CO2 (R744) Cascade Systems

Using CO2 (R744) in cascade systems gives a number of advantages:

• 1

  Efficiency of the system is high even in the hot climates

• 2

  Only a small amount of refrigerant is needed for high temperature stage

• 3

  Temperature difference for cascade heat exchanger is relatively low

• 4

  On the high side various refrigerants can be used ex HC/HFC or NH3.

• 5

  Lower First Cost

• 6

  Less space required

• 7

  Lower temperatures at reasonable costs

• 8

  CO2 (R744) is non-toxic and non-flammable

• 9

  CO2 (R744) does not damage products

• 10

  CO2 (R744) Cascade Systems reduce CO2 (R744) emission
