High Stage Compressor Failure

Freezer Fails

No high or low stage used. Two refrig-

eration systems, each with a separate 

compressor, operate independently in 

overlapping cycles during normal op-

eration. If one compressor fails internal 

temperature is maintained indefinitely 

at -65°C with backup compressor.

Reduced Power Consumption

The SANYO Twin Guard Series

 Freezer 

can be set for Normal or EcoMode

 

operation, depending on ambient tem-
perature and load. EcoMode

 is recom-

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.
