300L Flat Plate Solar Water Heater

Flat Plate Collectors Solar Water Heater
300L Flat Plate Solar Water Heater

Feather of flat plate collector:
1. Special Anodized aluminum alloy frame to ensure handsome appearance and can accept high pressure without leakage.

2. Operation Temperature -33~120 degree.

3. Patterned temper glass or low iron temper glass (4mm thickness) is not easy broken with very high transmission and low emission Black chrome or Magnetic blue sputtering coating has very higher absorption rate to ensure the high efficiency.
