The freezing zone of the Cryo probe is limited so that footswitch, mains electricity, gas supply and scavenging system. the iceball propagates at the tip. When the footswitch is released, Freeze cycles are controlled by the user operating the footswitch. an active de-frost is caused by the equalisation of pressure on When the footswitch is depressed the Cryo probe freezes and either side of the Joule-Thompson nozzle.
8 The gas condenses when the footswitch is released the Cryo probe defrosts. releasing its latent heat causing a rapid de-frost. Routine functions, like purging the Cryo probe are performed automatically when the Cryo probe is connected to the system.
