-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.
