Parameter list (factory setting)
The following table shows parameter factory settings for
both Blast chillers units (GBC) and Shock Freezers (GBF).
NOTE: Select freezing cycle to run a normal
chilling cycle (Cabinet at 32°F [0°C],
needle probe end cycle temperature at
37.4°F [3°C]).
GBF-3GN2/3 and all GBF Trolley Units (Cycle O Defrost)
