1. High pressure storage tank(Testing pressure=9 bar), using SUS304-2B, 1.2mm-2.0mm.
2. Less heat loss as compared to the non pressure model, Heat Preservation: 72-90hours
3. Highly efficient heat pipe technology, Anti-freezing in cold winter, whole system can work well in -35
4. No water introduced into vacuum tube, no water out if tube broken
5. Max. Pressure bearing: 1.2MPa
6. Can be used all year round in the cold climate. Hail resistance: 25mm / 35mm
