CPI 184 Material Ring Success in Low Temperature BOG Compressors
CPI Gets Results
3-40X
Improved Lifetime
Challenge
BOG (Boil-Off Gas) Natural Gas is a very demanding application on the sealing components of a reciprocating compressor due to the extremely low 1st stage suction temperatures, together with the very dry (low-dewpoint, bone-dry) gas condition.

Solution Highlights
CPI, part of the Howden Group, installed one of our well-known dry gas material grades CPI 184, which has proved to be very successful in the BOG compressors, improving lifetimes by up to three years.
CPI 184 is a proprietary polymer alloy developed exclusively by CPI, which has become the preferred material for use on non-lubricated gas compressors and in particular those gases which are ‘bone-dry’ (very low dewpoint).
