CAFP unit

CO2 /Ammonia Freeze Package

Compact packaged freezer systems using reciprocating compressors, and CO₂ /ammonia as refrigerant, with a 100–800 kW capacity range


The highly customized Sabroe CAFP freezer systems are based on a cascade system that combines the advantages of CO₂ on the low-temperature side and ammonia on the high-temperature side.

As a result, each standard CAFP package can be fitted inside a standard 20-foot shipping container, if required. This does away with the need for a special machinery space, and the freezer installation can easily be moved if required.

Compared with conventional ammonia-based two-stage or single-stage systems with economizers, a CAFP unit uses significantly less power in the temperature range down to –55°C. This results in energy savings of as much as 15% compared with traditional two-stage ammonia systems, and up to 45% compared with single-stage set-ups.
