ABOUT US

LONGQUAN solar energy is China's largest export-oriented vacuum tube production base, the total exports more than 100 countries, and the annual production capacity of vacuum tube 10 million cigarettes. Accumulate 20 years vacuum tube production experience, concentrated 20 years specializing in the production process, exclusive launch"LONGQUAN thermostatic clean"coating process, to ensure that vacuum tube coating process stability, the effective protection of each root tube of the heat absorption effect. The production of vacuum tube efficient absorption solar light, realize rapid heating,

Superconductive heat tube

●   Common tube: Film layer metal bottom is aluminum, absorption layer and reducing reverse laver is nitrogen and aluminum ion compounds. Film total thickness is about 0.3 microns 

●  Three target tube: Three target tube membrane layer metal bottom is copper, absorption layer is nitrogen and aluminum ion reaction, and with a stainless steel components, reduce reverse laver is also aluminum nitride. Compared with common tube, because the emission rate of copper lower than aluminum, so three target tube has better heat preservation effec 

●  Zi Jin membrane tube: On the basis of the three tenors tube. When the Zi jin membrane tube coating reduced reverse layer deposition rate is much lower, relatively, coating time also is much longer(Membrane thickness is same. Because of film thickness and coating deposition rate to be proportional, time is inversely proportional). Reduced reverse layer of the aluminum nitride purer than three tenors tube, and relatively absorb is much better. 

●  Superconductive heat tube: It can be used all the year round. No matter in the south or the north, even at 40 degrees, this product can also operate normally. It avoids the ordinary solar energy water heater tube has the possibility of frost crack. Superconducting set thermal vacuum tube has three features: super heat absorption, super conduction and long life.

Heat transfer rapidly,special medium heat transfer speed is 1000 times more of copper heat conduction.

龙泉太阳能

Vacuum tube not leaking, not "scale.It also won't frost crack in-40'C low temperature.

这是描述信息

It can be connected with tap water directly, and can be pressure-bearing operate automatically(bearing capacity of 0.6 Mpa).

龙泉太阳能

It can be used normally in winter in the northern region on sunny days

龙泉太阳能

Set high thermal efficiency, by more than 20% than ordinary solar energy water heater ascension.

龙泉太阳能

Superconducting medium has low working pressure.When the temperature of summer tube wall up to 300C, it is not burst.

龙泉太阳能

If the individual valve damage.machine can still normal operation.It will never be flooded out.

龙泉太阳能

High-tech processing silicone seal ring is not easy to aging

 

LONGQUAN solar energy, the largest export-oriented crystal drill bladder production base of China, with 4 years crystal drill bladder and stainless steel bearing bladder export experience return inland. And the production of unconfined affordable crystal drill bladder has met European standards Comprehensive selection stainless steel, fundamentally avoid tank leaking,prolong the service life of the solar energy water heater Quality trustworthy!

In 2008, LONG QUAN spent 55 million Yuan respectively introduced automation ultra large solar enamel inner container of production line, automatic bearing stainless steel inner production line, automatic header port production line. And upgrading some original enamel production line. Especially we spent 31 million Yuan introduced China's largest solar energy water heater for enamel bladder production line, and has made professional three record: single enamel production line biggest investment; Manufacturing capacity maximum; Most manufacturing specifications (can produce 60 1- 600 I of the specifications of the enamel bladder)

Anti scaling: enamel coating imported special enamel powder, it is superfine particle. After the 870"C high temperature sintering, with enamel special high quality steel plate mutual fusion penetration Surface fine and smooth, scale not easy adherent. Prevent fouling, it can't release insalubrities or environmental pollution matter and can protect the water quality health.

这是描述信息

Corrosion resistance: crystal drill bladder acid (to the AAA level), alkali resistant, high temperature resistant, resistant to water vapor, resistance to penetration, not rust, corrosion resistance and high scale properties than ordinary solar water heater tank remarkable enhancement

这是描述信息

Insulation: crystal drill bladder surface enamel coating is the nonmetallic material. It has good electric insulation performance. And it can prevent leakage electric shock and can be efficient safeguard bath safety

这是描述信息

Long life: crystal drill bladder, select high-quality steel and imported special enamel powder, after 870C high temperature baking, form the enamel coating, and with steel plate mutual fusion penetration. Has a strong bonding force and stability. Elastic, tensile compression performance is good, effectively resist water fluctuating pressure and negative pressure, which can effectively avoid the tank suction dented accident happened, the service life lengthens 15 years

这是描述信息

Keep warm: enamel layer itself has superior heat preservation performance; In filled with boiling water, using hand directly carry enamel washbasin used in everyday life is not hot. It proves that enamel has superior heat preservation and heat insulation characteristics.

LONGQUAN introducing foreign lea ding solar energy technology, to develop a high qualitity plate type solar cllector Product outer frame is used construction level aluminums a lloy profiles. Outlook size can be customized according to customer demand.Core board using high thermal T2 copper. The optimization of the structure design and beautiful modeling, make it has excellent properties and good affinity, on behalf of the international advanced solar thermal utilization technology.
