We convey our sincere thanks and our appreciation to M/ s Electrotherm family for the development, realization, testing, qualification and commissioning of 10 MW power supply system for our Plasma Wind Tunnel facility. We are extremely glad that M/ s Electrotherm has taken up this challenging task, when no such system was existing in the country. We wish, we should have many more such collaborative ventures in future with M/ s Electrotherm and contribute to ISRO's futuristic advanced R&D programmes.
Mr. P.A. Krishnamoorthy, VSSC-ISRO
Hereby we feel glad to have 4000 KW/ 10 Ton DTi Furnace set along with HSMC lX Caster. We have commissioned this equipments in our plant on 21st May 2018 & found performance which was committed by Electrotherm was achieved. Electrotherm's project execution was extraordinary & their process understanding & support was remarkable. Looking to the performance of other equipments of other makes running within our group, we have found performance of Electrotherm make DTi Furnace to be best.
