Factory & Manufacturer Advantages:
1. State-of-the-Art PVD Coating Lines: Utilizing advanced, high-throughput magnetron sputtering systems for precise, uniform, and repeatable coating deposition.
2. Rigorous Quality Control: In-line optical monitoring (absorptance/emittance measurement), comprehensive adhesion testing, and accelerated aging labs ensure batch-to-batch consi
Packaging and logistics:
Application Scenarios:
1. Flat Plate Solar Collectors: Bonded to absorber plates (copper or aluminum) as the core heat-capturing element.
2. Evacuated Tube Collectors (ETC): Coated directly onto the inner heat pipe or U-pipe absorber fins/strips inside the vacuum tubes.
3. Unglazed Collectors (e.g., for Pool Heating): Applied to durable polymer or metal absorbers, leveraging low emittance for efficiency.
4. Concentrated Solar Thermal (CST) Receivers: (Higher-temperature grades) Used in parabolic trough or linear Fresnel receivers.
5. Industrial Process Heat (IPH): Enabling medium-temperature steam or hot water generation for manufacturing.
6. Solar Air Heating Systems: Coating absorber plates in air collectors.
7. Building-Integrated Solar Thermal (BIST): Integrated into facades or roofs where aesthetics and performance are critical.
International Certificates:
Standards Compliance: Meets or exceeds key requirements of ISO 22975-3, EN 12975 (durability tests), Solar Keymark (relevant aspects).
