laboratory and include a certificate of calibration. Inside, the FF31L7NZ utilizes low maintenance automatic defrost operation. Four adjustable chrome shelves allow users to reconfigure the interior to accommodate a variety of sizes, with a flat door liner to allow easier storage of deeper items. The flat door liner helps to maximize the interior depth. The digital thermostat is located inside and can be managed in Celsius or Fahrenheit. Interior LED lighting offers an attractive, energy efficient view of the interior in a soft blue hue. The FF31L7NZ comes in a white exterior finish. The user-reversible door includes a front lock for keyed security. The rear features a sealed metal cover for easier cleanup, ensuring dust and other particles won't affect the cleanabililty of the exterior. Designed specifically for institutional food and beverage storage, all Accucold's Nutrition Centers are commercially approved to NSF standards and comply with most JCAHO recommendations for safe storage. Additional sizes and variations are available.
