This system consists five parts: solar collector, work station, expansion vessel, pressurized tank and controller.
This system provides many advantages. It is the simplest and typically the least expensive active system to install. There is no heat exchanger, which allows efficient heat transfer directly to the water.
The system operates at a standard line pressure. It is simple to add capacity to the system if demand changes. The system integrates easily with exsiting system.
Solar heating system
1) once heat-exchange system
2)twice heat-exchange system ( single copper coil )
3) twice heat-exchange system ( double copper coil )
Products are put into cartons firstly. The samples are loaded into the plywood boxes. For the fcl goods, cartons can be loaded into the container directly.

Thermo siphon solar collectors provides mains pressure pre-heating via a high efficiency copper coil heat exchanger located within the solar collector tank. The way in which the Mains Pressure solar collector heats water is the same as the Non pressure solar collector. Rather than using the water in the tank directly, as the Non pressure does, the type uses a 45óª60 copper coil heat exchanger inside the tank which provides more than 1.2m2 of heat transfer area. When water flows though the coil it absorbs heat from the water inside the solar collector tank. The solar collector tank is therefore a thermal store. One advantage of this system is that almost no water is introduced into the tank apart from occasional topping up), so corrosion and scale buildup are almost totally eliminated. Tanks are designed for low to medium pressure applications using a gravity feed tank or pressure reduction valve. Direct connection to mains pressure water supply is not permitted.
The heat collectors and the water tanks are connected perfectly, the heat which the panels collected will be stored in the water tank, it guarantees 24 hours per day to provide the hot water, and the system can work even under the -30 degrees. It can supply with a few tons even more water, is an ideal hot water supply system. It is applied to the big hotels, restaurants and other large places.
1: The water tank should be placed higher than the heat collectors, while the models are isolated types and the heat collectors are not pressure-enduring; The water recycled freely by the height difference between the water tank and the heat collectors.
2: The water tank should be placed lower than the heat collectors, while the models are isolated types and the heat collectors are pressure-enduring, the water is recycled by the water pump between the water tank and the heat collectors, the specific pressure-enduring models, please see the information of the pressure-enduring models on the web.
Compact pressurized solar water heater work with heat pipe:
1. The material of inner tank is SUS304 2B (food grade) with 1.2mm thickness. All machine welding.
2. The material of outer tank is SUS304 2B with 0.4mm thickness.
4. The material of stand frame is stainless steel with 1.2mm thickness or Aluminum alloy with 2.0 thickness.
5. The thickness of polyurethane foam is 55-60mm.
6. It uses heat pipe to transfer heat energy, there is no water in the vacuum tubes, and it can be used in all climates.
7. Automatic water supply, could supply water self-acting without any other installation and could able to be pressured.
Feature:
Special Anodized aluminum alloy frame to ensure handsome appearance and can accept high pressure without leakage.
50mm fiberglass insulation and EPDM seal strip to assure the solar collector can work under cold temperature.
Operation Temperature -33 degree to 120 degree.
Patterned temper glass or low iron temper glass (4mm thickness) is not easy broken with very high transmission and low emission
Black chrome or Magnetic blue sputtering coating has very higher absorption rate to ensure the high efficiency.
1. Uni-directional heat transmission
2. Can start from lower temperature
3. Faster transmission
4. Lower heat capacity
5. Low temperature resistance
6. Freeze-proofing
7. High frequency soldering inner tank
8. Rating pressure is 0.6Mpaú¼0.4Mpa separately, can connect directly with the city water system
9. No water in the vacuum tubes eradicates the incrustation scale, thus keeping them running in high efficiency,
