PACIFIC DEF (Diesel Exhaust Fluid) Urea Solutions are produced by combining pure liquid urea from the urea process with clean plant steam condensate to produce the desired concentration. The resulting DEF solution is free of any chemical additives such as formaldehyde.

PACIFIC DEF is effective in controlling the emission of nitrogen oxides from stationary sources such as power plants as well as from diesel powered cars, trucks, trains, ships and heavy equipment. PACIFIC DEF is non-toxic, non-hazardous and formaldehyde free. It complies with AUS 32 and ISO 22241-1 specifications

Application Recommendation

PACIFIC DEF is marketed as ultra clean liquid fuel for catalytic abatement of nitrogen oxide emissions.

The decomposition of PACIFIC DEF into ammonia, carbon dioxide and steam provides a safe way to produce the ammonia fuel source. There is no need to have containers of compressed liquid ammonia in remote locations that are difficult to secure.

Transporation, Storage and Handling

  • The transport of PACIFIC DEF does not require a DOT placard.
  • PACIFIC DEF will decompose into ammonia, carbon dioxide at 275 °F (135 °C).
  • ALWAYS thoroughly wash vessels containing DEF before attempting repairs requiring welding.
