Brand Name: OEM
Model Number: QR-KL
Place of Origin: Zhejiang, China (Mainland)
Key Specifications/Special Features:
Heat pipe series
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 Upipe heats up,and the U pipe conducts thermal energy to the water inside the storage tank ditectly (or through internal copper coil),With a testing pressure of 1.2 MPa, Working pressure is 0.6MPa
advantages
1. the test pressure reach to 1.2 MPa, can be connected directly with city tap water.
2. No water inside the evacuated tubes, the system can still in service even with several tubes breakage.
3. Can be used all year round in the cold climate.
