Details of Technologies Developed and Commercialization

Several patented technologies have been developed, demonstrated and transferred for commercialization. A select few technologies are being described here to keep the section brief.

Matrix Exhaust Heat Recovery Units, based on the Indian Patent # 196527 “A Matrix Heat Exchanger Technology” have been licensed to Unidyne and they have installed over 50 MHR Us in capacity range of 135 kW to 6 MW single engine and in some clients sites there are multiple of 6 MW Engine Exhaust HR Us deployed. These Typical pay backs have been in the range of 6 to 12 months if the operations are over 12 h/d.

Super Heat Recovery Water Heaters, SHR_WH, based on the Vented-Double-Wall Tube-Tube Heat Exchanger Technology has been upgraded through a consultancy project at HPL_IITB and the size reduced to half the size as compared to the earlier 90 units installed in McDonalds by a company being incubated through SINE at IITB. After successful deployment of the new design, this technology was licensed to Mech World Eco, Nashik, and they have now installed additional 250 SHR_WH in McDonalds alone and several more in more in Infosys, Fortis Hospital and several other food processing units and hospitals. This technology has also been transferred to Promethean Energy Pvt Ltd, Navi Mumbai and Raavit Refrigeration Company, Thane, for installation on R22, R134a, ammonia and other refrigeration systems.

Multi-Utility Heat Pumps, MUHP, based on our Indian Patent, IP, 212 316,on Multi-Utility Vapour Compression Heat Pump. Various types of MUHPs, Air to Water, Air Water to Water, Water to Water and Water to Water have been designed, built and deployed in residential, commercial and industrial applications. After about 10 to 15 installation, in various industries by HPL_IITB through consultancy mode and through its SINE incubate company and then licensed to Mech World Eco, Nashik. MWE has started selling various MUHPs, which they list as Multi-Utility Heat Generators. They have also sold various types of such MUHPs to McDonalds, Infosys and hospitality and hospitals.

Heat Pump for Canteen Application, HPCA, based on our Indian Patent, IP, 212 316,on Multi-Utility Vapour Compression Heat Pump and the Indian Patent, IP, 205362, on Tube-Tube Heat Exchanger, TT_HE. The 6-in-1 Multi-Utility Heat Pump has been designed, built and deployed. Has been in operation in an Industrial Canteen since May 2017 and is simultaneously catering to the following six utilities:

Hot Utilities: Water 2,000 L @ 60oC for Cleaning + RO Water 200 L @ 95oC for Cooking / Heated Fresh Air 10 to 12 TR @ 41oC for Space Heating in Winter

Cold Utilities: Dehumidified Fresh Air to Maintain Indoor @ 27oC & 60% RH in Summer and Monsoon + Potable Water 150 L @ 15 to 18oC for Drinking + 1000 L Refrigerated Cabinet Maintained at 10 to 15oC for Preserving Fresh Fruits, Vegetables, Milk, etc.
