JIANGSU SUNRAIN SOLAR ENERGY CO. LTD - China

Features Evacuated tubes convert solar energy into thermal energy that is transferred to heat pipes by an aluminum fin with high solar energy absorption and low heat radiance loss. The heat pipe adopts such kind of character that could transmit quantity of heat under low temperature. Character65306 112289With a testing pressure of 1.0 MPa, this system has a working pressure of 0.6 MPa. 212289Solar water heaters can still work even with several tubes broken. 312289Highly efficient insulation with integrated polyurethane foam.
