Household Solar Water Heater Evacuated Tube Collector 25-50 T /
Economy and energy saving, consumption of yearly average of
electricity is as same as 65% of the solar water heater and 25% of
the electrical water heater.The products are adopted the theory of
thermal transmssion:Compressor operates to discharge the high
temperature carrier of the refrigerant and that makes water
heat.That is no exhaust gas discharging and waste residue.
The products are adopted the heat exchanger/condenser of the high
efficient sealed shell type.The water of the system and the
refrigerant operate heat exchanging in the whole dynamic
Vacuum tube solar collector is a new type of solar collector with
higher efficiency, simpler installation and lower cost than
traditional flat plate solar collector. It is widely used in solar
central hot water engineering system.
The collector consists of three parts: ground mounting
bracket/all-glass vacuum collector tube/heat preservation tank.
The design of the vacuum tube solar collector is very flexible. It
can be used to make the appropriate support and installation method
according to the installation size of different building roofs.
1. Super anti-corrosive outer tank: Outer tank is made by 201#
/SUS304 2B stainless steel.
2. Strong inner tank with SUS3042B stainless steel up to 0.41mm.
3. High efficiency vacuum absorber tubes.
4, Stainless steel mounting floor stand.
* 25-30tubes (vertical) / 50 tubes (horizontal) /
* Group manifolds sets (50 tubes X1/2/3/4/5...)
* Installation area need for each group: About 16M2
* Feeding water volume per set: 500-900L
