Specification:

How it works? 
In Streamline closed circuit systems which are recommended for frost prone and poor water quality situations, antifreeze fluid is used to circulate through the collectors. The heat collected from the panels is transferred from the fluid to the water in the tank by a heat exchanger. The circulator is regulated by a control unit on the water heater. This ensures the optimum use of the sun's free energy. With a GKINTL streamline solar water heating system you can choose from a range of boosters including in-tank electric or gas boosters to ensure you always have hot water on tap even on cloudy days.

Flat Plat Solar Collector:

VISION flat plate solar thermal collector is suitable for residential or commercial solar water heating projects. The selective coated aluminum absorber sheet absorbs up to 95% of available sunlight converting into usable heat.

1. Glass: Toughened low-iron glass (glazing) protects the absorber from the outside environment while allowing through ≥91% of sunlight.

2. Absorber: A thick sheet of copper or aluminum is coated with a highly selective coating that is extremely efficient at absorbing sunlight and converting it into usable heat. The absorber plate is ultrasonically welded to the copper riser pipes.

3. Insulation: The insulation helps reduce heat loss from the sides and back of the collector. High-density polyurethane and glass wool are chosen by VISION company to greatly reduce weight and heat lost of the collector.

4. Riser & Header Pipe: The header and riser pipes are brazed together to form a harp shaped heat exchanger that the solar system water or fluid circulates through. The absorber sheet is ultrasonically welded to the riser pipes, thus transfers heat to the water or heat transfer fluid.

5. Frame: An aluminum alloy sheet seals the back and frame of the panel and adds to the rigidity of the collector. The rails in the frame are designed for easy mounting attachment.

 Pressure Hot Water Tank:

A pressure storage tank is designed for VISION flat plate solar water heater to supply pressurized domestic hot water.

1. Inner water tank: Food-grade stainless steel or enamel coated tank keeps the water clean and drinkable, automatic argon-arc welding technics ensures no leakage and long lifespan more than 30 years. VISION hot water tanks have all been immersed in water and tested with 12 bar pressure to ensure no water leakage in high pressure condition.

2. Insulation Layer: High-density polyurethane Integrated-foaming with twice slaking treatment, preserves water temperature constantly.

3. Tank shell: White painted color steel with beautiful appearance, super in corrosion resistance, much more durable especially to ocean coast weather condition.
