5 years warranty Non-pressure solar collector manifold for hotel ,school ,comercial hot water heating project 

 

 

1. What is the advantage of non pressure solar collector ?

 

 

 

Compared with  pressure heat pipe solar collector , the non pressure solar collector is much less expensive than that . because it is made up by solar glass vacuum tubes and water will go through the vacuum tubes .

 

Non pressure solar collector are widely used in solar hot water comercial project ,such as for hotel , school or factory central hot water supplying system .

 

 

2. working principle of non pressure solar collector

 

 

 

The non pressure solar collector works same way as the non pressure solar water heater . water go through vacuum tubes ,and vacuum tubes will heat the water and hot water go to top and cold water go down . the hot water will go out from the manifold .

 

3. the sturcture of non pressure solar collector

 

The non pressure solar collector include 3 parts . solar vacuum tube , manifold and stand bracket support .

 

There are two type of soalr collector ,one type is vertical type (one side open manifold ) ,and another type is horizontal type (both side open manifold for vacuum tubes )
