  • Glass Vacuum Tube Solar CollectorOur solar collector uses a double-walled borosilicate glass vacuum tube to absorb heat. It offers high heat efficiency and is economically priced. This evacuated tube collector is suitable for use in regions with good sunshine conditions and winter temperatures above -20℃.
  • Highly-absorptive Vacuum Tube Solar CollectorThe highly-absorptive vacuum tube solar collector, as its name suggests, uses highly-absorptive vacuum tube for solar energy collection. It provides high thermal efficiency and reasonable price. The solar thermal collector operates normally even at the temperature of -20℃ in winter.
  • Heat Pipe Solar CollectorThe heat pipe is made of red copper and it transfers heat via a liquid medium.
    No water flowing inside the vacuum tube makes the collector more resistant to low temperatures.
    Our solar energy collection device has a strong aluminum alloy manifold with ventilation design for better wind resistance.
  • Heat Pipe Evacuated Tube Solar Collector As a key component of a solar water heater, the heat pipe evacuated tube solar collector is used to capture solar energy and convert it into thermal energy which is then used to heat domestic water.This solar thermal collector consists of a glass evacuated tube and a red copper heat pipe which is placed inside the evacuated tube.
  • Metal Heat Pipe Solar Collector The metal heat pipe solar collector is used to collect solar energy for the heating of water or buildings. It consists of vacuum tube, red copper heat pipe, metal heat absorption wing, and manifold.
  • U-Pipe Solar CollectorThe U-pipe solar collector is characterized by good water circulation, high heat transfer efficiency, as well as no risk of tube breaking and leaking. It mainly consists of U-shaped water pipe, highly-absorptive vacuum tube, insulation layer, and frame.
  • Flat Plate Solar Collector Suitable for residential or commercial solar water heating projects, the flat plate solar collector, a key component of the flat plate solar water heater, consists of absorber plate, glass cover, insulation layer, and shell.
  • Lithium Bromide RadiatorAs an ideal replacement for traditional radiators, the lithium bromide radiator is commonly used to heat buildings. It can operate by using a variety of heat sources, such as electricity, marsh gas, natural gas, solar energy, and so on.
  • Heat Pump Water HeaterUnlike traditional solar products that are unable to work at night or in cloudy, rainy, and snowy days, our heat pump water heater can work normally at low temperatures (> -15℃).
    The air to water heat pump is convenient to install and easy to use.
  • Monocrystalline Solar Panel A solar cell, also called photovoltaic cell or photoelectric cell, is a solid state electrical device that directly converts solar energy into electricity by using the photovoltaic effect. The conversion efficiency of crystalline silicon solar cells can reach 29% in theory.
  • OFF-grid Solar SystemThe KD-PV-1KW off-grid solar system uses the solar panel to convert solar energy into electric energy which is used to charge batteries and power loads. The addition of an inverter allows the off-gird solar power system to convert direct current coming from the batteries into alternating current which can be directly applied to household appliances.
  • Wind Turbine GeneratorWind energy is a kind of economical, renewable energy. A wind turbine generator produces electricity by harnessing the power of wind. This brings many benefits, such as cut electricity bills and reduced carbon footprint.

As an experienced solar products manufacturer in China, Kaisundun offers a wide range of products, including solar water heater, solar collector, heat pump water heater, solar panel, wind turbine generator, and more. Our solar water heaters are used in industrial, commercial, and residential applications to provide hot water (below 60℃) for heating, bathing, swimming, etc.

Our solar water heaters and solar collectors are reliable, economical, and durable. They have been exported to many countries and regions, such as Germany, Netherlands, Sweden, Spain, Romania, Poland, Ukraine, Russia, Mexico, Chile, Columbia, Kazakhstan, India, Philippine, Saipan, and French Polynesia, to name a few.
