Biomedical Freezer

  • What is the difference between Direct Cooling Type and Fan-assisted (Fan Cooling) Type of Biomedical Freezer (-30°C/-40°C) ?
    Generally, it can be said that following features each cooling type has. Please note that below is the general information and actual performance depends on individual product. Checking each performances, specifications and features are recommended.

    The Fan Cooling Type generally requires air passage for the wind generated by fan that may reduce the effective internal capacity. Temperature reaction / change as well as pull-down speed is faster with forced air circulation by fan. Regarding frost, Fan type performs cycle defrost automatically and removes chamber frost before accumulated inside. Alternative running of compressor and heater for automatic cycle defrost may increase power consumption. Also, some temp. rising occurs during automatic defrost.
    For more details of the performance and specification of our Biomedical Freezers line-up, find the brochures and operational manuals.
Cooling Type of Freezer Direct Cooling Type Fan-assisted Type
Effective capacity Larger Smaller (caused by air passage)
Chamber temp. change reaction Slower Quicker
Temperature pull-down Slower Quicker
Amount of frost built chamber inside More Less
Defrosting method Natural defrost by turning OFF the unit power Automatic defrost during compressor stopped
Temperature rising during defrost No effects on sample which to be removed temporarily Some temp. rising occurs
Power consumption Less More

Pharmaceutical Refrigerator

  • What is the difference between Professional Pharmaceutical Refrigerators and Household (home) Refrigerators?
    Generally, it can be said that following differences on specifications each equipment has. We recommend to use the Professional Pharmaceutical Freezers for valuable medication / vaccine storage because of the reasons below;-
    - Inside temperature is affected by ambient temperature
    - Risk for freezing of stored medication / vaccine
    - Variation and instability of of internal temperature uniformity
    - Internal temperature rising during defrost
    - Precise temperature control of chamber inside is impossible
    - Alarms and safety functions are not available
    Please note that below is the general information and actual performance depends on individual product.  
    For more details of the performance and specification of our Pharmaceutical refrigerators line-up, find the brochures and operational manuals.
