Dhama Innovations Pvt. Ltd.

Dhama Innovations Pvt. Ltd. is an Indian technology company, that holds a globally patented Cryothermic^TM Nanotechnology called ClimaCon®. The technology incorporates (electronically powered) novel and efficient heat exchangers, that enable a wide range of user-controllable temperatures, (ranging from -10^oC to 100^oC), inside various kinds of apparel, products and systems. ClimaCon® embedded products and systems are designed to meet diverse critical needs like thermal comfort and pain relief. The technology has also been fashioned into various lifestyle gadgets and accessories.

Dhama Innovations was founded in 2008 by Kranthi Kiran Vistakula, principal innovator of ClimaCon® technology and alumnus of Massachusetts Institute of Technology(MIT), USA. The company has won several international awards and accolades like 'Innovator of the Year 2010' by 'Technology Review Magazine' published by Massachusetts Institute of Technology (MIT), for the innovation of ClimaCon®. Dhama Innovations has gained massive coverage in international media like Economist and BBC for its pioneering work in the field of technology and innovation.

CLIMAWARE^TM and DHAMA are the flagship brands of Dhama Innovations. Initially funded by the Govt. of India Tepp(Technopreneur Promotion Grant) , Dhama Innovations Pvt. Ltd. is now financed by venture capitalists.

The Technology

ClimaCon® is a globally patented Cryothermic^TM Nanotechnology incorporating novel and efficient heat exchangers, that actively add/remove heat from the human body in order to provide thermal comfort and facilitate pain relief. Most cooling systems use fans or compressors to dissipate heat. The novelty of ClimaCon® 's heat exchanger design lies in the complete elimination of fans and moving parts. This has been accomplished through advanced construction incorporating combinations involving nano-materials, and this is what makes ClimaCon® enabled products and systems exceedingly lightweight, compact and portable. ClimaCon® technology is a unique adaptation of the Thermoelectric Effect called Peltier Effect(named after the French physicist Jean Charles Peltier). The thermal efficiency of ClimaCon® systems has been optimized through extensive human body thermal mapping research. This technology empowers the users to control the temperature anywhere between -10^oC to 100^oC inside various products and systems at the touch of a button (in ambient temperatures ranging from -50^o to +55^oC). ClimaCon® leads the global technological front on many counts which are listed below:

• The first heat-sink ever designed to eliminate the need of fan.
• 300% lighter than contemporary solutions.
• A wide-range of on-demand user-controllable temperatures.
• Long-sustained heating/cooling performance.
• Products designed to supplement human thermal management.
• Heat dissipation decentralized.
• Heat sink designed to incorporate all modes of heat transfer.
• Radical elimination of bulky supporting units.

Awards and Accolades

• Winner of 'MIT 1K Business Plan Competition', 2005.

The Applications

Military and Industrial personnel and sport enthusiasts often perform in extreme temperatures, both hot and cold. The US Army advises all of its personnel to have limited activity at WBGT greater than 31^oC and no strenuous activity at WBGT greater than 32^oC. Inspite of this guideline, soldiers have to work in temperatures from 30^oC to 50^oC. Similarly, research by Dr.Tord Kjellstrom, Australia National University suggests that there is more than 50% productivity loss for people working in hot conditions. Extreme heat and cold have negative repercussions on human health and productivity and lead to fatigue, disorientation, injuries, illness and in extreme cases, even death. The main application of ClimaCon® technology is to enable thermal comfort and help niche users like soldiers, industrial workers and athletes maintain a conducive thermal environment. This has been achieved through the design of innovative battery powered (Lithium Polymer), lightweight and completely portable Cryothermic^TM apparel and accessories like Jackets, Vests, Scarves, Gloves and Insoles.

Another noteworthy application of ClimaCon® technology is to facilitate instant and convenient application of hot(Thermotherapy) and cold(Cryotherapy) temperatures for pain management, in the form of CLIMAWARE^TMCryothermic^TM Pain-Relieving System. These modalities fall under the branch of medicine called alternative medicine. CLIMAWARE^TMCryothermic^TM Knee Wrap, Elbow Wrap and Back Wrap are the three ergonomic adaptations of CLIMAWARE^TMCryothermic^TM Pain-Relieving System, designed to provide relief from arthritis, tendonitis, tennis elbow, golfer's elbow, sports injuries and lower back pain.
