Freeze cycle: 240 s - TTI <75 s or 2x240 s - >75 s
Freeze cycle: TTI+120 s
In the first group freeze duration is 240s if TTI (time-to-isolation) is < 75 s. In case of TTI>75s a 240s bonus freeze is applied. If no TTI could be documented, a single 240 s freeze cycle is applied in this group in case of balloon temperature -40°C (degrees Celsius) after 60 s.
In the second group freeze duration is TTI (time-to-isolation) +120 s. If no TTI could be documented, a single 180 s freeze cycle is applied in this group in case of balloon temperature -40 °C after 60 s.
