Kewanee service
Service for the Kewanee boiler you already have.
Kewanee closed in 2002, but its firetube boilers still run in schools, plants, and buildings across California. Factory parts are hard to find, so owners need a company that can repair the pressure parts and tell them honestly when it’s time to replace.
McKenna services and repairs Kewanee boilers with its own crews. We don’t sell Kewanee equipment, so the recommendation is what the boiler needs: a repair, a retrofit, or a replacement when the numbers say so.

Why McKenna
Why plants use McKenna on their Kewanee boilers.
Independent
McKenna isn’t tied to a manufacturer’s rep agreement. We recommend what fits your plant, including keeping the boiler you have.
We build boilers
McKenna engineers and builds boilers in its own ASME code shop. That’s the same knowledge we bring to your Kewanee.
Code repairs in-house
McKenna holds the National Board R certificate, so welded tube repairs and other pressure part repairs don’t need another company.
One company for the boiler room
We service and repair other brands too. A plant with more than one brand of boiler gets one service company and one set of records.
