For temperature class T4 – 5°K less than temperature class or 20°K less than the liquid
boiling point whichever is lowest.
For temperature class T5 - maximum of 50°C or 20°K less than the liquid boiling point
whichever is lowest.
TSA1
Temperature of operating liquid depends on temperature of fresh cooler operating liquid
available.
Minimum operating liquid temperature 10°C for water or operating liquid melting point
plus 10°K.
Maximum operating liquid temperature 50°C or operating liquid boiling point less 20°K,
whichever is lowest.
