Most Energy Efficient
World leading power consumption, only 8 Kwh/day

Low Noise
Innovative refrigeration cabin design reduces operational noise

Reliable Performance
Cabinet temperature can reach -86ºC with temp uniformity within 6ºC


 

Minimal Noise Output
Adaptive control technology controls fans
and compressors to reduce noise levels to an
exceptional 43.5dB.


Frequency Conversion Adaptive    
Unlike standard, single speed compressors
conversion compressor runs at variable
speeds to adjust cooling performance to
the conditions inside and outside of the
freezer. It allows the freezer to adjust to
factors such as start-up and door openings
when a higher compressor speed is needed.
When conditions are normal or stable,
the drive runs at a lower speed while still
protecting the samples.



Precise Temperature Control    
The innovative control algorithm
balances the effects of temperature loss
with the unique frequency conversion
refrigeration system, ensuring the
cabinet temperature stability of ±3°C.
