Glass Tube Low Pressure Solar Collector

Glass Tube Low Pressure Solar Collector Features description: The glass tube solar collector (nonpressurized) consists of glass vacuum tube, nonpressurized manifold and supporting bracket, working principle is thermosyphon the same as integrated non-pressurized system, water is heated directly in glass tubes, taking advantage of the natural circulation due to smaller density in hot water than cold water. Series or/and parallel arrays of solar collector is usually adopted for large-scale hot water heating project. 1. Especially designed for large-scale hot water heating system, supplying hot water for dormitories, hotels, restaurants, schools, hospitals, factories, swimming pools, and some other sites requiring hot water use or house heating. 2. All-glass vacuum tube, most economical and good performance at the same time 3. Processed color steel shell and galvanized bracket make it a long lifespan as vacuum tubes 4. Easy installation and connection and little maintenance needed Warranty: 3 years international responsibility for integrated collector exchange and 15 years for glass vacuum tube compensation due to original quality problems Vacuum tube Spec.(mm)  Φ47×1500    Φ58×1800   Tube (pcs) 40 / 50/ 60  Material  3.3 Borosilicate glass, magnetron spluttering coating Coating  AL/AL-ALN(H)/AL-ALN(L)/ALN or Cu/SS-ALN(H)/SS-ALN(L)/ALN    Manifold Dimension 180*160mm, 1.0 inch inlet & outlet Inner tank  Food-grade stainless steel SUS304-2B 0.4mm Tank shell   201Stainless steel Insulation  High-density polyurethane integrated foam-forming layer    Bracket  Coated galvanized angle steel 30*30*3mm    Accessories  Stainless bolts & nuts, waterproof silicon rubber seal,  dustproof rubber seal, plastic tube holder Working pressure  ≤ 1 bar     Tilt angle  0~ 90° Hail resistance  Φ25mm diameter    /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
