    The FARRAR ULC Series meets these requirements. These units are forced-air, low-temperature, long-term storage freezers with built-in redundancy. Interior chamber temperatures are maintained between +2°C to +8°C and -20°C to -80°C. The ULC Series chamber consists of two redundant cascade refrigeration systems.

  • Page 5: Blower

    Blower The blower produces a forced air flow of 500 cfm, with an air change every two seconds. This forced convection moves energy from the container surface to the air. The resulting air circulation moves the energy to the evaporator coil, which then moves to the evaporator and achieves equilibrium.

  • Page 6: Alarms

    The ULC Series internal blower will automatically turn off when either of the two exterior doors are opened. When one of the two exterior doors is opened, the LCD screen displays a warning icon, along with a yellow light indicator on the light bar located in the top middle of both doors.
