Ultra Low Temperature Freezer – QT-TFF

Ultra Low Temperature Freezer – QT-TFF

Parent Product
Environmental Chambers

Best Application: Ultra-cold freezer (-86°C/-40°C) used for storage of blood cells, biological products, pelagic products, a low-temperature test of electronic devices and special materials, etc.


 

Applications

Ultra-low temperature freezer (-86°C/-40°C) used for research institutions, automotive Industry, universities, companies, and hospitals. The ultra-low freezer -86°C suitable for scientific research institutes, disease prevention, and control, colleges and universities, biological engineering, hospitals, blood stations, ocean fishing, and electronic chemical industry, etc. 

The -86°C ultra-low freezer using France Tecumseh compressors, High-power direct cooling refrigeration system, Efficient and thick insulation metal case. When the temperature range between -86°C ~ -40°C, It can set an arbitrary value, through the professional temperature control system, temperature difference control in the range of ±2°C. The -86°C ultra-low temperature freezer has the characteristics of compact structure, fast cooling, stable operation, and convenient operation.

Features/Advantages
  • LED display screen can display the temperature inside the -86°C ultra-low temperature freezer, setting temperature, environment temperature, input voltage, high and low-temperature alarm, and temperature inside the -86°C ultra-low lab freezer, with fault warning function.
  • Ultra-low temp freezer with adjustable shelf design, easy to access items. Ultra-low freezer used one-piece door lock handle and compact caster design, more flexible and convenient.
  • Super low-temperature freezer includes condensing fan intelligent start and stop, effective energy saving.
  • With network, remote alarm function, and high and low voltage automatic compensation function, advanced and practical.
  • Optional freezing-storage box, freezing-storage rack, disc recorder, RS232, and 485 interfaces. Low-temperature freezer with more freezer boxes per unit area, lower storage cost.
  • For the old building door width of 750mm, box design width of 725mm, easy to enter the door, small footprint.
  • Four layers of insulation, four doors independent seal. The door can effectively prevent the leakage of the air conditioner, which is safer and more energy-saving.

Advantages

Temperature Control

Ultra low temperature freezer principle. Computer control, temperature digital display, adjustment unit is 1℃, the temperature in the box -40°C ~ -86°C adjustable.

Ultra low temp chest freezer can send the alarm information on the device to the registered mobile phone users in the form of SMS

Users can send SMS messages to the equipment to inquire real-time temperature and alarm situation. As long as there is a mobile phone signal, it can monitor the device remotely anytime and anywhere.

Refrigeration System

Optimization of cascade refrigeration technology, imported compressor, better refrigeration capacity. Super thick and high density insulation layer, good insulation effect.

Ultra low temperature laboratory freezer unique four seal structure and heat insulation system design, effectively eliminate frost phenomenon.

The specially designed low temperature stage computer control avoids the wrong control of low temperature stage compressor by the superposition system.

Security System

Various fault alarms (high and low temperature alarm, sensor alarm, power failure alarm, high and low voltage alarm, condenser cooling difference alarm, ring temperature overshoot alarm)

Multiple protection functions (password protection, power-on delay protection, ultra-low voltage compensation protection, ultra-high voltage compensation protection)

Ultra low temperature freezer maintenance. Two alarm modes (sound beeping alarm, light flashing alarm). All independent parts are safely grounded.

Various Fault Alarms

High and low-temperature alarm, power failure alarm, low battery power alarm, high ambient temperature alarm, condenser dirty alarm, over-voltage alarm, sensor fault alarm, etc., to ensure safe use.

Three Alarm Modes

Sound beeping alarm, light flashing alarm, and remote alarm. Start time delay, Stop interval, and other protection functions. Keyboard lock and password protection to prevent arbitrary adjustment of parameters.

Optimization of cascade refrigeration technology, unique evaporation, and condensation heat transfer system design, refrigeration capacity is stronger.

Small low temperature freezer has no fluorine foam, no fluorine refrigerant, green environmental protection. Super thick insulation layer, internal and external double doors, multi-layer sealing structure design, lock the air conditioner, good insulation effect.
