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:Why must HVAC and AC systems use pancake copper coils instead of ordinary water pipes?

ACR-grade tubes are specially degreased, dried, and nitrogen-sealed to ensure no moisture, oil, or dust. Ordinary water pipes may contain residues that contaminate refrigerant and damage the compressor.

Q:Why is C12200 copper purity important for these pipes?

C12200 has over 99.9% purity, ensuring excellent thermal conductivity and preventing cracks during bending. Low-quality copper with high impurities is prone to electrochemical corrosion and leakage.

Q:How to choose the correct tube diameter for air conditioning capacity?

It depends on cooling capacity. 1HP-1.5HP usually uses 1/4' liquid and 3/8' gas tubes. 2HP-3HP uses 1/4' or 3/8' liquid and 1/2' or 5/8' gas tubes. Always refer to the manufacturer's manual.

Q:Can tubes be used if plastic caps are missing upon receipt?

Use with caution. Missing caps may allow moisture entry. It is recommended to purge with dry nitrogen before installation and check for oxidation or impurities inside.

Q:What are the main applications for this copper pipe?

Primarily used for HVAC Systems and Refrigeration applications, including air conditioning units and refrigeration equipment.
