Refrigeration System
The Twin Guard Series™ Ultra-Low Freezer avoids conventional cascade refrigeration technology by using two completely
independent one-compressor, autocascade cooling systems, each capable of
maintaining ultra-low temperatures.
• Each refrigeration circuit includes a
closed-loop cold-wall evaporator configured 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 mutually dependent high- and low-stage
systems.
• 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.
• In the event of a facility power failure

• An Easy-In/Easy-Out outer door latch
permits one-handed operation. A
locking provision is designed for use
with a conventional padlock.
• 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 buildup.
• The interior inventory system is based
on a center shelf and two latching
insulated inner doors designed for
one-handed operation. Inner doors
minimize exposure during routine
door openings.
• The two primary compartments can
be sub-divided by adjustable shelves
to accommodate standard stainless
steel inventory racks for 2” or 3”
boxes (see Accessories).
• Rounded interior corners enhance
temperature uniformity and simply
cleaning and decontamination when
required.

RoHS Compliance
In 2006, RoHS (Restriction of Hazardous Substances) legislation (EU
Directive 2003/95/EU)
became effective. RoHS relates to the
restriction of hazardous substances and
reductions in environmental pollution.
Through RoHS legislation the EU and
other participating countries are banning
toxic substances in electrical equipment
such as lead, cadmium, mercury, chromium 6+, PBB and PBDE.
While compliance with this legislation
has posed a signicant challenge for
SANYO, all SANYO ultra-low freezers and
components are now 100% compliant
to RoHS standards.
Electrical Standards
All SANYO products including ultra-low
temperature freezers are tested and certified by an NRTL (National Recognized
Testing Laboratory) to assure compliance
with US and International standards for
electrical safety prescribed in
29 CFR 1910.7( c ).
MDF-U5 00V XC MDF-U70 0VXC
Noise Reduction
Ultra-low freezers are often located
within research and hospital laboratories
or production facilities. Users prefer
close proximity for easy access to valuable stored products.
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.
SANYO has included advanced noise
abatement in all contemporary ultra-low
freezers and noise reduction levels are
well below those of competitive freezers. Data is available upon request.
