Used for all returning loans, incoming new accessions, organic non-collections items (personal possessions) staff put in office areas as decoration; incoming non-collections materials such as wood, corrugated paperboad etc to that will go into collections areas | Features do not have but recommend: Alarm system for problems with temperature controls; External chart recorder (on the outside of the unit) •Points of caution: Double check rolling load capabilities with manufacturer. If freezing very heavy items and/or use of pallet jacks is anticipated, make sure the floor inside the freezer box is reinforced. NMAI had to retrofit one freezer with a ¼” – 3/16” aluminum diamond tread plate. • Ensure that controls are easily accessible. • If the freezer has heating strips around the door, make sure controls for these are accessible and will be turned off if the freezer is turned off or power goes out. Otherwise, if the heating strips are left on inadvertently while the freezer is off, the freezer box becomes a heating box, can cause damage to collections, and the heating strips will eventually burn out. |
