Concentrating Solar Power – Parabolic Trough


Parabolic Trough System

We thrive to offer innovative solutions and make sure that the use of alternate energy sources is not limited to applications like water heating for domestic usages but also addresses the burdensome requirements of industries. Some of the solutions that we have offered to the industries with flair are solar energy based steam generation, oil heating and solar AC.

Decoding the Parabolic Trough System

Trough systems use large, U-shaped (parabolic) reflectors (focusing mirrors) that have oil-filled pipes running along their center, or focal point. The mirrored reflectors are tilted toward the sun, and focus sunlight on the pipes to heat the oil inside to as much as 750°F. The hot oil is then used to boil water, which makes steam to run conventional steam turbines and generators.

In solar parabolic trough power fields‚ a heat transfer fluid (HTF) is circulated through the receiver tube and returned to heat exchangers in the power block, where the fluid is used to generate high-pressure steam. Hot oil pumps are used to move the heat transfer fluid through the collector tube, meeting temperature application requirements of up to 750°F/400°C.

In order to optimize the cost of generating electricity from the sun, different technologies are best suited for each project depending on the location, size, and energy use profile.

Zodiac Energy has the knowledge needed to develop, build and operate solar power plants and industrial installations, using concentrating solar power (CSP) technologies.

The company is focused on the execution of EPCM Projects in all their phases: Engineering, Procurement, Construction, Commissioning and Operation & Maintenance.


Air Conditioning

Air Conditioning

The solar air conditioning system uses parabolic trough to provide solar thermal heat by concentrating the sun’s energy on a receiver tube and heating the recirculated heat transfer fluid within the system. The generated heat is then used to drive the absorption chiller to provide a renewable source of industrial cooling.


Water desalination

Water desalination

Solar Water Energy, has patented a new and exciting technology that converts saline water, sea water, and most contaminated water into pure water utilizing solar energy. The Solar Distillation System combines water desalination technology and solar power to make fresh water and render it as potable water for irrigation or industrial use. In addition, the solar thermal energy stored in each plant is circulated and reused again and again. The surplus heat in the system produces electrical power through a Solar Thermal Energy Conversion System. The excess thermal energy also can improve the efficiency of existing power generating plants. Construction, operation and maintenance costs of plants are very competitive when compared to reverse osmosis.


Solar Steam and Process heat generation

Solar Steam and Process heat generation

Steam is water vapor, the gaseous phase of water, which is formed when water boils. In common language it is often used to refer to the visible mist of water droplets formed as this water vapor condenses in the presence of cooler air. Parabolic trough technology delivers safe, affordable, and reliable high-temperature process heat for industrial, agricultural or manufacturing processes requiring large volumes of hot water or steam in the range of 200–500 °F/ 93-260 °C.


Power Generation

Power Generation

Trough system uses trackers to follow the sun and reflectors and optics to concentrate and intensify the thermal energy from the sun into a heat transfer fluid. The transfer fluid is then passed through a turbine to create power. When combined with thermal storage capacity, the system can buffer clouds and produce power at night – offering reliable electricity that can be dispatched when needed to meet base-load demands.
