to continue to run continuously at
-65°C in the unlikely event of one
compressor failure.
• The combination of additional refrigeration intelligently managed by intuitive
microprocessor controls and integrated
into SANYO’s patented V.I.P. PLUS
vacuum panel cabinet make the most
efficient use of available floor space.
• Twin Guard Series™ freezers significantly increase ultra-low protection
while minimizing energy costs
through a unique EcoMode™ function.
EcoMode™ optimizes power consumption by orchestrating run times
for each refrigeration system in response to cooling demands.

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
with optional CO
or LN2 backup sys-
