Manifold non-pressurized solar heat collector

Manifold non-pressurized solar heat collector is popular used for  big project such as more than 1000L .It is used for open loop solar water heater system.Evacuated tubes are assembled as the heat generator. This generator fetches the heat energy from solar  and transfer the heat energy to heat the water in tubes.Manifold is a bufferly storage tank temporarity. With long time absorbing and transfer,the manifold can not storage too much energy,a storage big tank is requested. Usually this solar heat collector system has two working way: passive circulation working and active circulation working.  Passive circulation working requests the storage big tank placed above the solar heat collector for thermosiphon work. But active circulation working is not strictly on installing position.

Model: VNSC-T1816S3-25T

Working way: non-pressurized ,open loop,working pressure 0

Internal material :316L top quality stainless steel 

external material :SUS304-2B stainless steel 

Support in Aluminum alloy with 304 bolts and screw

Following is the detail describtion on our manifold non-pressurized solar heater collector.

l  Manifold:

inner shell: 316L stainless steel 0.4mm;

outer shell: SUS304-2B stainless steel 0.31mm

 Sharp size :180X160mm square

l  Support Bracket:1.8mm aluminum alloy ,Multi-installation design for slop and stand roof

l   Tube: high efficiency triple target tube, thickness 1.6mm glass for strong against delivery impact, weight more than 2kgs higher than market standard

l  Heat preservation layer: high density polyurethane 40mm,equil foaming density and smooth appearance

What's this manifold  non-pressurized solar heat collector advantage?

l  Inner material 316L ,the best quality against bad water quality .It is the best quality of the stainless steel for inner tank.

l  Outer material: SUS304-2B food grade against chemical environment,anti-rust feature for long lifetime.

l   Support frame in aluminum alloy also against chemical environment.

     The design with multi-functional for flat and slop roof makes installation easy for different situations.

Frame of solar heat collector with adjustable tube holder makes easy installation of tube.

l  Inlet and outlet 1’’  size fits for commercial hot water system. The bigger capacity system would request bigger fitting size more than 1''.

l  Arc-argon technical is applied to welding inlet and outlet ,no hurt to inner steel.

l  It can be used for sea island situation cause of top materials applied.
