Manual override valve - In the event of a total control failure, a
manual override valve is provided which can be used to
manually introduce liquid nitrogen into the chamber.
Safety features - The lid activates an interlock switch to switch
off the heater, fan and liquid-nitrogen solenoid valves when it
is opened. Safety from overheating due to sensor failure is
provided by a thermal cutout. Relief valves set to 50psi
(3.4bar) are fitted on the input side of the solenoid valves.
Liquid-Nitrogen Delivery System
It is normal to use a 22psi Dura-Lo or Dura-Tech cylinder to
provide the supply of liquid nitrogen to the freezer. The cylinder
is filled by the supplier and, being self-pressurising, does not
require a pump to deliver the liquid nitrogen to the freezer.
Note The freezer must not be used with supply pressures in
excess of 30psi.
Personal Computer (PC)
The optional DeltaT software on a PC enables you to create and
store profiles. You can run one of these profiles from the PC and
view the recorded chamber and sample temperatures graphically.
All results from the run are stored on the PC for traceability
purposes.
Any profile you run from the PC can be stored in the freezer's
memory. This enables you to rerun the program directly from the
freezer, without having the PC connected.
Printer
If you are using a PC, it is strongly recommended that you
connect a printer. You can use the printer for tasks such as
printing programs and graphs.
