home solar water heater

high vacuum heating zijin tube the tsinghua university new AL - N/AL gradient coating technology, three target coating process, the absorption characteristic of stainless steel aluminum nitride layer, with ultra pure bronze mirror reflector, the production of high vacuum tubes has three advantages:
Mixer high-temperature absorbing layer stainless steel aluminum nitride, special high temperature resistant up to 500 ?, membrane layer does not fall off, not aging.
Mixer resistance to cold Ultra pure copper mirror, low reflection, small heat loss, alpine environment collection hot effect is good, still have hot water.
Efficient absorption of high absorption ratio 92%, reflecting lower than 65%, heat increased by 12%, the water temperature is higher, more hot water.
