Heat Pipe Vacuum Tube

Features:

Much more anti-frozen protection, especially suitable for areas temperature between 0°Cand -45°C in winter.

Bearing high pressure, resistance to air drying, non-explosive

Heat starts fast, easily make water hot, even boiling.

Many specifications choices, make 70-130Kg/sq water heated to 55°C

High absorption rate: αs≥902, low emission rate: εh≤8%, daily average thermal efficiency: ηd≥50

Advantage:

High thermal efficiency, annual use:  Advanced heat transfer methods, excellent solar selective absorbing coating and high vacuum collector system state so that the daily average thermal efficiency of 50% or more. Adoption of new technologies, bearing strong. TJ casing and sink are integrated by welding, product test pressure up to 11kg/CM2, efficiency to solve the scaling down of similar products and flow of small, unstable defects. Overcome the issues of vacuum tube broken, seal and sealing between metal heat pipe glass and metal.

Easy Installation and maintenance: the cell structure of the collector is easy to transport and install. When the root system of a vacuum tube needs to be repaired, may change under the condition of no prejudice to the system operation

Antifreeze, anti-hail shock: a high-performance heat transfer systems in a way that under the conditions of -30 degree temperatures still running, and has less resistance to 25mm in diameter hail shocks.

    4.   Performance: sunshine intensity 850W/CM2, each square can produce 1750-1800 calories, its thermal efficiency>50%
