Three Kinds of Coating Solutions of Aluminium Micro-channel Tube
Coating Material | Flux Coating | NOCOLOK Si Flux Coating | Zinc Coating |
Main Components | Flux(K1-3A1F46) | NOCLOK F1ux: 66.6% Silicon Powder: 33.3% Or according to customers requirements | |
Features | No need for extra brazing in brazing line but use aluminium fin material with a layer | The Si-flux to spray solder flux when brazing and the fin material can be bare foil | The tube with zinc-coated will highly enhance corrosion resistance performance |
Advantages of Silicon Flux Coated Aluminium Micro Channel Tube
Comparing with traditional aluminium tube, aluminium micro-channel tube with solder layer on the surface has a greater advantage:
1. Improve quality, enhance brazing, guarantee 100% brazing quality anti-corrosion, and environment-friendly.
2. Reduce cost: cheaper fin material replaces composite clad fin material, the thickness can be reduced up to 30%, reduce cost greatly, lower consumption of solder, fewer defects.
3. Working condition improvement: no flux particles in the air, reduction of effluent, and harmful gas sent out.
Micro-channel Technology in Heat Exchanger
1. Aluminium micro channel tube is the alternative solution to cooper tube and welded aluminium manifolds for increasing efficiency and reducing the overall cost.
2. Reduce your system refrigerant charge by as much as 35 %.
3. Improve your energy efficiency/coefficient of performance by up to 10 %.
4. Reduce your raw material consumption by more than 40 %.
5. Reduce your manufacturing cost compared to aluminium and copper heat exchangers.
6. Easily recycle.
