What Comes With Each Refurbished Boiler

When you buy a used boiler from Cole Industrial, you aren’t buying a mystery. You are buying a certified asset backed by data.

Inspection Reports and Service History

Transparency is key. We provide copies of our internal inspection reports, detailing the condition of the vessel, tubes, and refractory. If we have the original manufacturer’s data report (U-1A), that is included as well. You will know exactly what you are getting before the truck arrives.

Warranty Options

We stand behind our work. Our standard refurbished boiler packages typically include a warranty on the parts we have replaced or refurbished. This gives you confidence that the equipment will perform as expected.

Testing and Certification Results

Every refurbished boiler undergoes a hydrostatic pressure test to 1.5 times its design pressure to confirm vessel integrity. We also perform a fired test (when possible) or a full simulation of the control system to verify safety interlocks. These test results are documented and provided to you.

Optional Upgrades (Controls, Burners, Efficiency Enhancements)

A used boiler purchase can be an opportunity to align the unit with your current operational needs. Depending on the configuration and condition of the boiler, certain upgrades may be available prior to shipment. 

In some cases, controls can be modernized or adjusted to better match your facility’s requirements. Fuel train modifications or burner adjustments may also be possible to align with site utilities or emissions considerations. Availability of upgrades depends on the specific unit and application.
