DCL International Inc.

Oil and gas engine-duty exhaust control starts with parts that keep diesel engines inside emissions limits. At DCL International Inc., we build catalytic converters and diesel exhaust purifiers from Concord, Ontario.

We began with underground mining vehicles and still carry that emissions focus into OEM programs, retrofit packages, and industrial engine applications.

Our shop manufactures metal substrate components and uses high-temperature vacuum brazing on those parts. That capability supports exhaust packages where heat, duty cycle, and engine fit have to be solved before the unit goes back into operation.
