Our History

McFarlen Engineering Ltd. was founded in 1990, when Jonn McFarlen decided to resign his full-time position and implement his revolutionary ideas through starting his own consulting engineering practice. Jonn’s vision was not to build just another engineering consulting firm. His main focus has always been on the Recausticizing system with a goal to provide a comprehensive engineering solution through combining consulting services with innovative parts and equipment solutions – improving recausticizing and material handling operations.

For over 26 years, McFarlen Engineering Ltd. has been saving millions of dollars by increasing reliability for hundreds of clients in Pulp and Paper, Waste and Water Treatment, Mining and Food Processing industries. Today McFarlen Engineering Ltd. is well known in the recausticizing community as a leading provider of recausticizing, clarification and filtration systems.

McFarlen Engineering stocks support tubes and GORE® Membrane Filter Socks for pressure filters as well as caulking cord in its Vancouver warehouse for quick delivery to its customers.

In many cases the equipment and parts have been custom designed to improve performance over that supplied by the original equipment manufacturer (OEM).

Please keep McFarlen Engineering in mind whenever you are looking to upgrade or improve the performance of your recaust plant or clarification/filtration system.
