University of Nizwa Professor Granted Patent for New Thermal Heater
Media and Marketing Department
A professor at the University of Nizwa has been awarded a patent for a new design of a thermal fluid heater.
Dr Dhananjay Yadav, from the Department of Mathematics and Physical Sciences at the College of Arts and Sciences, received Patent No. 212453 (Design No. 464670-001) on 3 November 2025 from the Patent Office of the Government of India.
The device is designed to provide safe, energy-efficient heating through a controlled thermal-fluid system. It combines electro-thermal mechanisms with regulated heat-exchange chambers and a safety-enhanced fluid pathway. According to Dr Yadav, the heater achieves higher thermal efficiency, stable temperature control, and reduced energy consumption compared with conventional boilers or direct heaters.
The design is intended for a wide range of uses. It could support hospitals and healthcare facilities in sterilisation and the heating of medical materials, while laboratories and research centres could benefit from precise temperature control. The food and beverage industry may also use it for processing and preservation. Dr Yadav said the device could also be adapted for household and small-scale industrial applications.
Following the patent, work is underway to develop a functional prototype. Testing will focus on energy efficiency, thermal stability and safety. The project also includes partnerships with industry to explore commercial production and technology transfer opportunities.
Dr Yadav’s research involved international collaboration and multidisciplinary input. Challenges included achieving high efficiency in a compact and cost-effective design while ensuring safety across different applications. Iterative design and material testing helped overcome these obstacles.
The team is now exploring related projects, including hybrid solar-thermal heating systems, low-emission industrial heating technologies, and smart-monitoring modules to automate temperature control. Plans are also underway to adapt the heater for both large industrial and portable domestic use.
