Abstract: A centrifuge and a method for preventing ignition of combustible temperature-control media in centrifuges after a crash of the centrifuge rotor are presented. It is monitored whether the pressure in the evaporator lies below a specified minimum pressure and/or above a specified maximum pressure. Measures to prevent ignition of the temperature-control medium can be taken in a targeted manner. In the event that the pressure lies below a minimum pressure, it must be assumed that either a leak or a crash is present, wherein a leak leads to a slow release of combustible temperature-control medium and a crash leads to an sudden release of combustible temperature-control medium. If the pressure lies above a maximum pressure, there is a risk that there is a large amount of combustible temperature-control medium in the evaporator which could be ignited in the event of a crash.
