How are the boilers packaged and shipped?

For metal products like boiler body, steam header, tank, etc, they will be packed by stretch film; for accessories, they will be packed in wooden cases or carton boxes. We can handle all shipments including standard container, open top container, flat container, bulk carrier, etc. Because of big dimensions, not all boilers can be loaded into standard containers. For gas/oil boilers, bigger than 5 ton/hr or 3.5 MW can't be loaded into standard container.

What documents are provided with the boiler?

Our documents include English instruction manuals, conformity certificate, drawings, manufacturing data, etc. More detailed documents can be provided upon request.

Is installation and commissioning support available?

We'll specify the service clause for installation and commissioning in details. Generally, our products can be handled by end-users themselves with our documents provided or internet online assistance. However, our service team members also are available for travelling upon request from customers.

AI-Powered supplier vetting

SummaryDevotion is identified as a boiler manufacturer rather than a professional technical supplier. It reports production capacity of 1,000 boiler sets, broad customization, 3D software design, ODM, and OEM services, plus new products during the past year. It holds multiple Chinese manufacturing and installation licenses and describes advanced fabrication/testing facilities, quality management, and an established sales and after-sales network. However, overseas service infrastructure is limited: no overseas warehouse, showroom, agent, or branch is reported, and overseas service coverage is stated as zero. Financial records are referenced for 2021–2023, but no figures or independent assessment are provided. Quality assurance and traceability status are unknown, testing equipment is reported as zero, and the sole listed R&D engineer mainly designs website and promotional materials.

Supplier typeThe supplier explicitly states that it is not a professional technical supplier, while its stated business is boiler manufacturing with annual productivity of 1,000 sets. Its company description also identifies it as a licensed boiler and pressure-vessel manufacturer.

CertificationsDevotion reports a Class B boiler manufacturing license, Class A steam generator manufacturing license, D1 and D2 pressure vessel manufacturing licenses, and a Class 2 boiler installation license. These are explicit sector-related licenses and support a positive certification assessment.

Production capacityAnnual productivity is stated as 1,000 boiler sets, supported by reported fabrication and testing facilities and multiple manufacturing licenses. However, the quality-control equipment count is reported as zero and quality assurance and traceability statuses are unknown, so production volume is evidenced but overall production-control capability is not fully established.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports 3D design, ODM, and OEM services, providing direct evidence of broad customization capability.
