Construction
Advanced ultra-low temperature refrigeration system
The SANYO cascade refrigeration system is specifically designed for
ultra-low temperature applications and offers superior performance
and durability, even in high ambient temperatures and in response to
frequent door openings. The cooling system maintains uniform
temperatures with quiet, energy efficient operation.
Accurate microprocessor temperature control
The SANYO microprocessor control system utilises SANYO made
electronic components to ensure precise and reliable ultra-low
temperature operation.
Easy-access filter
The condenser filter is situated
at the bottom right side of the
front panel to make filter remov-
al and cleaning easier. (Except
MDF-C8V which is filter-less)
Safety
Alarms
• An alarm lamp and buzzer offer secure warning of power failure or
abnormal temperature increase. In addition, battery back-up allows
the internal temperature to be checked during a power failure.
• High and low temperature warnings provide 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 the buzzer resumes opera-
tion, should alarm conditions continue after it is silenced.
• Remote alarm terminals are also provided as standard equipment
for individual or group control.

Status alert
For improved reliability, Status alert function monitors ambient and
system conditions continuously and notifies of any abnormalities
before a problem occurs.
Notifications
A battery life notification function is also provided to notify users of
accumulated battery time.
Self diagnostic
The temperature sensor, filter sensor and cascade sensor monitor
operation conditions continuously. Should an abnormality be picked
up, an error code and the current freezer temperature will be dis-
played in turn.
Tamper proof
To prevent unauthorised access to freezer settings, a key-lock func-
tion is provided that blocks changes being made through the keypad.
Delay start
On power failure recovery, typically every unit in the lab will try to
start-up simultaneously. This can create a significant drain on the
electricity supply and a drop in voltage that may cause the breaker
to trip again. SANYO’s exclusive compressor start-up delay function
enables compressor startup during recovery after a power failure to
be delayed for several minutes, in order to
reduce and distribute the sudden electrical
load during recovery and enable smooth
restarting of laboratory operations. Start-up
delay is programmable from 2 to 15 min.
The advantage of this system is that the
start-up of multiple freezers can be stag-
gered over a period of up to 15 minutes,
which provides an even electrical load on
power failure recovery.
Reliability
Filter-clog check
A microprocessor controlled filter check function protects the
refrigeration circuit by notifying the user of a blocked condenser
filter via an alarm lamp. (Except MDF-C8V which is filter-less).
Frost reduction
SANYO’s unique combination of a “hot
line”, routed around the door seal, and
insulated inner doors provide an excellent
airtight seal which prevents ice build-up
around the door.

Data acquisition
The SANYO DAQ system,
SANYO’s original data acquisi-
tion software, enables remote
setting and monitoring of VIP
freezers. (Option)
Patented VIP insulation technologies
SANYO pioneered a revolutionary vacuum insulation cabinet
construction that reduces the wall thickness to approximately one
half and achieves up to 30% more storage capacity than a
conventionally insulated freezer without increasing the footprint. VIP
Insulation maximises storage capacity when space is limited. When
using multiple units, large amounts
of space can be saved compared to
conventionally insulated freezers.

Full suite of sample protection measures
Advanced design, construction and control features provide added
safety for valuable specimens.
• New double type lid gasket ensures an effective seal and suppresses
cold air loss.
• New VIP PLUS insulation material improves the insulation perfor
mance of the cabinet.
• Equipped with new Status alert function.
• Equipped with LN2backup system as standard to prepare for any
contingency.
Simplified high-efficiency
refrigerating system
• Use of a newly developed single-com-
pressor system achieves an approxi-
mately 40% reduction in power con-
sumption.
• Low-noise design provides quiet, unob-
trusive operation ideal for in-lab use.
New cooling circuit enables filter-less design
Filter-less design makes the routine maintenance procedure of
cleaning the condenser filter unnecessary.

Perfect size for personal use
Using ultra-low tempera-
ture freezer storage for
long-term preservation of
valuable specimens elim-
inates worries of contam-
ination, reduces running
costs, and enables long-
term storage at ultra-low
temperatures far below
the recrystallization point.
Easy-to-use tight-sealing door latches
• The rugged, one-handed operated outer door
latch can accommodate a padlock for added
protection of valuable samples.
• 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.

Specifications
*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.
