hot water geysers
| Sangle high-efficient vacuum heat collector tube |
| 1) Excellent material: High borosilicate glass 3.3 is adopted as the raw material. Its performance accords with requirements of ISO3585:1991. |
| 2) High thermal efficiency: Pure vacuum layer without impurity. Degree of vacuum is high and lasts long, possessing extremely high absorption to sunlight with extremely low thermal emissivity. |
| 3) Small thermal losses: Higher degree of vacuum is kept between vacuum heat collection pipes, reducing thermal losses caused by heat conduction and heat convection to the maximum. |
| 4) Long life: Performance of film plated layer is stable, being not easy to ageing and attenuation. Processes in links of material selecting, production, transportation and quality inspection, etc. are strict with longer service life. |
| 5).Corrosion resistant: Performance against chemical corrosion is extremely good, appropriate to various kinds of water quality. |
| 6).High degree cold resistant: Even in high latitude in Northeastern China area with high degree cold temperature bitter cold, hot water can still be used normally, displaying super high heat collection rate. |
| 7). Great strength: It shall not be broken under impact by Ø 25mm hail. |
