Jacobsen's MAXIcool™ W (water) or O (oil) is a system of parts for keeping the x-ray tube at a safe operating temperature.  

Using a specially designed, heavy duty cooling pump and multiple sensors, MAXIcool™ ensures that cooling water/oil temperature never exceeds the tube manufacturer's specification. MAXIcool™ is hard wired to the x-ray generator and disables x-rays if there is a cooling fault. 

The system includes cooling pumps, temperature and flow monitors, piping, quick disconnects and other accessories.
