DCL Marks 40 Years of Catalytic Innovation

TORONTO, Sept. 29, 2026 /CourierPR/ -- DCL International Inc., a global leader in advanced catalytic technologies, marks its 40th anniversary with the launch of a refreshed brand identity that honors the company’s heritage while reflecting its evolution and continued growth. The company, now part of the DCL Technology Group, has grown as a family business built around the belief that hard problems are worth solving, and cleaner air, better technology, and greater industry sustainability are worth pursuing. Founded in 1986 as Diesel Controls Limited, DCL began by developing emissions-control technologies for diesel vehicles operating in underground mines. Since then, the company has expanded its capabilities, geographic reach, and applications to become a global provider of advanced technologies that reduce emissions, support cleaner energy, and improve industrial efficiency.

Since then, the company has expanded its capabilities, geographic reach, and applications to become a global provider of advanced technologies that reduce emissions, support cleaner energy, and improve industrial efficiency.

What started with underground mining emissions has grown into a group of companies serving industries around the world, from power generation and data centers to clean fuels, aerospace, and food sustainability. DCL has also expanded its manufacturing operations in Canada and the United States, established a European presence in Germany, and launched companies addressing emerging needs in trucking, emissions control, and renewable energy.

The company’s new visual identity reflects that evolution. DCL’s original logo featured the representation of a mine entrance, reflecting the industry in which the company began. The redesigned logo retains that meaningful symbol while reimagining it for a broader, more forward-looking story.

Throughout its history, DCL has continued to expand its technical and manufacturing capabilities. Milestones include developing early diesel particulate filters for mining vehicles; entering stationary engine and alternative-fuel markets; expanding into catalyst coating, metal substrate manufacturing, and high-temperature vacuum brazing; and advancing technologies for methane reduction, natural gas decarbonization, hydrogen electrolysis, and specialty catalyst applications.

DCL’s growth has also led to the creation and expansion of businesses within the DCL Technology Group, including Roadwarrior, GraniteFuel Engineering, and AERINOX. Together, the group’s companies apply engineering and technology to help customers reduce emissions, recover and reuse energy, transform waste streams, and operate more sustainably. The DCL Technology Group now employs more than 400 people across multiple industrial sectors and maintains an international presence serving customers around the world.
