Conventional
cascade refrigeration systems, used by many manufacturers in
Ultra low Temperature Freezers, cannot perform in the event
of one of the compressors failing. This can lead to the
potential loss of samples due to loss of freezing ability.
However, greater sample protection is provided with the new
SANYO MDF-U500VX ULT Freezer because it can still maintain a
temperature in the -70C range continuously even if one of
its compressors fails.
The
MDF-U500VX uses SANYO’s unique Twin Guard Dual Cooling
Technology to provide freezing down to -86C with exceptionally
good temperature distribution throughout the freezer’s storage
chamber. Dual Cooling Technology does not require a conventional
cascade refrigeration system to achieve temperatures of -86C.
“Dual Cooling compressors” work independently of each other
unlike cascade systems where two compressors are reliant on each
other to achieve ultra low temperatures. This means that cooling
can still be provided in an MDF-U500VX even if one compressor
fails, because each compressor is not reliant on the other. A
temperature in the -70C range is continuously maintained if only
one compressor is working, which not only protects your samples
longer than in a conventional freezer, but also allows you more
time to arrange service visits and contingencies.
