solar keymark collector

5) hail resistance:15mm

4)heat preservation: 72 hours

3)glass tube dimension:47X1500 mm

2) outer manifold: VPDF

1) inner manifold:stainless steel SUS304 2b,

Specification;

e)Endures climate feature:thermal effiency is goos in the whole year,

d)long performance life: 15 years

c)Magnetism accuse of alternative absorption coating,AL/N/AL of sputter aluminum nitrogen aluminum alternative absorptation coating solar radition absorption rate>92%,and hot emittance<7%,

b)double-deck glass coaxical structure, intermediate layer releases the vacuum,maintains 5X10-2Pa high vacuum for a long time while in charge

a)adopts the double-deck highly special hard glass tube of boron silicon

5) working principle of low pressure solar heate: it adopts the alternative absorptiobsorption coating absorb the solar energy,heat the water in the vacuum tube directly,through the cold and hot water convection,changes the solar energy into heat energy to store in the water tank:

4)inlet water hole connects to the tap water,and the outlet hole connects to the tap water,and the outlet hole produces pressure hot water directly,

3) can be put in the courttard, on the roof or balcony,

2)Easy to use and convenient to install,

1) working principle of high pressure solar heater:it utilizes the alternative absorption coating on the inner surface of the vacuum tube,from the high-temperature environment super-conduction tubes,leads the heat to the water tank,and produces hot water,
