Field-Proven MWS 2-axis Solar Thermal TrackerMWS R&D Center InaugurationMNRE Award For Solar Energy Innovator

1. Incoming Solar Radiation getsconcentrated by high efficiency MWSParaboloid Dish Concentrator onto acavity receiver with minimum losses

2. The concentrated energy is heat-transferred to various working fluids likehot water, Thermic Oils, etc.

3. Piping system routes energy from eachreceiver to end application for integration

4. Entire process is fully automated and dishtracks the Sun in two axis all year long

Case Studies

Old Setup

• Company had a process that required drying of inorganic slurry

• They were earlier drying inorganic slurry in open Solar Ponds

• Slow Drying Process (5-Day Period)

• Inefficient Handling- Manpower

• Environmental Impact

• Alternate- Special Kerosene Oil Consumed For Subsequent Drying In Paddle Dryers

The Solution

Scope of Work

Turnkey design, Engineering, Supply, & Installation of:

• Solar Field• Hot Air Generator• Tunnel Design &

Configuration

• Dehumidified Hot Air Is Generated By MWS Solar Field and injected

into Tunnel

• Hot Air is injected into the solar tunnel at upto 130 degC

• >90% Humid air is vented out of solar shed carrying moisture from the

sludge

• Solar Drying Tunnels are designed for maximum efficiency and

minimum heat loss

• Truly a non-contact process- No MoC/deterioration/corrosion etc. issues

• 100% indigenous availability

• Completely Modular

• Fully automated operations- A master controller operates all vents, a

weather monitoring system, solar field to maximize evaporation rate
