1. High-efficiency heat insulation, reducing energy loss
Prevent condensation: The insulation layer effectively blocks the heat exchange between the copper tube and the outside world, prevents condensation and dripping on the tube wall, and protects the building structure.
Improve cooling/heating efficiency: Reduce heat loss of refrigerant during transmission, ensure efficient operation of the air-conditioning system, and reduce energy consumption.
2. Corrosion resistance & long life
Copper tube anti-oxidation: Copper itself is corrosion-resistant, not easy to rust, and not easy to leak after long-term use.
Anti-aging of the insulation layer: High-quality materials are UV-resistant and high-temperature-resistant, extending the service life.
3. Convenient installation & simple maintenance
Good flexibility: Copper tubes are easy to bend and adapt to complex wiring requirements (such as wall penetration and beam wrapping).
Integrated design: Some products are pre-installed with insulation layers to reduce on-site installation steps.
Convenient maintenance: If maintenance is required, the insulation layer can be removed and reused.
4. Anti-noise & safety protection
Reduce vibration noise: The insulation layer absorbs the vibration of the copper tube and reduces the noise during air conditioning operation.
Prevent scalding/freezing: In heating mode, the insulation layer prevents high-temperature copper tubes from being exposed and causing scalding; in cooling mode, it prevents frost on the low-temperature surface.
5. Environmental protection and energy saving
Reduce the risk of refrigerant leakage: Good sealing reduces the volatilization of refrigerants and meets environmental protection requirements.
Reduce electricity bills: Reduce energy loss and improve the energy efficiency ratio of air conditioners.
