Direct flow solar collector with assistant tank

Direct flow solar collector with assistant tank  consists of evacuated tubes , manifold and bracket. Evacuated tubes directly plug in the manifold and water between manifold and tubes are connected. So once evacuated tubes covert the solar power to heat the water in tubes ,the water of manifold will direct flow down to tube and push the hot water up to manifold.

Model of our direct flow solar collector: VNSC-AS1816CS-15T

Simple introduce:

Manifold : 180X160mm size with 15tubes design

Suggest hot heating capacity: 150L

Type: non-pressurized

Assistant tank size :24L

What's the details of direct flow solar collector?

l  Manifold: inner shell sus304 stainless steel 0.4mm;

outer shell:color steel .Size:180X160mm

Sharp: square

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

l  Tube: high efficiency three- target vacuum  tube

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

Characteristic:

l  Easy plug-in design and installation,open loop 

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.

What's the focus point of direct flow solar collector with assistant tank?

Assistant tank is design with float valve which can stopped the water  filling once system is full. The assistant tank size is designed with 24Liter which is much bigger than normal 5liters and 8liters, it is design for series connecting for direct flow solar collector. It can keep the overflow water from solar collector system and there is no overflow from system.
