Heat is conducted  through the heat-pipe without water in the vacuum tube.

The special frozen-proof technology guarantee the safe operation of this system under -50℃ circumstance..

The heat-pipe vacuum tubes can output energy in 2 minutes under sun due to the small heat capacity of heat-pipe.

The performance of selective absorption coating and vacuum insulation technology is prominent in winter.

Packaged in vacuum glass tube, the collector plate can have a long life performance without corrosion.

The collector of heat-pipe vacuum tube have a good performance in cold and heat shocking resistance and operate safely.
