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

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.

Status alert

For improved reliability, Status alert function monitors ambient and
system conditions continuously and notifies of any abnormalities
before a problem occurs.

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.

Hot line

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 opera­tion, should alarm conditions continue after it is silenced.

• Remote alarm terminals are also provided as standard equipment
for individual or group control.

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 dis­played in turn.

Tamper proof

To prevent unauthorised access to freezer settings, a key-lock func­tion 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 stag­gered over a period of up to 15 minutes,
which provides an even electrical load on
power failure recovery.

Cabinet Construction

Insulated inner doors with gasket
offer additional protection during door
opening and improve overall energy
efficiency in response to ambient
temperature change.

Easily removable inner doors

Inner doors are removable to allow
easy cleaning and defrosting.

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.

*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.
