EN12975 Pre-heated solar water heater with copper coils 002A - SP-C

Pre-heated solar water heater

Work principle:

The water in water tank is for heat
preservation and circulation. The vacuum tube collector absorbs sunshine to heat
the water in water tank, when using the hot water, the cold water flows through
the inlet, the copper coil absorbs heat then transfer to the cold water, so that
temperature rise up ceaselessly, due to the original feature of the copper coil,
the water temperature of the outlet is close to the water temperature of water
tank(difference within 3 degree centigrade). Therefore, cold water flow via
copper coil and absorbs much heat, when water flow past outlet, the temperature
is usally hot enough to use.

7. Working temperature:-20~250 degree centigrade
8. Working pressure: 0.6 Mpa
9. Usual vacuum tube dimension: D47x1500mm/ D58*1800mm
10.Dual-purpose bracket for both flat and
sloping roof, and with different angle for different countries. Operation and
installation documents are free.

Application area:

Good solution for areas where
people have demand for good water qualityFor cold areas people have a large
demand for hot waterPlaces where there is daily needs of hot water

Feature:

1. It can withstand pressure of tap water when it works, and copper coil in tank bear
pressure.
2. Storage tank is used to heat water flowing through copper coil,
water absorbs much heat when flowing through the copper coil, hot water is
available immediately when you need.
3. High quality SUS304-2B stainless steel for water tank, processed by argon arc welding technique, under strict quality
control system, tank will never rust and leak.
4. High borosilicate all glass
vacuum tube has selective absorbing surface, absorptivity above 0.93 and
emissivity below 0.05, it enables vacuum tubes to have good absorb and transmit
performance.
5. Relevant accessories are optional instead of compulsory, client
can choose some or none according to actual need.
6. It can produce hot water with constant temperature.
7. Its indirect solar system, so water quality is superior, much cleaner than direct solar system.
8. Time of uploading water is cut, 24 hours water supply on condition that pipeline is working.
9. Life duration: 15 years, warranty: 5 years
10. CE, ISO9001
11. Lead time: 5-7 days for
a 20ft container, 10-15 days for a 40ft container
12. OEM,ODM offered.
13. To serve Europe, America, Africa clients better, at work in Europe work time
