Features
EVOLUTIONARY DESIGN
• SANYO V.I.P.™ Evolution Series -86˚C
ultra-low temperature freezers use
patented revolutionary vacuum insula-
tion 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 conven-
tionally insulated freezer without increas-
ing the footprint.
• The newly developed refrigeration
system and the freezer structure offer a
quiet experimental environment.
• Achieves 12% higher energy conser-
vation than previous model. (115V, 60Hz)
• The newly developed back cover com-
bined with new aerodynamically design-
ed and placed components in the
refrigeration compartment provide
superior air flow, making it possible to
drastically reduce the stress on the
freezer and contributing to excellent
durability.

• Two independent and insulated inner
doors with gaskets prevent cold air
leakage.
RELIABILITY
• Status Alert (Condition monitor)
Monitors ambient and system conditions
continuously and notifies of any
abnormalities before a problem happens.
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.

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.

*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.
