-86ºC Ultra-low Temperature Freezer, Dual Refrigeration system for standby

Idea for long term preservation of virus, germs, vaccines, biological tissues and organs, special food, medicines, reagents and etc. Dual Refrigeration system Freezer is suitable for scientific research institutions, hospitals, sanitation and antiepidemic stations, electronics, chemical industries.

Refrigeration system

  1. VIP + special PU foam insulation thickness 150mm
  2. Dual cascade refrigeration system, perfect refrigeration performance even under 43°C ambient temperature.
  3. Almost all the components related to cooling system can be replaced & repaired to ensure long life of products.
  4. Used Temperite oil separator, Tecumshe compressor and CFC-free refrigerant

Temperature controller    

  1. Microprocessor based temperature controller, touched digital display panel, reveal the status of freezer precisely and clearly.
  2. Three months temperature and alarm conditions can be read from USB port
  3. Optional wifi monitoring module and exclusive software to realize remote monitoring

Security

  1. Alarms: High and low temperature, high ambient temperature, sensor error, power failure, high & low voltage, low battery, door jar, High/low temperature, Filter checking, Condenser failure
  2. Buzzing and flashing alarm, remote alarm port and message alarm(optional)
  3. Special designed alarm system, buzzing will resume after long time of failure not modified, though mute button pressed.
  4. Back-up battery can keep alarming for 72h after power failure
  5. Battery life alerts can prompt the user before need replacing
  6. Keyboard lock and password protection, prevent parameters being modified randomly
  7. Power-on delay: When power restores, all devices would kick-off at one time, which could cause great impact to the power network, could lead to circuit breaker tripping. The delay start function would protect the equipment and make sure all devices operate normally.
