Product Name: Heat Pipe Solar Hot Water Heater Certification: CE, ISO9001, SRCC,Keymark Collector Components: Heat Pipe Vacuum Tube Interior Material: Stainless Steel Pressure: Pressurized Structure: Compact Type Tank Material: Color Steel / Stainless Steel Working Pressure: 12 Bar Anti-Freezing: -40 Centigrade Trademark: INLIGHT Transport Package: Export Carton Specification: 10- 42 tubes Origin: China(Mainland) HS Code: 8419191000 Product Description Heat Pipe Solar Hot Water Heater1.energy saving , high efficiency2. intelligent controller , easily to operate3. antifreezing at -36 degree .4. Certifications : CE ISO Solar Keymark TUV ..Features description:1) No water flows into vacuum tubes, system works well with withdrawal of one or several heat pipe vacuum tubes2) Super efficiency of insulation with polyurethane foam; No vent with less heat loss as compared to nonpressurized type3) System withstands pressure more than 6 Bar, can be connected directly with tap water, more safe system and comfortable hot water use.4) System can be equipped with auxiliary electric booster and intelligent controller for solar heating assistance and automatically system controlMainly Component and Functions : 1. Heat Pipe Vacuum Tube: Three-target galss tube, aluminum fin and heat pipe with its inner medium together makes an efficient solar collecting device for heat exchange.2. Inner water tank: Thickened food-grade SUS304-2B stainless steel as storage tank keeps the water clean and drinkable.3. Water tank shell: Stainless steel SUS304 as outer shell, much more durable and appealing with super mechanical performance.4. Insulation Layer: High-density polyurethane integrated foam-forming with twice slaking treatment5. Supporting Bracket: Stainless steel or aluminum alloy plate, super weight bearing and wind resistance design (140 km/hr), ensure more than 12 years lifespan .Optional Devices:Electrical heater, as an auxiliary heating element in case of raining or cloudy days so as to ensure a continous hot water supplyIntelligent controller, automatically controls startup and ceasing of auxiliary heating device with temperature sensor, more intelligent operationAnod magnesium bar: Soften hard water in system so as to protect the storage tank from water scaleSpecifications:Item No.Water TankCapacity (L)Solar Vacuum TubeAbsorberArea (m2)Loading/SetsQty / pcsSize / mm20GP40HQILH-5818A470S-12H10012Φ58*18001.1363154ILH-5818A470S-15H12815Φ58*18001.4153130ILH-5818A470S-18H15318Φ58*18001.6944107ILH-5818A470S-20H17020Φ58*18001.884099ILH-5818A470S-24H20024Φ58*18002.263586ILH-5818A470S-30H25530Φ58*18002.822768ILH-5818A470S-36H30636Φ58*18003.3824581.
