Monoethanolamine (MEA) Scrubbers

For more than 40 years, CEPEDA has designed, manufactured, tested, serviced, and refurbished carbon dioxide (CO2) scrubbers for the U.S. Navy. These units utilize monoethanolamine (MEA) to remove CO2 from enclosed atmospheres.

The scrubbers are a staple of CEPEDA's product line that showcase the following capabilities:

Machining

  • CNC-milled components

Fabrication

  • Piping

  • Complex layouts

  • Large rolled shells

  • Spun tank heads

Welding

  • GTAW

  • SMAW

  • Consumable inserts

  • Pipe socket welding (Tech Pub 278 classes P-1 & P-2)

  • Pipe socket brazing (NAVSEA 0900-LP-001-7000 class P-2b)

  • Materials include various stainless steels and aluminum

NDT

  • Visual inspection (VT)

  • Liquid penetrant (PT)

  • Hydrostatic pressure testing

Testing

  • Pressure testing

  • Operational testing

  • Acoustic testing

Lithium Hydroxide (Li-OH) Scrubbers

For over 20 years, CEPEDA has manufactured, tested, and serviced lithium hydroxide (Li-OH) scrubber receptacles (hoppers) for the U.S. Navy. These units draw contaminated air through Li-OH canisters to remove CO2 and other harmful contaminants from enclosed atmospheres.

The hoppers have become a staple of CEPEDA's product line since we initially reverse-engineered them for the U.S. Navy. They showcase the following capabilities:

Machining

  • CNC-lathe components

Fabrication

  • Sheet metal

  • Complex layouts

  • Precise fit-ups

Welding

  • GTAW

  • Materials include various stainless steels

NDT

  • Visual inspection (VT)

Testing

  • Operational testing
