Liquid Nitrogen Delivery System
Never connect to a supply pressure in excess of 2 bar (30 psi)
For optimum performance the Kryo550-16 should be configured for the
supply pressure to be used. Two ranges are supported: 0.34 to 0.53 bar (5
to 7.7 psi) and 1.38 to 1.65 bar (20 - 24 psi). Please contact your
distributor if your system needs to be reconfigured. Pressures outside of
these ranges may compromise the performance of the system.
It is normal to use a 1.5 bar (22 psi) EuroCyl or CryoCyl cylinder to provide the supply of
liquid nitrogen to the oven. The cylinder is filled by the supplier and, being self-pressurising,
does not require a pump to deliver the liquid nitrogen to the chamber.
The system can be configured for left or right entry of the hose. Please contact your service
engineer if you want the hose configuration changed.
Kryo550-16 Profile Memory
The Kryo550-16 has two memory locations that are used for storing profiles. These are the
Permanent Profile and Run Profile areas. When the Run button on the control panel is used
to start a profile, the freezing profile stored in the Permanent Profile memory is copied into
the Run Profile location and then started. If a profile is started from DeltaT , the profile from
the PC is sent directly to the Run Profile area and started. The Permanent Profile is left
untouched. This means that after running a profile from DeltaT , the original profile in the
Permanent Profile memory will still be available for use by pressing the Run button.
DeltaT can be directed to overwrite the Permanent Profile memory by selecting the Make
Permanent
option from the PC when running the profile. Refer to the
DeltaT
help files for
further information.
