Stored blood is sometimes indispensable for saving life. That’s why large quantities of human blood are stored in blood banks, together with numerous blood products derived from them. To retain their specific properties from the time they are donated to the time they are used they must be cooled. A special technology makes it possible to store organic material in nearly every desired temperature range from plus 4 degrees Celsius to minus 160 degrees Celsius. The cooling is no longer supplied by electrically powered compressors, but rather by gases from Messer.

The use of liquid nitrogen instead of compressors like the one in a refrigerator offers many advantages:

• No noise
• No waste heat
• Double or triple the storage capacity
• Up to 50% lower cost of energy, maintenance and repair
