    ® HemaCool Operating Instruction CHAPTER 1. INTRODUCTION Section I. System Familiarization 1-1. EQUIPMENT DESCRIPTION ® The HemaCool is a conventional liquid/vapor-phase refrigerator with a number of special enhancements: ® (1) HemaCool employs vacuum insulation panels to decrease the power required to regulate temperature in a given environment, to increase holdover time when energy sources are lost or disconnected, and to increase internal temperature stability.

  • Page 6: Features

    ® HemaCool Operating Instruction (b) In FREEZE mode (-22°C (-7°F)), the unit, provided its two internal 21 amp-hour batteries are properly charged, will keep blood products frozen for more than 8 hours, at an ambient temperature of 24°C (75°F). Freeze mode operation does, however, reduce the battery-powered hold time. (See Operational Specifications, Paragraph 1-4).
