Collins CAMS IIA is a third-generation submarine analyzer, improving on more
than 40 years of successful CAMS fleet service. Our CAMS IIA uses mass
spectrometry and near infrared technology to monitor major atmospheric
constituents (H2O, CO2, N2, O2), common atmospheric contaminants (H2, CO) and
other components of interest (refrigerants and shipboard solvents). Collins CAMS
IIA is based on the same inherently reliable engineering approach that has given
our CAMS Mk I a documented operational availability of over 99 percent after
more than five million unit hours of operation by the U.S. Navy.
The Advanced Carbon Dioxide Removal Unit (ACRU) produced by Collins is the
first new CO2 technology since the inception of the nuclear submarine fleet in
1955. It has a 40 percent higher CO2 removal rate and lower energy consumption
within the same size requirements as the previous scrubber and burner units.
Collins ACRU uses a new solid amine system for CO2 removal that removes the
concerns of corrosion and maintenance associated with liquid amine in the older
systems, and it’s more environmentally friendly.
