Product Description

Description

Insulated Copper Tube Pair Coils

Nexnice Insulated Copper Tube series combines 99.96%pure phosphorus-deoxidized copper with advanced insulation. Designed to reduce installation time by over 50%, it ensures zero condensation and a service life of up to 70 years.

Craftsmanship:
* Annealing (O Temper): Copper is soft-annealed to ensure maximum flexibility for hand-bending without kinking.
* Internal Cleanliness: Tubes are processed to exceed international cleanliness standards, ensuring no contaminants interfere with
sensitive refrigeration components.

Feature

* High-Pressure Compatible:Specifically designed for R410A and R32 refrigerants.
*Condensation Prevention:High vapor barrier prevents moisture buildup and structural rot .

*Ready to Install:Tubes are cleaned inside at the factory and fitted with dust caps.

3-Layer Advanced Insulation:

*Outer: Embossed PE film(UV composite, tested to AS 1530.3 fire standards).
*Middle: Electronic bridge foaming (heat/cold/impact resistant).
*Inner: Nitrile rubber or independent closed cells for thermal barriers.

Product Details

Product Advantages

* Energy Efficiency: Low thermal conductivity (0.032 to 0.043 W/m.K) keeps refrigerants at optimal temperatures, reducing compressor load.
 * Microgroove Technology: Some advanced tubes move heat 10-15% more efficiently and use up to 40% less refrigerant.
* Durability: Service life of 50-70 years; naturally antimicrobial to prevent biofilm and mold.
* Condensation Prevention: High vapor barrier (<10,000μ) stops sweating and subsequent water damage to buildings.

Industry Standards and Certifications

 * Refrigeration/AC Standards: AS/NZS 1571 (AU/NZ), ASTM B280 (USA), BS EN 12735 (EU).
 * Fire Performance: AS 1530.3 (Standard for ignitability, flame propagation, and smoke release).
 * Insulation Standards: AS/NZS 4859.1, ASTM E84-21a.
 * Safety: AS 1677 (Refrigerating systems safety).
 * Quality: ISO 9001 certified manufacturing processes.

 Required Qualifications

 * Professional Installation: In most regions (e.g., Australia), installation is NOT DIY. It requires a licensed HVAC technician.
 * Refrigerant Handling: Technicians must hold relevant licenses (e.g., ARCTICK) to legally handle and charge refrigerants like R32 or R410A.
 * Brazing Certification: Specialized qualifications may be required for structural brazing in commercial settings.

Comparison with Other Materials

Dimension	Insulated Copper Tube Pair Coil	Insulated Copper Tube Single Coil
Installation	Insulated Copper Tube Single Coil	Two separate runs (vapor line insulated, liquid line bare) require more labor and two penetrations
Material Cost	Higher per foot due to bundling	Lower if buying standard copper and insulation separately
Leak Detection	Difficult – lines are wrapped together, must unwrap to identify the leaking tube	Easier – insulation can be cut locally to access and inspect the single tube
Wear & Failure Risk	Moderate – tubes can rub against each other from vibration, causing pinhole leaks over time	Low – no internal rubbing; only risk is against hangers, which can be padded
Best Suited For	Standard split systems where speed and aesthetics matter	Mini-splits, refrigeration, high-efficiency builds, or repairing only one line

FAQ

Q1: What parameters should be provided for an RFQ (Request for Quote)?

Please provide specific details: Outer diameter (OD) & wall thickness, coil length, insulation thickness, outer material type, as well as any fire rating or custom logo requirements. The more detailed the information, the faster the quotation.

Q2: Do you support customization?

Yes, we offer comprehensive customization: Product Specifications: Length, outer diameter, wall thickness, material, and color. Materials/Colors: For example, black rubber insulation or custom film colors. Branding/Packaging: Customized products, cartons, labels, logos, and internal support pillars for the secure transport of HVAC/R equipment.

Q3: How do you ensure product quality?

We implement strict quality control from raw materials to final inspection. We provide real-time photos or videos of the production → packaging → loading process to ensure full traceability.

Q4: How can I get new product update information?

Answer: We will promptly send you the latest promotional posters! You just need to share your contact information with us.
