Solar Water Heating System

Solar thermal is the most efficient, affordable and feasible applications of solar energy. Solar thermal heating and cooling systems have a wide range of applications. Heating domestic water for Hotels, Pools, commercial residential and industry is an affordable feasible solution.

Producing electricity from the solar thermal is still attractive in many applications. Beside that, using solar for cooling is under research and development, this technology will be widely used in the hot climate countries.

Simply, Benu is helping you to harvest the daily heat energy of the sun.

Benu is concerned in developing solar solution for aggressive and tough climate.

The thermo syphon system from Benu is designed and fabricated to suite the residential and commercial applications.

The inside serpentine is made from   stainless steel 316 fixable hoses. This material is well known for its high corrosion resistance. This design is the best for the location where we knew that the salt in water is high.
