non-pressurized solar water heater glass panel 

Non-pressurized solar water heater glass panel is the third generator of solar collector. Its absorbing core are composed by different numbers of  evacuated tubes.The more evacuated tubes equiped,the more heating ability it becomes.And evacuated tubes are made by high borosilicate glass which is high temperature resistant. non-pressurized solar water heater glass panel works in natural circulation. The tubes are installed in both side of the manifold.Tube water will exchange with manifold cold water by passive way.And hot water will go up to the top side of manifold and ready for the another exchange with outside device. 

Model: VNSC-1816S2-50T

Here is a simple introduce of our solar water heater glass panel for your study.

Manifold : double way each 25pc tubes

Suggest capacity: 500L

Type: open loop

Working in series for big hot water system more than 500L

We focus  a lot  on our details.

l  Manifold: inner shell sus304 stainless steel 0.4mm;

outer shell: 201 stainless steel.Size:180X160mm

Sharp: square

l  Frame: 1.2mm stainless steel ,strong resistant to the wind

l  Tube: high efficiency three target coating tube which higher effeciency than single target coating tube, weight more than 2kgs

l  Insulation:40mm high density 38kg/m3, smooth and nice looking

l  Double wing design ,can be 40tubes,60tubes

Characteristic:

l  Easy plug-in design and installation.

l  Optional frame angle can resists wind with a velocity of 36m/s.

l  Can supply hot water to large amount water needed.

l  Economical for hotel, school, dormitory, hospital and commercial building.

 How to making a solar water heater project with solar water heater glass panel?

To make a solar water heater, we can combinate solar water heater glass panel ,non-pressurized solar water heater tank ,controller and other components such as pipeline,valves ,fittings. If it is big capacity system more than 1000L, i suggest to do the active working for the solar water heater system for exchange heat sufficiently. We set the heat exchange temperature differece valve between solar water heater glass panel and solar water heater tank,once it reaches the valve,circulation pump with be actived .The system works.More details,please contact us for details with your detail information of project.
