7 Operating the LN2 Cooling Equipment

This chapter gives specific information for the oper-
ation of the liquid nitrogen cooling equipment of
TTK 600.

7.1 LN2 Consumption and Operating
Time

The typical consumption of LN2 does not exceed
4 L/h. This corresponds to a measuring time of max.
25 hours in case that a Dewar vessel with a volume
of 100 L is used.

7.2 Typical Cooling Curves

For typical sample holder cooling curves with maxi-
mum cooling rate for the liquid nitrogen cooling
equipment and the compressed-air cooling equip-
ment refer to chapter 8.8.2.1.
