AI-Powered supplier vetting

SummaryThe supplier is presented as a professional technical HVAC/R supplier with production lines, moulds, patents, and a complete HVAC/R product range. It reports ISO 9000 and ISO 9001 management-system certifications and states that most products hold CE, RoHS, and UL approvals. Customization is available from samples and designs, including full, minor, and flexible customization. However, the supplier does not provide 3D software design, ODM, SDK, or well-known-brand OEM services, and launched no new products in the past year. It has no overseas warehouse, showroom, agent or branch, and has not participated in offline trade shows. Service quality assurance is stated, but complaint handling and corrective-action arrangements are described only as “Others.” Financial records are referenced for 2022–2024, but no financial performance details are provided. No specific customer cases are identified.

Supplier typeThe supplier is explicitly identified as a professional technical supplier and describes a complete HVAC/R range with production lines, moulds, patents, and one-stop solutions. Its stated business scope also covers hardware, building materials, mechanical equipment, refrigeration and air-conditioning equipment, and related technical services.

CertificationsThe supplier reports ISO 9000 and ISO 9001 management-system certifications. It also states that most products are approved by CE, RoHS, and UL, although the evidence does not indicate that every product holds these approvals.

R&D capabilityThe supplier has R&D capability, patents, and states that it continues to innovate and improve technology. Conversely, it launched no new products in the past year and does not provide ODM, SDK, or 3D software design services, indicating some limitations in documented innovation-service breadth.

Production capacityThe supplier states that it owns a series of production lines and moulds and provides a complete HVAC/R product range. Its business scope includes sales of refrigeration and air-conditioning equipment and related industrial products, supporting production-related capability, although no capacity or output figures are given.

Customization capabilityThe supplier explicitly offers customization from samples and designs, as well as full, minor, and flexible customization. This supports a broad customization offering, but 3D software design is not available.

Product Q&A

Q:Is this duct insulated?

No. The ALU Series is an uninsulated flexible duct designed for applications where thermal insulation and condensation control are not required.

Q:What is the difference between ALU 2.0, ALU 3.0 and ALU 6.0?

ALU 2.0 is the lightweight economical version, ALU 3.0 offers balanced strength and cost, and ALU 6.0 uses a reinforced multilayer structure for higher pressure requirements.

Q:What is the maximum operating pressure?

ALU 2.0: 2500 Pa; ALU 3.0: 3000 Pa; ALU 6.0: 3500 Pa.

Q:What sizes and lengths are available?

Standard diameters range from 85 to 508 mm (3-20 inches), with a standard length of 10 m. Customized lengths are available upon request.

Q:How should the flexible duct be installed?

Extend the duct as fully as practical, seal connections with suitable aluminum foil tape, secure them mechanically with clamps, and avoid sharp bends or excessive sagging.
