With our own in-house metal fabrication facility, Excalibur can provide our clients with an extended array of metalwork and engineering solutions throughout the construction process. For example, the liquid-cooled MRI chiller with city water by-pass designed by Excalibur guarantees uninterrupted cooling to the MRI cold head and/or gradient cabinet. If power to the chiller is lost or if a general alarm is triggered, the city water by-pass can be activated to provide cooling to the MRI equipment. We also posses the ability to design and fabricate one-off cryogen ventilation systems which are engineered according to the unique specifications of each job.
