What F. Harley does

F. Harley & Co. Pvt. Ltd. (trade name F. Harley) is a Kolkata-headquartered, privately held specialist in industrial air pollution control and particulate management, tracing its legal origins to an English industrial textiles company founded in 1825 and acquired by the Shah family in 1967. The company is one of the oldest members of the Bengal Chamber of Commerce. Following its mid-1980s diversification into Air Pollution Control Equipment, F. Harley has built a portfolio around three business areas: fugitive dust emission control (ADS™ Dry Fog Agglomerative Suppression, Chem-jet wet suppression using Compound MST wetting agent, stockpile sprinkler systems), process particulate build-up control (Nirafon Acoustic Cleaning Systems in NACS and NCSD variants for temperatures up to 1000°C and 1500°C respectively), and humidification & outdoor cooling (Harley HumidiKool). It also offers the Kompulse-Kompak line of proprietary filter elements for baghouse filtration.

Its product stack rests on three long-running technical collaborations: The Raring Corporation (USA) for ADS dry fog dual-fluid sonic nozzle technology, Dust Suppression International (UK) for Chem-jet and Compound MST, and Nirafon Oy (Finland) for acoustic cleaning. Manufacturing is in-house at a 30,000 sq.ft. facility in Kolkata with complete test facilities. Quantified performance claims include 90–95% dust control efficiency with passive containment, Compound MST dosing at 1:3750 water ratios, NACS sound pressure exceeding 150 dB at 60–250 Hz, and NCSD pulses of 4–10 per second above 170 dB. The USEPA recognized ADS Dry Fog as Best Demonstrated Technology for sub-bituminous and lignite coal in October 2008.

F. Harley generates revenue through a mix of one-time equipment sales (design, manufacturing, supply, erection, and commissioning), recurring Annual Maintenance Contracts, consultancy and site-survey services, and aftermarket spare parts. Quote-based pricing is applied across an enterprise field-sales motion targeting end users, OEMs, and consultants across coal, limestone, gypsum, iron ore, quarry, lignite, quartz, and chrome ore bulk material handling sites. Named customer references include NTPC Unchahar (thermal power) and Paradip Port Trust (port logistics). The company reports 600+ dust-suppression installations and several hundred acoustic cleaning installations across India, Asia, and the Middle East.
