The vortex tube system:
Georges Ranque was the French physicist who invented the Vortex Tube in the 1930.s. The vortex tube technology falls in the category of forced air systems in which pre‐chilled air is pumped inside the suit. They behave in a very predictable and controllable way. The main advantage of this system is instant cooling no need for a refrigerant.

The project ‘Design of Thermal Suits’ for industrial, workers working in hot, stressed conditions was sponsored by Essen Engineers, Mumbai. They initially provided with details of technological logistics along with a vortex tube and a suit. The objective essentially was to use the vortex tube technology and use its specific advantages to create a product which is economically viable and more user friendly then existing technologies i.e. to integrate the technology into a user friendly product designed specifically for the target users.

Final product - Thermal Suit:
The final product is a thermal suit designed for industrial workers working in extremely hot, stressed conditions. The design also respects the highly stressed physical activities of the workers and promises minimum physical stress while using it protecting the worker all the time. The materials selected for the design, down to the zipper are all heat resistant. The suit will also give protection to the worker form occasional splinters and sparks coming out of the furnaces .The worker is also protected from chemical splashes by the suit fabric.
