About Us

Energy Resources International Co. Ltd. , known as ERI. ERI chose to enter the medical device field since 2013. ERI started to develop Carbon nanotube (CNT) and took advantage of CNT’s distinctive material properties and effectively apply it to X-ray light emission solution.



    ERI's distinctive cold cathode-driven X-ray tube is developed by a proprietary CNT technology. This technology combines with the unique proprieties of high conductivity and structural robustness of CNT, which produces the most efficient field emission source for X-ray.  Under the vacuum environment, the CNT-based cold cathode can stand up to 2,000 degrees Celsius while maintaining the thermal stability.  For various application purposes, the ERI's core CNT-based tube can be divided into reflection type X-ray tube and transmission type X-ray tube.
