The Sabroe CO2/Ammonia Freeze Package (CAFP) concept combines the advantages of CO2 on the low-temperature side and ammonia on the high-temperature side.
A CO2 compressor has a capacity 8 to 12 times greater than a similar ammonia unit, making the low-temperature compressor much smaller, and the whole unit significantly more compact.
CO2/Ammonia Freeze Package (CAFP) equipment is available with capacities of 100-800 kW.
