Could operate in very cold days, even under -30℃ambient temperature.

Fast system starting and rapid thermal conductivity in winter time.

Season independent operation thanks to the anti-freezing heat transfer medium.

Larger heat transfer end and wider copper pipe for faster heat transfer and higher efficiency. 

European Solar Keymark certified, with satisfactory annual energy yield.

Could work smoothly with high efficiency in winter days, even under -30℃。

Both the φ24 andφ14 heat transfer end are available. 

Solar water heater for household application, certified by European Solar Keymark, widely installed in Europe, Middle East, South America, Africa, including the thermosiphon solar water heater, both the vacuum tube type and the flat plate type, both the non-pressurized system and pressurized system.

Solar collectors, certified by European Solar Keymark, both the vacuum tube type and flat plate type, including CPC U-pipe solar collector, heat pipe solar collector and flat plate solar collector, widely installed worldwide for the water heating, industrial process heating, district heating in winter time, solar cooling, etc, for hotels, factories, public works, office buildings, etc.   With total German technology, the CPC U-pipe solar collector could even supply the hot water up to 150℃。

Could be used for high temperature solar thermal applications, heating the water up to 130℃， suitable for the industrial process heating, hotels, hospitals, solar cooling, steam, etc.

The CPC U-pipe solar collector is certified by European Solar Keymark, with satisfactory annual energy yield, meanwhile the heat loss is much less.

The energy yield is comparatively higher in the cloudy and winter days, compared to other types of collectors, due to the equipment of the European CPC reflector, thus reducing the application of the backup traditional energy.

Short installation time due to the complete pre-assembly.

Equipped with European CPC reflector and U-shape copper pipe. 

Certified by European Solar Keymark, with satisfactory annual energy yield. 

Could heat the water up to 130℃.

Higher efficiency while lower heat loss. 

Better performance in cloudy and winter days
