High Performance Aluminium Alloy U Pipe Solar Collector 10 Tubes
For Swimming Pool
Work principle
Evacuated tubes convert solar energy into heat energy, that is
transferred to U pipe by an aluminum fin with high solar energy
absorption and low heat radiance loss, Liquid (antifreezing liquid
or water) in the U pipe heats up, and the U pipe conducts thermal
energy to the water inside the storage tank directly (or through
internal copper coil), With a testing pressure of 1.2 MPa, Working
pressure is 0.6MPa.
