The SANYO MDF-500VXC and MDF-U700VXC Twin Guard Series™ ultra-low freezers are designed for -86°C storage of high-value biologicals.
Ideal for critical material storage in repositories, highly secure BSL3/4 labs, hospitals, clinics and medical research facilities. The Twin Guard
Series™ introduces the concept of dual, independent, auto cascade refrigeration systems contained within a single cabinet.

Highly sensitive to temperature fluctuations or
uneven storage temperatures at different positions
within the interior chamber.
Enhanced temperature uniformity, top-to-bottom,
front-to-back, assures sample stability at all
inventory locations.
Restricted access to the contained laboratory
limits serviceability.
Twin Guard Series™ extends critical time necessary
to react in the event of mechanical failure.

Twin Guard Series™ -86 Dual°Cool
Refrigeration System
• In the unlikely event of a compressor
failure in one system, the remaining
system will automatically maintain a
minimum of -65°C for an indefinite
period.
TheTwin Guard Series™ Ultra-Low Freez-
er avoids conventional cascade refrigera-
tion technology by using two completely
independent one-compressor, autocas-
cade cooling systems, each capable of
maintaining ultra-low temperatures.
The SANYOTwin Guard Series™ satisfies
the industry demand for safe, long-
term storage for the most high-valued
materials. Two independent refrigeration
systems, combined with optional liquid
nitrogen or liquid CO2 back-up systems,
offer a circle of protection unmatched in
the marketplace. Developed for use with
conventional inventory racks and boxes,
theTwin Guard Series™ is ideal for stor-
age of sensitive stem cells, embryos,
cell lines, and other rare specimens.
• In the event of a facility power failure
with optional CO2 or LN2 backup sys-
tem installed, the freezer will maintain
-65°C storage temperature for up to
eight hours (CO2 backup system) and
-65°C storage temperature for up to
15 hours (LN2 backup system).
• Each refrigeration circuit includes a
closed-loop cold-wall evaporator con-
figured in parallel to the other.
• Independent evaporators and cooling
fans assure back up status at all times,
eliminating system failure due to
sub-component failure in conventional
cascade systems configured of mutu-
ally dependent high- and low-stage
systems.
• A unique EcoMode™ deploys both sys-
tems in overlapping cycles to maintain
-86°C and to reduce energy consump-
tion by as much as 15%.
• Evaporator coils embedded in the pat-
ented, high-tech, SANYO V.I.P. PLUS™
vacuum-insulated thin-wall cabinet are
strategically oriented to deliver the
best temperature uniformity at all shelf
levels, top-to-bottom and front-to-back.
• New SANYO-designed Cool Safe™
refrigeration compressors feature inno-
vative refrigerant feedback processes
to reduce compressor temperature,
thereby extending compressor life and
minimizing heat output.
Independent systems efficient ultra-low cooling is
achieved through two independent evaporator circuits
surrounding the interior chamber.

restriction of hazardous substances and
reductions in environmental pollution.

Through RoHS legislation the EU and
other participating countries are banning

While compliance with this legislation
has posed a significant challenge for
