60tubes ETC Evacuated Tube Solar Collector , Painted Steel Vacuum
Tube Solar Collector
1) inner manifold: Stainless steel SUS304-2B
2) outer manifold: Color steel or Stainless steel
3) Glass tube dimensions: 47mm x 1.5m x 50 PCS; 58mm x 1.8m x 50
4) Heat preservation: 72hrs
5) Hail resistance: 25mm
Working Principle of Solar collector
1. The solar collector connect with non-pressurized solar tank.
2. The water pass through solar manifold then into vacuum tube,
vacuum tube absorb solar energy, heating the water inside of vacuum
3. According to density difference, the cold water through down
into vacuum tube, and hot water flow up into solar manifold, then
storage in heat protection water tank.
4. After circulation by temperature circulation pump, all of the
cold water will be heated to hot water and storaged in heat
protection water tank.
Features of Solar collector
1. The solar collector is more suitable for solar hot water
project, because you can free compose many solar collectors for
connect with different capacity solar tank, for example, the
capacity can do 1000liters, 2000liters, 3000liters, 100000liters,
200000liters and more , normally use in hotel, swimming pool, and
others large project
2. The solar collector is separated with non-pressurized solar
tank, so it need temperature circulation pump for promote
circulation, when the water temperature is difference between
storage tank and solar collector, the pump will strat working, cold
water will into vacuum tube for heating, and hot water will back to
solar tank for storage.
3. The solar collector and solar tank is non-pressurized , so
exhaust vent on solar collector and exhaust pipe on solar tank is
most important for protection the solar hot water system.
Features of Solar Manifold
1. We have three design for your choose: round type, quadrilateral
type and octagonal type
2. Double sides opening for horizontal type solar collector, single
side opening for vertical type solar collector
3. The solar manifold can opening from 10tubes to 70tubes for
φ47mm/1500mm or φ58mm/1800mm vacuum tube
4. We have many material for your choose: stainless steel, color
armor plate, aluminum alloy and galvanized steel.
5. The color armor plate have different color for your choose :
white, red, silver gray.
