Introduction


IntroductionDemister.gif (20574 bytes)

Koch-Otto York were once separate companies competing in the mist eliminator equipment manufacturing and supply business.

The term Demister® is actually a registered trademark of the Otto H. York Company, Inc. but due to the original success and popularity of their mist eliminator products, the term Demister® has been mistakenly taken as a generic term for all mist eliminator products.
