SABROE CAFP™ CO /ammonia freezers

SABROE CAFP™ CO /ammonia freezers
SABROE CAFP™ CO2 /ammonia freezers
Compact packaged freezer systems using reciprocating compressors,
and CO2 /ammonia as refrigerant, with a 100–800 kW capacity range
The highly customised 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.
These packaged systems are built around SABROE reciprocating compressors that
use CO2 as refrigerant, which gives them a significantly greater cooling capacity
than corresponding compressors using ammonia. This in turn makes the lowtemperature compressor much smaller, and the whole package significantly more
compact than traditional two-stage ammonia-based freezer systems.
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 ammoniabased two-stage or single-stage
systems with economisers, 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 twostage ammonia systems, and up to 45%
compared with single-stage set-ups.

Advantages
Benefits
Range
Compact design that fits inside a
standard 20-foot container
Big savings on installation costs
High COP and extremely low power
consumption, even at part load
Low operating costs
There are 6 standard models in
this range of freezer systems,
with capacities ranging from
87 kW to 793 kW.
Use of CO2 as low-temperature
refrigerant reduces piping complexity
and costs
Reduces installation costs
Very small ammonia charge, located
on the unit itself
No risk of ammonia leaks in
production areas, cold stores and
working areas
CO2 is a simple, inexpensive natural
refrigerant
Low operating costs
All CAFP units are operationally
tested with refrigerant before
dispatch. Factory acceptance
tests (FAT) available.
