The energy needs of indian industry are primarily supplied by coal and oil of which is related to electricity, but two thirds are related to heat. a large part of this heat is required in the form of hot air.the industries currently use natural gas, coal or biomass as a fuel to heat air. a typical small industry consumes about 20 to 30 mmbtu per day for hot air. however the resulting emissions and increasing cost of fossil fuels are a grave concern. to address the problem of supplying industry with greener sources of hot air we have developed a product called straut aero, a solar hot air generator which is a fully developed, tested and ready to deploy. aero has a specially designed heat collection element which makes it very efficient with air as a fluid. the successful working prototype is already operational. the maximum temperature of 300 c can be achieved by this solution, which covers all major process air heat application of industries.
