?:definition
  • Laboratory freezers designed to prevent ignition of flammable materials (vapors and/or gases) at temperatures from 0 to -20 or -30 degrees Celsius (32 to -4 or -22 degrees Fahrenheit); flammable materials may be present in the environment outside the freezer or the result of vapors leaking from improperly sealed containers inside the freezer. These freezers usually have motors, switches, and thermostats that are insulated to prevent arcing that can ignite flammable air-vapor mixtures; insulation prevents explosions inside and/or outside of the unit. All explosion-proof freezers must be hardwired directly to the power source by rigid metal wires rather than connected by cord-and-plug assemblies. Explosion-proof laboratory freezers are used in rooms in which a flammable atmosphere may develop. They are mainly available in upright and undercounter configurations.
