The newly developed refrigeration system and freezer structure offers a quiet environment.
Uniform Cryogenic Temperatures
Mechanically refrigerated design pro-
motes better top-to-bottom uniformity
than liquid nitrogen vapor-phase storage.
V.I.P . PLUS Design
™
Patented revolutionary vacuum insulation
cabinet construction reduces wall thick-
ness and achieves more storage capacity
than a conventionally insulated freezer
without increasing the footprint.
SANYO-Designed Refrigeration
Designed by SANYO specifically
for rugged cryogenic temperature
applications in a laboratory environ-
ment; CFC-free refrigerants only.
Microprocessor Temperature
Control with Digital Design
Precise setting and temperature control.
The temperature inside the freezer can
be set and monitored easily by means
of precise microprocessor temperature
control with an LCD graphic display.
Adjustable high/low temperature alarm;
power failure alarm; filter check alarm;
door ajar alarm; part replacement
time notification.
LCD Control Panel
LCD microprocessor controller features a
full-alarm package with a status alert moni-
toring system. The monitoring system re-
cords internal temperature up to one month
and history of door openings and closings.

Comparison of temperature distribution in a liquid nitrogen freezer (vapor phase) and SANYO's MDF-C2156VANC
mechanically refrigerated cryogenic freezer. Graph shows temperatures at different locations within the chamber.
This data demonstrates that 100% of the MDF-C2156VANC storage space maintains uniform storage temperatures
safely below -130ºC, while temperature in LN
Ideal Alternative to LN
Mechanical Preservation
Freezer preservation provides users
with numerous advantages; uniform
cryogenic storage temperatures, no
worries about sample contamination,
no liquid supply problems, no danger
of sudden liquid eruptions and low
operational costs.
