Gulmay offers a broad range of water-cooled unipolar 225KV metal ceramic X-ray tubes from leading manufacturers, providing a variety of target angles, focal spots, and power capabilities. For inspection applications that require different imaging parameters, dual and single focus X-ray tubes are available, with small focal spots for high-resolution imaging.

In addition, Gulmay offers X-ray tubes with Beryllium (Be) windows for low inherent filtration.
