Premium Insulated Copper Pair Coils (Line Sets) For HVAC Systems OEM & Custom Sizes
Basic Properties
Trading Properties
Elevate your HVAC installation and repair projects with our high-performance Insulated Copper Pair Coils, also known as pre-insulated line sets. Manufactured in our own specialized facility since 2012, we are dedicated to producing superior quality copper tubing solutions for the global market, with a primary focus on meeting the stringent standards of the US, Australia, New Zealand, and Europe.
Our line sets feature two individual copper tubes—for refrigerant liquid and suction lines—pre-insulated together with high-quality white PE (Polyethylene) insulation. This factory-assembled design ensures consistent quality, saves installation time, and provides reliable thermal efficiency. We use 99.99% pure copper and premium insulation materials to guarantee durability, corrosion resistance, and optimal system performance.
We offer complete customization, including copper tube diameter, wall thickness, insulation thickness, and length. Furthermore, we provide comprehensive OEM services, including custom packaging with your logo and supplying necessary spare parts for installation. Trust us for reliable quality, timely delivery (15-30 days), and flexible solutions tailored to your business needs.

Our pre-insulated copper pair coils are essential components for efficient and reliable refrigerant transport in various systems:
-
Residential & Commercial HVAC: Installation of split-type air conditioners, heat pumps, and mini-split systems in new constructions and retrofit projects.
-
HVAC Repair & Maintenance: Ideal replacement line sets for servicing existing air conditioning units, ensuring a perfect match and quick installation.
-
International OEM Supply: Supplying HVAC manufacturers and large distributors in the US, Australian, New Zealand, and European markets with standards-compliant components.
-
Refrigeration Systems: Suitable for certain commercial refrigeration applications requiring reliable, pre-insulated refrigerant lines.
An HVAC line set forms the critical circulatory system between a condensing unit (outdoor) and an evaporator coil (indoor). It consists of two copper tubes:
-
The Smaller Liquid Line: Carries high-pressure, cooled liquid refrigerant from the condenser to the expansion device and evaporator inside.
-
The Larger Suction Line: Carries low-pressure, warmed refrigerant vapor from the evaporator back to the compressor in the condenser unit.
The white PE insulation sleeved over both tubes serves a vital function: it minimizes unwanted heat transfer (heat gain to the liquid line and heat loss from the suction line), ensuring system efficiency (high SEER/EER ratings) and preventing condensation and frost formation on the lines. Our factory-pre-insulated design ensures consistent, gap-free insulation coverage superior to field-assembled methods.
All copper tube coils are packed in standard export packaging to ensure safe transportation. We offer flexible shipping options to meet your requirements.
