SOLAR WATER HEATER
EVACUATED TUBE COLLECTOR
Evacuated of tubes are absorber of the solar water heater. There absorb solar energy converting it into heat for use in water heating. Evacuated tubes have already been used for years in Germany, Canada, China, and UK. There are several types of evacuated tubes in use in the solar industry. At Orbit, We use the "twin-Glass Tube "technology. This type of tube is chosen for its reliability and better performance.

FLATE PLATE COLLECTOR
Solar hot water system is based on the principle of black body absorption. The black surface of the collector absorbs the heat energy from the sun rays and transfer it to the water passing through the copper tubes. Hot water being lighter in density, raised to the insulated storage tank and equal amount of cold water replace this hot water from the copper tubes.

Solar Water heaters For Boilers
Solar hot water System is based on the principle of black body absorption. The black surface of collector absorbs the heat energy from the sun rays and transfer it the water passing through the copper tubes. Hot water being lighter in density, raised to the insulated storage tank and equal amount of cold water replaces this hot water from the copper tubes.
From solar water heater, we can increase the temperature to the maximum of 95 deg. Industries like Textile, Hotel, Rubber and Dairy industries as already in use of boiler for generating steam. The hot Water can be used as a pre heated water for boiler. Conventional fuels like LPG, Diesel, Firewood, etc., can be saved at 30% to 40% on their daily consumption.
