Refrigeration System

The Twin Guard Series ultra-low freezer
™
avoids conventional cascade refrigera-
tion technology by using two completely
independent one-compressor, autocas-
cade cooling systems, each capable of
maintaining ultra-low temperatures.

Integrated LCD Control with
Graphical Display
The Twin Guard Series
is managed by an integrated micropro-
cessor controller with LCD information
center to simplify all freezer func-
tions. Uniform ultra-low temperature
is achieved through a combination of
performance systems supervised by the
controller complete with alarm, program-
ming and diagnostic protocols.
Patented V.I.P .
Vacuum Panel Insulation
Combination of multiple high-perfor-
mance vacuum panels with high-density
foam insulation achieves thin-wall profile
for maximum interior volume in a com-
pact footprint. Increased cooling capacity
improves temperature recovery after
door openings.
SANYO V.I.P. Series freezers offer high-density
™
storage that effectively reduces the volumetric unit
costs of ultra-low storage.

Inner Doors Improve Uniformity
Easy-In/Easy-Out SANYO Eagle
™
door latches feature ergonomic design
to seal firmly against the cabinet with
one hand. High-strength, insulated inner
doors help minimize change in interior
temperatures during routine door
openings.
Reduced Power Consumption
The SANYO Twin Guard Series
can be set for Normal or EcoMode
operation, depending on ambient tem-
perature and load. EcoMode
™
mended for 90-95% of applications.
Although both refrigeration systems are
completely independent, EcoMode
establishes an overlapping cycle to
significantly reduce energy consump-
tion while optimizing interior uniformity
from top-to-bottom and front-to-back for
protection of high value materials.
