Heat
collection is very fast. Its efficiency is over 10% higher
than normal all-glass vacuum tube.
No water in tube, so it successfully prevents the defects of
tube breakage and low power output caused by scaling and
deposits of dust and sand.
Low thermal capacity makes the tube start up quickly. Energy
output within only 2 minutes under sunlight.
High performance selective absorptive coating and vacuum
heat insulation technology ensure the tube still has high
heat efficiency in cloudy weather or in moist areas,
especially in winter.
Solar collecting plate is sealed in a high quality
borosilicate glass tube with 5 x 10 -3 Pa of vacuum, to
prevent from corrosion even in moist condition.
Ideal for pressurised solar thermal system (up to 0.6MPa).
System is reliable and simple.
