Solar Water Tanks (200liters)------------------------------------------------------About JINYI SOLAR Factory:1. We have 12 year history/experience in manufacture solar water heater products, include solar collectors, Cylinders;2. We are a directly manufacturer, have our own factory, we manufacture: Pressure stainless steel cylinder, heat pipe/U-type solar collector, split pressure/heat pipe pressure/nonpressure solar water heater.etc;3. We are near Shanghai city for 25minutes by train, it’s convenience for you to visit us, welcome!4. Our factory is 12000 square meter big, our showroom is 100 square meter big;5. We 100% test each cylinder with 10Bar/1.0MPa pressure to avoid leakage problem;6. We produce each order strictly with the Auto CAD drawing paper.7. Our production capacity is 3000 units/month; Advantages of Jinyi Solar Water Heater Boilers:1. Extremely low heat loss: all Jinyistainless steel hotwatercylinders are very well PU foam insulated, compared to traditional mineral wool is about 40 % better, for a normal household this equals a saving of approximately 450 kWh per year. Under one-off modling/high pressure foam technology, with 50-60mm thickness, 42Kg/m3 density, the heat loss is extremely low.2. Anti-corrosive protection: Use super bigger magnesium anode for additional anti-corrosive protection, long service life.3. High heat exchange efficiency: Large heat exchanger surfaces make cylinders ideal for solar water heating system.4. Inspection flange easily used for inspection and cleaning the inside of cylinder for maintenance purposes, guarantee the water quality.5. Available with one or two heat exchangers, suitable for every application.6. Adopt special Incoloy 800 electric heater, which have super anti-corrosion, dry-heat resistant, super heat conduction, etc feature. 7. Inner tank and internal heat-exchanger coils made of same material-stainless steel, can welded together, avoid potential leakage problem.8. Each inner tank is individually tested for high pressure up to 10Bar/1.0MPa pressureData for 200L Solar Water Boilers:
