These ultra-low temperature freezers maintain internal temperatures
as low as -86°C (-123°F) at an ambient temperature of +30°C (86°F). They
are ideally suited for use in hospitals and laboratories, in long-term
preservation and storage of blood, specimens and components and in
testing of various types.
Panasonic produces several models of ultra-low temperature freezers that
can achieve and maintain refrigeration down to -86°C (-123°F) at an
ambient temperature of 30°C (85°F) Our wide selection and variety of
sizes and refrigeration capacities are suitable for uses such as
long-term preservation, testing of various types and frozen storage.
In the process of solving various technical problems to achieve and
maintain ultra-low temperature, Panasonic designed a compressor for
ultra-low temperature use.
In ultra-low temperature freezers, effective insulation is critical
since the temperature difference between the outside and the inner
compartment can be as high as 115°C.
The temperature inside the freezer can be set and monitored easily by
means of an accurate microprocessor temperature control with digital
display. The thermostat utilizes a platinum resistor sensor that is
precise and extremely durable.
In case of power failure or an irregular rise in temperature, a
rechargeable, battery-operated indicator lamp and alarm will be
Chest-type freezers can maintain relatively stable inner
temperatures. Moreover, their low-profile design makes the placement and
removal of contents very convenient.
