Non-Pressurized Erect-Plug Solar Collector Npc-58

The non-pressure solar collector is used for big application of hot water often in China. The cost of it is almost as half as heat pipe solar collector because there is no heat pipe and copper manifold inside.
It's suitable for commercial big project, such as hotel, community, school, ect...Automatic thermosyphon heat collection is prefferred water flows directly in the evacuated glass tubes connected to the mainfold.

Features:
1) working pressure less than 0.3mpa.
2) suitable for big projects where lowest ambient temperature is no less than -3. Degree.
3) vthermosyphon heat collectables is one of the shining points.
4)it uses vacuum tubes to heat water.
5)3) in large-scale projects, it can be installed on school, hotel, hospital

Specifications:
1) manifold(inner): SUS304-2B food grade stainless steel.
2) manifold(outer): Galvanized steel/stainless steel/color steel/aluminium alloy
3) vacuum tube sizes: Φ 47 x 1, 500; Φ 58 x 1, 800
4) Qty of tube: 10/15/20/25/20/30/40/50/60PCS
5) heat preservation layer: The 55mm machinery overall high pressure. Foamed polyurethane, has a good effect of temperature preservation.
6) hail resistant: 25mm
