We are a leading Manufacturer & Exporter of Solar Water Heater such as Commercial Solar Water Heater, Industrial Solar Water Heater, Large Scale Solar Water Heater and Domestic Solar Water Heater from India.
Sunline Domestic unit supplies hot water at 60° C and operates on the Thermosyphon / Natural Convection principle. Solar rays strike the selectively coated absorber, which in turn heats the water of the riser tubes by thermal conductivity. The driving force for circulation in such a system is derived purely from the density difference between hot and cold water through the solar collector. As the water gets heated up it becomes lighter, and “automatically rises, and in turn is displaced by the Comparatively heavier cold water from the storage tank. The system is designed to facilitate optimal stratification inside the SS-304/ copper storage tank ensuring the efficiency of the system. The hot water is collected and stored in a properly insulated SS-304 / copper storage tank which ensures that the water heated the previous day also remains hot for an early morning bath the next day.
Hot water availability depends on the absorber plate receiving enough solar insolation (direct sunlight) as well as the capacity of the system installed, depending on the number of persons in the family. The system is made with high quality materials and a design that ensures efficiency, durability, long life and consistent performance. Therefore, there are negligible repair and maintenance costs. The collector is made with good grade aluminium sheet and aluminium extruded section that makes it look better, is lighter in weight, resists corrosion and lasts longer. The riser-header tubes made from copper and absorber plate made from copper with selective coating increases efficiency of the system, ensures better temperature and protects it from corrosive effect. The storage tank is also made from SS-304 / copper and there is a special provision for electrical back-up. Superior quality insulation is used throughout the system for maximum efficiency. The absorber plate is also fitted with a toughened glass sheet with a high transmittency for optimum absorption of the sun’s heat, even during the winter months.
Sunline pressurized solar water heater available for pressure boosting pump operation.
Ideal for use in Dairies, Guest Houses, Lodges, Canteens, Hotels, Hostels, Hospital, Health Clubs, Gymnasiums, Chemical Industries, Tanneries, Sugar Factories, Breweries, Oil Mills, Paper Mills, Preheating of water for boilers &whenever you need hot water.
The Industrial! Commercial Heaters are designed to supply water at 80° C. The absorber plate collectors are technically the same as in the Domestic Heaters but they are larger in number and instead of operating on the thermosyphon mode, the forced flow circulation system with thermostatically controlled fixed or differential temperature controllers is installed. The system consists of an array of collectors, arranged in a series parallel combination so as to optimise the pressure drop as well as the heat collection, while utilising the available space to the maximum. A motor pump is used to circulate water through the collectors. This pump is activated by a capillary type thermostat with the rise in the temperature from the preset condition. The heated water is supplied to a properly insulated storage tank which can keep it hot overnight.
The Sunline Industrial / Commercial System has a payback period of 1-2 years when compared to electric heaters and, 3-4 years when compared to oilfired boilers. With the prices of conventional fuels not likely to decrease in the future, the Sunline Solar Water Heater offers even better benefits.
