Imperial Brown® is one of the world’s top manufacturers of custom walk-in coolers and freezers.
Imperial Walk-in Coolers was started in Portland in 1970 by Al Zell to serve the commercial refrigeration industry by manufacturing the insulated panels used to build walk-in coolers and freezers.
In 2012, Imperial Manufacturing of Portland, OR, acquired W.A. Brown & Son of Salisbury, NC, a 100-year-old walk-in cooler manufacturer, to form Imperial Brown. In a four-year period, the North Carolina plant grew from 40 employees to 130, with a $15 million increase in revenue.
In 2017, Imperial Brown acquired a third manufacturing facility located in Prague, OK, with plans to invest more than $1.5 million in new equipment in the plant within the initial two-year period of ownership.
