86°C ULT Freezer-

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

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.

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.
