A medical blood bank refrigerator is a specialized, high-performance medical device designed for the safe, long-term storage and preservation of blood products, including whole blood, red blood cells, plasma, and other blood components. Unlike domestic or commercial fridges, they are engineered to maintain a precise,, consistent temperature, typically between +2°C and +6°C (often set at 4°C), to prevent hemolysis (rupturing of blood cells) and ensure the viability of blood for transfusion
