High Pressure CO2 Absorber

CEPEDA designed this unit to remove carbon dioxide (CO2) from high-pressure air.  This unit is classified as a LEVEL I/SUBSAFE component by the U.S. Navy. We have manufactured, tested, and serviced these units for many years.

The absorber showcases most of CEPEDA’s capabilities requiring the best machining, welding, and NDT that we offer.
