Main characteristics of the product:

Forefront Refrigerating Techniques:

Refrigerating medium numbered as "China 70-1", which was invented by the Physics and Chemistry Institute, China Academy of Science and meets environmental requirements completely, was applied.

The result has passed state-level appraisal attended by five famous academicians.(Patent No. in China: ZL02117656.6)

The unique refrigerating technique of refrigerating circuit and monopole oil-lubricated compressor, whose patentright belongs to China, was applied.(Patent No. in China: ZL00136709、ZL00267777.6)

The two-time foaming technique is used and it can protect isolation layer from being damaged by low temperature, which is in the world's lead in the aspect of temperature conservation;

150mm thick of insulation course has good temperature-conserving effect;

The high-efficiency compressor with internationally famous brand of Electrolux, is imported from Spain;

German fan electromoter with internationally famous brand of Ebm is used.

Sophisticated controlling technique:

Highly accurate computerized temperature-controlling system, platinum resistance transducer is used;

The temperature ranging from -40℃ to -86℃ in the case can be set freely;

The temperature is shown digitally, and the running state is clear;

There are functions to lock keyboard and to keep code, so to prevent running parameter from being changed randomly;

Perfect sound-light warning system (for high temperature, low temperature, low voltage, door-opening, blocked screen and system failure), so as to ensure the safety of the kept articles in the case;

There is a function for adapting a temperature-recording typewriter and reserve batteries;

There is a function for adapting warning lights and distant concentrative warning system.

Humanized designing:

The door can lock automatically, and it is easy to open it;

The safety lock can prevent random opening;

Adjustable shelves are convenient to place articles;

The double-layered door can keep cold air, and has good temperature-conserving effect.
