Jiangsu Sunpower Solar Technology CO., LTD

We are Jiangsu Sunpower Solar Technology CO., LTD based in Changzhou , China. We are member of Tradekey.com since October, 2009. Our business is related to Home Appliances industry and we specifically deal in solar products. Please find our product details below: solar collector with vacuum tube heat pipe 1. Borosilicate glass according to ISO3585:1991; transmittance of borosilicate glass:0.92.Absorbance of solar selective absorptive coating:0.94; Hemispherical emittance:0.08; Getter according to GB/T9505-1998. 2. Start-up temperature: no more than 25℃. 3. Start-up time: no longer than 2 minutes under normal sunshine. 4. Low temperature resistance: no breaks at -30℃. 5. Heat impact resistance: no damage after over 3 time’s alternative impact of cold water below 25℃ and hot water over 90℃. 6. Pressure resistance: can withstand 0.6Mpa. 7. Hail resistance: no damage by the impact of 25mm diameter hail. solar water heater 1) Inner and outside water tank shell all are made of SUS3042B food grade stainless steel plates, welded by argon arc. Water is pure and drinkable 2) Heat insulation of water tanks adopts polyurethane foam and the thickness is 55mm 3) Silicon rings to connect and seal them 4) The tubes and supports are adjustable. The power bearing is average and can assure the vacuum tubes to use for a long time 5) Whole glass vacuum tubes adopt super hard borax and silica glass 6) Absorption rate: =93%, thermal radiation rate: =6% 7) It resists 25mm hail and the using life can last 15 years 8) Temperature when exposed to sun without water: 250oC, 2.5 hours to boiling point if using single tube 9) If you use electrical appliances to aid heating and to switch off the power supple before bathing 10) Please test the water temperature before using, in order to avoid scalding solar collector with vacuum tube heat pipe 1.
