-86°C PRODUCT FAMILY

A wide range of Ultra-low temperature freezers.

This product family offers different types and models of ultra-low freezer which can achieve and maintain temperatures down to -86ºC (-123ºF) at ambient temperature of 30ºC (85ºF). It is a wide selection, offer- ing a variety of sizes and types suitable for uses such as long term preservation, testing, frozen storage etc.

Specially Designed Compressor for Ultra-Low Temperature.

The refrigeration system is at the heart of producing ultra-low temperature freezing. In the process of developing various technical solutions in order to achieve and maintain ultra-low temperatures, Sanyo designed a compressor especially for ultra low-temperature use. Sanyo is a leading manufacturer of ultra-low temperature freezers that develops and produces all its own components, from the refrigeration units to the microprocessors.

and the “Hot Line”.

In Ultra-Low temperature freezers, effective insulation is extremely critical since the temperature difference between the outside and the inner compartment

DESIGN

can be as high as 115ºC. The insulation used in Sanyo’s ultra-low temperature freezers is two layers of rigid,

foamed in place polyurethane. This design prevents the insulation layers from distortion and cracking that might occur due to temperature differences inside and out, and creates the most efficient insulation material available today. Moisture condensation at the top edges of the cabinet due to differences in temperature inside and out causes frost and icing problems, which may reduce heat insulation efficiency and obstruct door movements. They are prevented by the “hot line” by means of which hot gas from the higher temperature circuit is circulated through the problem areas.

Evolutionary Design

■The newly developed refrigeration system and freezer structure minimizes intrusive operating noise.

■The newly developed back cover combined with new aerodynamically designed and placed components in the refrigeration compartment provide supe- rior air flow, making it possible to drasti- cally reduce the stress to the freezer and contributing to excellent durability.

■Two independent and insulated inner doors ensure maximum interior chamber uniformity.

Safety

■High and low temperature warning pro- vides an audible and visual alarm when the temperature deviates more than ±5°C to ±20°C (adjustable) from the set point.

■Alarm ring back function ensures that buzzer will resume operation, should alarm conditions continue after it is silenced.

■Microprocessor-controlled filter-clog check function

protects the refrigeration circuit.

■Control panel with digital display for easy operation.
