Accucold manufactures purpose-built freezers designed to meet the rigorous standards of NSF 456 for the stable storage of vaccines and other pharmaceuticals. The VT65MLVAC456ADA is a 24" wide 32" high all-freezer with a front-breathing design and fully finished exterior to allow built-in installation under lower ADA compliant counters or freestanding use. The digital microprocessor temperature controls are pre-set and locked at -30 C to prevent accidental adjustments (if you need to adjust the temperature, contact our Technical Support team). As recommended by VFC programs and the CDC Vaccine Storage and Handling Toolkit, this unit includes a NIST calibrated thermometer that displays the current, minimum, and maximum temperatures to the nearest tenth of a degree with an external readout viewable in Celsius or Fahrenheit. A two-year certificate of calibration is included for your facility's records. The thermometer features an audible alarm to warn users if the interior has gone out of the programmed temperature range. The buffered temperature probe is encased in a glycol-filled bottle to best simulate the temperature of other stored contents, resulting in the utmost accuracy for temperature reporting. We include a pre-installed 3/8" probe hole for users who wish to install additional monitoring equipment. This freezer's temperature is pre-set and locked at -30 C to prevent accidental temperature adjustments (if you need to change the temperature, contact our Technical Support team for assistance). The extra thick insulation and static manual defrost cooling system offer reliable temperature stability. The overall capacity is 3.2 cu.ft., with a 1.85 cu.ft. of usable space for vaccine storage. Three slide-out drawers on fixed shelves allow you to store contents easily. The drawers are made from clear plastic, allowing you to view contents while protecting them from warmer air when the door is opened. As required by the NSF/ANSI 456 standards, the interior includes a defrost indicator to alert users when it is necessary to defrost. The VT65MLVAC456ADA features a factory-installed lock located towards the top of the door for convenient access, with two keys included. It ships with a right hand door swing (for the door to open from the left, add upgrade LHD). The door is self-closing to help protect stored items. The hospital grade cord includes a green dot plug for a more secure connection in wall outlets. For this same unit sized to fit under lower ADA compliant counters, see the VT65MLBIVAC456ADA. *NOTE: This unit's thermostat is pre-set for Celsius. If you prefer Fahrenheit, add complimentary option DTMEDF or let your sales representative know upon order. ABOUT NSF 456: NSF/ANSI 456 is a voluntary standard introduced in 2021 that was designed to establish the performance and construction requirements for vaccine refrigeration. Models certified to this standard undergo strict testing to confirm temperatury consistency. All Accucold units approved to NSF 456 for vaccine storage are certified by an independent testing agency.
