Integrative pressure solar water heater

Advantages Highly efficient absorber of high performance with daily average efficiency ≥ 55% and (≥42% in winter) Start up quickly, heat pipe transfer the heat energy into the storage tank in one direction. Withstand pressure of 6 Bar, can be connected directly with home tap water. No water inside the evac uated tubes and the system operate normally even if some tubes werebroken Highly efficient insulation with polyurethane foam for about 72 80hours; Anti-freezing: ≥ -35 degrees and works normally under the pool conditions Technical data Integrative pressurized solar water heater Inter-tank Food grade and high anti-corrosion SUS 304-2B stainless steel& thickness 1.2mm Outer-tank Color Steel painted with corrosion layer &thickness 0.4mm Insulation 50 mm Polyurethane foam (heat preservation 72hrs) Collectors Φ58×1800 heat pipe vacuum tube Heat pipe in tube Oxygen-free copper (working temperature range -30°C—+300°C) Installation angle 15°-90°(Here 45° best) Coating of tube Al-N/Al high selective coating Working pressure 0.6Mpa Testing pressure 0.9Mpa Bracket Galvanized steel plate/Stainless steel/Aluminum Alloy, &1.5mm Interval of tube 75mm Daily efficiency ≥55% (≥42% in winter)
