solar collector

solar collector Parts of production pictures More..... vacuum tube 1, Diameter of vacuum tube: 47mm/58mm/70mm 2, length of vacuum tube: 1500mm/1800mm/2100mm3, quantity of vacuum tube: 15/18/20/24/30/36/42/504, type of the vacuum tube: single target coating tube/velocity of light violet gold tube/glass heat pipe/triple target coating and triple-cavity vacuum tube.heat pipe solar collector parameter:1 Heat pipe includes three target vacuum tube, copper pipe, aluminium fin and silicon seal2 absorptivity: 0.933 reflectivity:≤0.034 glass tube material:high borosilicate, clad layer:copper and Stainless steel5 stuffy solarization temperature:290°C6 freeze proof temperature:-40°C7wind resistance:30m/s8 hail resistance:25mm9 useful time:≥15yearsWorking station:pressure solar water heater Working principle: 1)Solar collector can connect to the pressured water tank and it can be installed on the flat with stand or mounting on the sloping roof without support stand 2)Heat pipe vacuum tube absorbs the heat energy from sunlight, because there is closed-loop between water tank and solar collector, so the heat can transfer to water tank from the solar collector 3)Conductor medium is glycol and water mixture, can endure the very low temperature and anti-freeze, meanwhile it can exchange heat energy with cold water in the water tank 4)With help of the controller system, can balance the temperature of the water tank and the solar collector 5)Temperature difference is higher than preset value, controller system will start the circulation pump and the heat energy can be transferred between the water tank and solar collectorsolar collectorAdvantages: 1)Double coil system can combine with the original water heater perfectly 2)Split pressurized system is special designed for the cold area, more effective than the other type solar water heater if in the cold winter 3)Double coil system can used for heating room 4)Solar collector can be placed on the flat roof or sloping roof or fixed on the balcony, generous and nobler 5)Tank can be put in the house that can reduce the resistance of the roof 6)Whole system can be used for swimming pool heating system7) CE, ISO9001, CCC, EN12975 certified 8) Competitive price on same quality level 9) Prompt deliveryLoading quantity:Item No.Collector ModelTube CoatingAbsorber AreaJNSC-10/58*1800φ58*1800*10AL-SS/Cu1.3m2JNSC-15/58*1800φ58*1800*15AL-SS/Cu1.95m2JNSC-20/58*1800φ58*1800*20AL-SS/Cu2.60m2JNSC-25/58*1800φ58*1800*15AL-SS/Cu3.25m2JNSC-30/58*1800φ58*1800*30AL-SS/Cu3.9m2
