We are Haining Deno Solar Equipment Co., Ltd based in Jiaxing , China. We are member of Tradekey.com since July, 2010. Our business is related to Energy Products industry and we specifically deal in solar water heater. Please find our product details below: Pressurized solar water heater Compact Pressurized Solar Water Heater 1, The compact pressurized solar water heater system can endure the max pressure up to 0.6Mpa.As the system is pressurized, so it can keep a constant temperature of water in the tank 2, There is no water in the vacuum tube.so even if the vacuum broken, the system still works normally without water ***** copper pipe inside the vacuum tube could quickly transfer the heat into the water tank through the liquid medium inside the cooper pipe. 3, It can endure the freezing -35 degree centigrade and 25mm hailstone. 4, For inner tank, we adopt high frequent melting ***** can directly connect with tap water ***** can solve the low heat efficiency problem caused by fur. Specification: ***** tank:SUS 304-2B food grade stainless steel 1.2mm-1.5mm 2, outer tank:SUS 304-BA stainless steel 0.31mm-0.41mm 3, Bracket:Galvanized steel with powder painting 1.2mm-1.5mm 4, Heating insulation layer:55-60mm imported PU 5, vacuum tube: high borosilicate3.3;coating:ALN/ALN-SSCU Pre-heated solar water heater Pre-heated Solar Water Heater Advantages: A cooper coil is installed inside the tank as the heat exchanger. When water flows into the cooper coil, it absorbs heat from the water in the tank, therefore, the water tank is just a heat storage Features: 1, Can be used at any time to warm the cold ***** can overcome the shortcoming of traditional solar water heater, such as slow heating rate, long waiting time. 2, High efficiency:A special heat exchanging mode is adopted to avoid mixed effect , so cold water can be heated at any moment 3, Water pressure is same as tap water ï¼›it can be connected directly to city tap water system 4, Green and economical .No pollution in working, no cost for hot water 5, Easy operation: automatic water supply , you can take it easy and enjoy good time. 6, Fashionable:the appearance is nice and attractive and can fit into the surroundings properly. Material: 1, Inner tank :quality steel sheet of 2.0mm with PE-X coating 2, Outer tank :0.4mm thick galvanized steel sheet 3, Bracket:1.6mm thick color steel with electrostatic plastic coating solar water heater Non-pressured solar water heater Water Tank: 1, SUS304-2B Inner tank 2, Polyurethane foam insulation 3, Stainless or aluminum support 4, Trivalent element evacuated tube 5, Electromagnetism or ball valve(optional) 6, Electrical boost heater (optional) Working principle: 1, The high quality vacuum tubed absorb the solar autraviolet ray, then heat the cold water in the vacuum tube 2, The hot water rise in the top of the water tank , and the cold water sink to bottom then heat by solar collector.So the whole system is always circilating continuously 3, The electromagnetism or ball valve can perform the water supply automatically, the water in the tank is not sufficient, the electromagnetism valve will open its valve, the tap water flow in the water tank, if the water is full, it will close the valve automatically Feature: The DENO-P01 type has the stainless shell, so it can be used in the acid rain area, the A8-1 has aluminum alloy, the support is very light, Besides, it has 15years long life span, and the vacuum tubes can work individually, so if the only one of them can&＃039;t work , it won&＃039;t influence on the ***** spare parts can be changed freely, it is suitable for the many resident buildings.
