Prag Group of Industries

What Prag Group of Industries does

Prag Group of Industries is a privately held, family-controlled specialty engineering products manufacturer founded in 1983 in Lucknow, India, by Mr. Rakesh Jain. The company designs, manufactures, and supplies hardware components and sub-systems primarily to Indian Railways, with additional exposure to oilfield and industrial markets. Its 13-product portfolio spans rubber and rubber-to-metal bonded components, polyurethane products (including the patented PU-CCSB), polymer spring packs, locomotive draft gears, bogie-mounted air brake systems (under Knorr Bremse license), filters and filtration systems, plate-type heat exchangers, compressed air treatment equipment (Aquacheck air dryers), HVAC systems for passenger coaches and driver cabs (Koldform brand), a VR-based driver training simulator (ECOSAFE VR), onboard water purifiers (Arcticove), and auxiliary power units (APU) for fuel-saving automatic engine shutdown.

The company's revenue model is anchored in direct B2B procurement contracts with Indian Railways and its constituent bodies (Railway Board, RDSO, Production Units such as ICF Chennai, Zonal Railways, and Wagon Builders), supplemented by licensed manufacturing royalties from international technology partners and recurring aftermarket revenue from replacement filters and consumables. Prag combines indigenous R&D with technology licensing from global partners including Chemtura, Knorr Bremse, Clark Filter, Oil States Industries, Pars Komponenty, REDS SA, and Molinari Rail. Operations span two manufacturing locations (Lucknow and Dehradun) with 250,000+ sq ft of covered area and a workforce exceeding 500. The business is entirely bootstrapped with no disclosed external institutional funding, and the leadership transition to second-generation management (CEO Gokul Jain, COO Sarthak Jain) suggests succession planning is underway.
