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 8–12 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 80–400 kW at -50°C or 140–650 kW at -40°C.
