Johnson March Systems, Inc.

Company Overview

Johnson March Systems has been the global leader in providing custom Chemical Dosing, Ammonia Feed, and Steam and Water (SWAS) Sampling to the Power, Petrochemical, and Oil & Gas Industries since 1989. We differentiate ourselves with our ability to bid, design, and fabricate nearly every aspect of our projects. Johnson March is a certified ASME pressure vessel fabricator, and has a certified ISO 9001 Quality Assurance Program that separates our business from those that are less invested and able. In addition to being the company of choice for EPC’s and Engineering firms in the United States, Johnson March Systems has equipment in over eighty countries on six continents. The company’s roots reach back over seventy years with our original business being in dust suppression and dust collection. We thrive on projects that need a bit more engineering expertise and fabricating ability. We have the facility to handle the larger projects that others simply cannot.

Why Us?

The easy answer to this question is we are very good at what we do.  Our equipment is recognized as superior from a quality and longevity standpoint.  Because of our Engineering experience and Fabricating capabilities we are able to build truly custom equipment for the most detailed specifications.  We build more Sampling Panels and Chemical Dosing Systems in Shelters than any company in the world; frankly most of our competitors couldn't even lift the equipment we are often asked to build.   Having a certified ISO-9001 Quality Program is not merely to have a certificate to hang on the wall.  Being annually audited makes the process front of mind, this translates into a level of quality from project start to finish that sets us apart.  Customers come to us to have built the exact systems they want based upon their unique preferences.
