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 air conditioning (ACR) systems use pancake copper coils?

Absolutely not. ACR-grade copper tubes undergo special degreasing and internal drying during production, and are sealed with nitrogen to ensure no moisture, oil, or dust inside the tube. Ordinary water pipes may contain residues, which will contaminate the refrigerant and damage the compressor once entering the air conditioning system.

Q:Why is copper purity (C12200) so important?

C12200 (Phosphorus Deoxidized Copper) usually has a purity of over 99.9%. High purity ensures excellent thermal conductivity and prevents cracks during bending and flaring. Low-quality copper tubes (high impurities) are prone to electrochemical corrosion and refrigerant leakage.

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

It depends on the cooling capacity (tonnage or HP) of the system. 1HP -1.5HP (9k-12k BTU): Usually equipped with 1/4'(6.35mm) liquid tube and 3/8'(9.52mm) gas tube. 2HP - 3HP (18k-24k BTU): Usually equipped with 1/4' or 3/8'liquid tube and 1/2'(12.7mm) or 5/8'(15.88mm) gas tube. Recommendation: Always refer to the equipment manufacturer's service manual.

Q:If the plastic caps on the tube ends are missing upon receipt, can the tubes still be used?

Use with caution. Plastic caps maintain internal nitrogen pressure and cleanliness. If the seal fails, moisture may have entered the tube. It is recommended to purge with dry nitrogen before installation and check for obvious oxidation or impurities inside.

Q:What are the available outer diameter sizes?

Available sizes include 1/4, 5/16, 3/8, 1/2, 5/8, 3/4, and 7/8 inches.
