It is one of the most popular Solar Water Heater with high quality & reliability that gives an excellent performance even in adverse weather condition. Manufactured in a State-of-the-art facility using best of the material & machineries, ‘eleCtra’ is a symbol of excellence. The use of high efficiency evacuated tubes ensure maximum absorption of Solar energy & the high quality insulation of the tank ensures negligible drop in hot water temperature in nights or cold climatic condition. It is helping our several valued users to substantially save their electricity bills or any other fuel like gas, diesel etc.
In case of large commercial & industrial projects, where hot water requirement is in substantial quantity, Evacuated Tube Manifolds are used. Set Of 50 Tubes (25 on each side) are connected with a common header manifold in the centre. Cold water enters the manifold & tubes from bottom, gains heat energy from the Sun & flows upward. Based on the system design, numbers of manifold collectors are connected in a combination of series & parallel connection. Flow & circulation of water is regulated through suitably designed pumping system as per the process requirement.
It is a Solar Collector where Copper Fins are connected with Riser Tube (Copper) by ultrasonic welding. Tube & fins are coated with special Solar Selective Coating to increase the heat absorption from solar energy. Series of riser tubes are connected with bottom cold water header & top hot water header. Water gains heat from solar energy & flows upwards.

The ‘eleCtra’ solar Heat Pipe works on the principle of Thermo-Siphon. The Copper Heat Pipe is filled partially with special heat transfer liquid & Aluminium fin or plate is attached to the Heat Pipe to increase the heat absorption area. The entire arrangement is enclosed in Evacuated Glass Tube. The Heat Pipe has two portions – (1) shaft& (2) condenser bulb. Shaft is placed inside the Evacuated Tube Collector & the bulb is connected to a header manifold. Once solar energy is gained by the shaft inside Evacuated Tube, the heat transfer liquid is heated up & partially become vapour inside the heat pipe. The liquid & vapour mixture moves up & releases heat in header manifold (bulb). Thus the water inside the manifold gets heated upto 1200C.
