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  
Seriesintroduces 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

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 SeriesUltra-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 Seriessatisfies  
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 Seriesis 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 EcoModedeploys 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.

In 2006, RoHS (Restric-  
tion of Hazardous Sub-  
stances) legislation (EU  
Ultra-low freezers are often located  
within research and hospital laboratories  
or production facilities. Users prefer  
close proximity for easy access to valu-  
able stored products.  
Directive 2003/95/EU)  
became effective. RoHS relates to the  
restriction of hazardous substances and  
reductions in environmental pollution.  
If operating noise from refrigeration  
compressors is excessive, and/or  
compounded by installation of multiple  
freezers in adjacent locations, the  
working environment is severely  
compromised.  
Through RoHS legislation the EU and  
other participating countries are banning  
toxic substances in electrical equipment  
such as lead, cadmium, mercury, chro-  
mium 6+, PBB and PBDE.  
An Easy-In/Easy-Out outer door latch  
permits one-handed operation. A  
locking provision is designed for use  
with a conventional padlock.  
SANYO has included advanced noise  
abatement in all contemporary ultra-low  
freezers and noise reduction levels are  
well below those of competitive freez-  
ers. Data is available upon request.  
While compliance with this legislation  
has posed a significant challenge for  
SANYO, all SANYO ultra-low freezers and  
components are now 100% compliant  
to RoHS standards.  
A universal keyed door lock prevents  
the outer door from opening.  
The outer door closes uniformly  
against a multi-point gasket to form  
a tight seal and prevent moisture  
migration leading to frost or ice build-  
up.  
Electrical Standards  
All SANYO products including ultra-low
