1. High selective black chrome absorber
2. Advanced ultrasonic welding technology
3. Flat plate split solar collector
Key material of flat plate split solar collector (MRHG-1000)---black chrome:
---------------------------------------------------------------------------------------------------------------------------
Red copper full-surface absorber plated with black chrome. By using traditional plating technology, black chrome is plated on red copper with well heat-transfer performance. Black chrome, with steady physical characteristics, is a kind of selective coating which is absorptive to sun shortwave radiation.
