A blood bank refrigerator is a specialized unit designed for safely storing blood and blood components at a consistent, low temperature of 2−6βC2 minus 6 raised to the composed with power cap C2−6βπΆ. Key features include precise microprocessor-based temperature control, advanced alarm systems for temperature deviations or power failures, and forced-air circulation for uniform cooling. These units have an inner chamber often made of stainless steel, outer construction of materials like M.S. or S.S., and safety features like lockable doors and internal drawers or shelves for organizing blood bags.
