SANYO's MDF Series
Freezers offer the
outstanding reliability
and performance
required in a wide
variety of cold
storage and research
applications.

In the biotechnology field, freezers

provide effective storage of enzymes for
genetic research as well as culture media,
reagents and samples for testing. In the

industrial field, they are ideal for ageing and
temperature tests on electronic components,
precision devices, and compound resins. In
the medical field they provide effective storage
of life-saving blood products and vaccines, as
well as samples for diagnosis. As a storage
environment, with excellent safety features,
easy operability, and a host of other features,
these freezers offer unsurpassed reliability.

-30°C/-20°C BIOMEDICAL FREEZERS

• SANYO MDF Series biomedical freez­ers offer outstanding reliability and
performance for a wide variety of storage
and research applications.

• “Plug-in and Go” Laboratory Grade
freezing for safe storage of enzymes,
vaccines, and other biologics that are
designed with all the features required
for biomedical research and biotechnol­ogy applications.

• If you are looking for precision tem­perature controlled storage environment,
look to SANYO.

ENHANCED OPERATION

Enhanced Operation

• Front mounted display/control panel

• LED Temperature display

• The chamber temperature is displayed
for five seconds if BUZZER key is de­pressed during power failure alarm

• After a power outage, operation
resumes at pre-outage settings (non-vola­tile memory for temperature and alarm
temperature settings)

• Calibration is possible through the
control panel.

• Access ports

• Casters and adjustable feet

ENHANCED OPERATION (CONT.)

Auto Defrost (MDF-U730)

• Storage at -30°C with auto-defrost
with consistent temperature control
below -20°C during defrost cycle .

• Precision temperature uniformity
throughout chamber due to forced air
circulation with dual fans.

• Evaporator (Cooling Coils) provide the
cooling effect and are located at the top
of the inner chamber.

• Air flow inlets and outlets direct the air
flow across the evaporator to cool the air.

• Dual Circulation fans add to excellent
overall uniformity (uniform temperatures)
inside the cabinet.

FEATURES

Temperature Recording Features
(Optional)

A temperature recorder can be fitted in
convenient position that will not interfere
with installation.

• 7-day circular recorder (MTR-C954,
MTR-C955)

Environmentally-Friendly

• HFC refrigerant R-404A (non-CFC, non­HCFC refrigerant) is environment-friendly
and offers superb performance.

• Pre-coated metal body causes less
environmental damage than conventional
paint coating.

FEATURES

Safety Features

• Alarm & Recording System

• High/low temperature alarm (±5°C to
±15°C, adjustable)

• Power failure

• Remote alarm contacts

• Self diagnostics with error messages

Sanyo designed and built rotary compres
sor offers high performance, reliability
and peace of mind. Heated mullion under
door gasket prevents frost build up.

Balance Hinge allows free choice of
opening angle (chest type)

To make this chest freezer easier to use,
the balance hinge keeps the door open
at whatever angle chosen, leaving both
hands free to work.

Lockable door latch for extra secu­rity (upright type)

All units come with universal key locks
and the upright freezers come with an
additional lock. By adding a commercial­ly available lock, you can safeguard the
contents of the freezer and keep hazard­ous items out of harm's way.

Manual Defrost Enzyme & Biologics
Preservation

• Storage at -30°C and -20°C easily with
constant stable control.

• Uniform temperatures through out
chamber

• Because there is no defrost cycle,
the inner chamber temperature remains
stable.
