-86°C PRODUCT FAMILY DESIGN
A wide range of Ultra-low
temperature freezers.
This product family offers different types
and models of ultra-low freezer which can
achieve and maintain temperatures down
to -86ºC (-123ºF) at ambient temperature
of 30ºC (85ºF). It is a wide selection, offering a variety of sizes and types suitable
for uses such as long term preservation,
testing, frozen storage etc.
Specially Designed Compressor for
Ultra-Low Temperature.
The refrigeration system is at the heart of
producing ultra-low temperature freezing.
In the process of developing various
technical solutions in order to achieve and
maintain ultra-low temperatures, Sanyo
designed a compressor especially for ultra
low-temperature use. Sanyo is a leading
manufacturer of ultra-low temperature
freezers that develops and produces all its
own components, from the refrigeration
units to the microprocessors.
can be as high as 115ºC. The insulation
used in Sanyo’s ultra-low temperature
freezers is two layers of rigid,
foamed in place polyurethane. This design
prevents the insulation layers from
distortion and cracking that might occur
due to temperature differences inside and
out, and creates the most efficient
insulation material available today.
Moisture condensation at the top edges
of the cabinet due to differences in
temperature inside and out causes frost
and icing problems, which may reduce
heat insulation efficiency and obstruct
door movements. They are prevented by
the “hot line” by means of which hot gas
from the higher temperature circuit is
circulated through the problem areas.
UPRIGHT -86ºC ACCESSIBILITY
Evolutionary Design
■
The newly developed refrigeration
system and freezer structure minimizes
intrusive operating noise.
■
The newly developed back cover
combined with new aerodynamically
designed and placed components in the
refrigeration compartment provide superior air flow, making it possible to drastically reduce the stress to the freezer and
contributing to excellent durability.
■
Two independent and insulated inner
doors ensure maximum interior chamber
uniformity.
An Ideal Freezing Environment By
Means of A Double-Insulation Wall
and the “Hot Line”.
In Ultra-Low temperature freezers,
effective insulation is extremely critical
since the temperature difference between
the outside and the inner compartment

Safety
■
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.
■
Control panel with digital display for
easy operation.

Accessibility
■
A new rugged inner door latch tightly
closes the inner door and makes accessing chamber contents easier.
■
The condenser filter is located at the
bottom right side of the front panel to
make filter removal and cleaning easier.
■
Alarm lamp and buzzer offer secure
warning of power failure or abnormal
temperature increase.
■
New rugged, one-handed outer door
latch has a hasp to allow a padlock for
additional security
SAFETY & ALARM
Built-In Temperature & Power Failure
Alarms(Lamp/Buzzer).
In case of power failure or an irregular rise
in temperature, a rechargeable, Cadnica
battery-operated indicator lamp and alarm
will be activated. Optional CO2 and LN2
back-up systems are available and are
self-activated when a power outage occurs. This equipment helps ensure that the
contents will be protected in the event of
any power failure or mechanical trouble.
Easy to Operate.
Overall operability and dependability are
greatly enhanced by improved design
details. Highly durable hinges are used to
support the large door so both opening
and closing are facilitated. Door handles
are equipped with a latch-locking system.
A Wide Range to Choose From Large,
Small, Chest and Upright- A freezer to
suit your needs.
Chest type freezers low profile design
makes the placement and removal of
contents very convenient. The upright
type is designed to accommodate a large
capacity in a limited space. Even very
narrow spaces can be readily utilized.
RELIABILITY & CONTROL
A Special Refrigerant and Oil to
Maintain Stability and Reliability.
In order to expand refrigeration capacity,
a special compound refrigerant has been
used. This refrigerant relieves the
refrigeration system of much of its load by
evaporating at a lower temperature level
within the circuit. Also, a special grade of
refrigeration machine oil is used that offer
superior properties of high rate of
recovery and outstanding resistance to
heat and wear. This contributes to the
long life and dependability of the freezer
unit as a whole.
Microprocessor Temperature Control
With Digital Design.
The temperature inside the freezer can be
set and monitored easily by means of
precise microprocessor temperature
control with digital display. The thermostat utilizes a platinum resistor
(Pt 100) sensor which is precise and
extremely durable.

*Cooling performance is indicated by the temperature reached at
the center of the freezer (at ambient temperature of 30C 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 5C
higher than the indicated lowest temperature.
In addition, depending on the usage conditions, it may not be
possible to reach the indicated lowest temperature.
