Performance Data
SAFETY
• Alarm lamp and buzzer offer secure
warning of power failure or abnormal
temperature increase.
• High and low temperature warning
provides an audible and visual alarm
when the temperature deviates more
than ±5˚C to ±20˚C (adjustable) from the
set point.
• Alarm ring-back function ensures that
buzzer will resume operation, should
alarm conditions continue after it is
silenced.
• Microprocessor-controlled filter-clog
check function protects the refrigeration
circuit.
• The rugged, one-handed outer door latch
has a hole to allow a padlock to securely
protect valuable samples.
• Control panel with digital
display for easy opera-
tion.

ACCESSIBILITY
• A beak style inner
door latch tightly
closes the inner door
against the freezer
frame. It also helps make opening and
closing the door smoother.
• The condenser filter is situated at the
bottom right side of the front panel to
make filter removal and cleaning easier.
RELIABILITY
• Status Alert (Condition monitor)
Monitors ambient and system conditions
continuously and notifies of any abnor-
malities before a problem happens.
EVOLUTIONARY DESIGN
• SANYO V.I.P.™ Evolution Series -86˚C
ultra-low temperature freezers use
patented revolutionary vacuum insulation
cabinet construction that reduces the
wall thickness from 14cm to 7cm (5.5”
to 2.7”) and achieves up to 30% more
storage capacity than a conventionally
insulated freezer without increasing the
footprint.
• The newly developed refrigeration
system and the freezer structure offer a
quiet experimental environment.
• Achieves 10% higher energy conserva-
tion than previous model. (For model
rated 220V, 50Hz)
• The newly developed back cover
combined with new aerodynamically
designed and placed components in the
refrigeration compartment provide supe-
rior air flow, making it possible to drasti-
cally reduce the stress on the freezer
and contributing to excellent durability.
• Two independent and insulated inner
doors with gaskets prevent cold air leak-
age.

•Appearance and specifications are subject to change without notice.
*Cooling performance is indicated by the temperature reached at
the center of the freezer (at ambient temperature of 30°C with no
load). In order to use the freezer at a stable temperature for a long
time, it is recommended that the temperature be set to at least
5°C higher than the indicated lowest temperature.
In addition, depending on the usage conditions, it may not be
possible to reach the indicated lowest temperature.
