The JHCevacuated tube solar collector is device that absorbs thermal energy from the sun and converts it into usable heat. The heat is normally absorbed by water, or a freeze resistant water mix, which can then be used to supplement hot water heating, space heating and even space cooling via use of an absorption chiller or dessicant cooler technology.Features:A solar thermal collector is a solar collector designed to collect heat by absorbing sunlight.The simpler collectors are typically used for supplemental space heating in residential and commercial buildings.A collector is a device for converting the energy in solar radiation into a more usable or storable form.The energy in sunlight is in the form of electromagnetic radiation from the infrared (long) to the ultraviolet (short) wavelengths. The solar energy striking the Earth's surface depends on weather conditions, as well as location and orientation of the surface, but overall, it averages about 1,000 watts per square meter under clear skies with the surface directly perpendicular to the sun's rays.Specifications Quality Guarantee:We provide 5years warranty of products and shipment with 1% spare partsWe can send the parts free on condition that there is any breakdown with convincing evidence1% spare parts include:- Wiper scraper seal- Tube holder- Screws & screw capsQC Team:A QC team with more than 10years’ experience and technical personnel.
