Solar VTS Non Pressurised

Non Pressurised
Normally non pressurised systems are working up to 0.8 Kg / Cm2 , The storage tank is placed at a certain height relative to the top of the collector to prevent the reverse circulation during off-sun shine hours. In this system, hot  water storage tank can be under normal pressure of cold water overhead tank so gravitational force of overhead cold water tank comes to bottom of  hot water tank at normal pressure ( non pressurized), hot water comes out from top of hot water solar tank and release at the end of tap as a regular.

Vacuum tubes assimilate the advanced 12 years of spattering deposition of trivalent element technology, high borosilicate glass, gradual change of CU - AL - N / SS selective complex absorptive coating. And these make vacuum tubes have high performance of absorptance and low reflection ratio. Through the interlayer, vacuum has a unique effect of thermo, with its temperature up to 380oC of idle sunning, performing a strong heating ability.
