Our Story

Our Story

Engineering ultrasonics to have a positive impact on every aspect of human life

Ralsonics was founded in 1973 by Suhas Ralkar. After spending three years in USA and UK working on cutting edge ultrasonic technology, his passion for being a part of India’s growth journey propelled him to return to India and start Ralsonics.

Ralsonics started off by making India’s first fetal monitoring systems. These systems were provided to hospitals and doctors all over the country.

Within a year, Ralsonics started manufacturing medical ultrasonic cleaners. These were some of the first indigenous ultrasonic cleaners sold in India. Thousands of these were sold all over India.

That started the journey of innovation over decades. Ralsonics started off with one humble product and now manufactures multiple product lines catering to hundreds of applications.

Ralsonics became a prime contractor and integrator for India’s Auto, Aerospace, Nuclear and Steel industry. Multiple modernization programs were initiated by Ralsonics in these sectors to take India’s industry on par with developed nations.

Over the years, Ralsonics started manufacturing hybrid technologies in conjunction with ultrasonics for scale removal, processing, wastewater treatment and sieving.

Currently, Ralsonics is a provider of ultrasonics for sixteen industrial sectors with products ranging from compact ultrasonic cleaners to large fully automated multistage vacuum cleaning systems.

1973 - 1980 : From inception, Ralsonics manufactured and supplied 1100 fetal heart monitors, 1500 ultrasonic cleaning equipment ranging 120 W to 5000 W capacity as well as 300 ultrasonic thickness gauges.

1980 - 2010 : Ralsonics manufactured 5200 ultrasonic cleaning equipment including over 500 automated multi-stage ultrasonic cleaning plants supplied to BARC, NPCIL, HAL, ISRO, RAILWAYS, as well as leading Auto & Engineering organizations. This includes 100% supply to RMP Mysore first phase, 80% requirements of Nuclear Fuel Complex and 90% of the equipment procured by HAL Koraput Engine manufacturing unit over this period. 1988 : Ralsonics developed India’s first indigenous probe sonicator/industrial processor for ultrasonic processing in food, chemical, pharmaceuticals, cements and paint industry.

2001: Development of Ralsonics Tube Resonator. This is the only indigenous effort to date and Ralsonics is one of only four manufacturers globally. Powered by a micro-processor controlled, frequency tracking and MOSFET/IGBT based generator of 1000 watt capacity, Ralsonics’ tube resonator finds extensive use in automated cleaning plants because it is easily replaceable and can be placed anywhere in the plant.

2002: Manufacturing and supply of special equipment for recovery of uranium dust from Hepa filters for Nuclear Fuel Complex.

2003: Development of RUSSEL- Ralsonics Ultrasonic Spray Electrolytic Process for online pre-galvanising cleaning at 300 m/minute for 100% removal of oil, carbon, dust and iron fines followed by drying before Galvalum coating of CR sheet for auto and white goods application.

2004: Developed India’s largest ultrasonic cleaning installation with 92kW ultrasonics using Ralsonics’ tube resonators.

2004 - 2005: Developed ultrasonic cleaning process for steam generators for L&T and NPCIL using ultrasonic tube resonators.

2005 - 2006: Development of internal cleaning of pipes by external ultrasonic transducers for Chemical, Pharmaceutical, Food & Nuclear Industry. Supplied an equipment to NAPP Narora.

2006 - 2007: Four nuclear decontamination centres supplied to NPCIL at Kaiga, TAPP and RAPP

2008 - 2010: Development of RUBIIT – Resonant Ultrasonic Bubble Ionisation Implantation Transmutation a proprietary technology for online cleaning, scale-removal, coating & nano-scale surface structuring of metal wires, rods and rebars. Technology has been approved by Tata Steel for their long steel products.

2011: Design, manufacturing and supply of single chamber multi-process emission free vacuum vapour Degreaser for TCE /other air polluting carbon based solvents worth 2 crore rupees for two large Indian aerospace manufacturers. Ralsonics developed an international standard probe sonicator/ultrasonic processor with complete capabilities matching imported products.

2012 - 2013: Development & production of Ultrasonic Plasma Processing (UPP) technology for industrial processing and industrial/chemical/manure waste management. Additionally metal recovery is accomplished by this technology.

2013: Design & manufacturing of multistage, degreasing, pickling, rinsing, ultrasonic cleaning and drying plant for 1 lakh brass bullet cases/shift using a rotating drum conveyor worth 4 crore rupees. This is typically used for cleaning electrical stamping hardware & mechanical hardware in pre-plating and coating operations. Eleven such units were commissioned at a defense production unit. Ralsonics developed ultrasonic sieving for powder processing in food, chemical and pharmaceutical industries.

2017: Ralsonics expanded into 5 new sectors and tripled product lines while growing into Ralsonics Research Pvt. Ltd.

2018: Ralsonics won Economic Times Power of Ideas 2018 (www.etpowerofideas.com). There were 5000+ teams from all over India competing over a period of 5 months culminating in a 7-day workshop at IIM Ahmedabad. We were honored to be felicitated by Suresh Prabhu, Union Minister for Commerce, Industry and Civil Aviation. Our winning product was an eco-friendly alternative to acid pickling for removal of scale from steel.
