Ultra-low temperature
- The minimum temperature of the refrigerator can be switched from 0 to minus 86°, and the precise temperature control panel
- Stirling new compressor - a wide range of temperature Settings than traditional compressors: +18 ° C ~ -86 ° C, other traditional low temperature refrigerators can not reach
- Using a Stirling Engine for cooling, this freezer has higher efficiency, lower power consumption, lower weight and a smaller size compared to a traditional freezer.
- A Stirling engine is a heat engine that is operated by the cyclic compression and expansion of a gas between different temperatures, resulting in a net conversion of heat energy to mechanical work.
- Ultra-low temperature refrigerators are PID control programs that need a balance between cooling and temperature control. The closer to the set temperature, the less cold output of the compressor, the configuration of high-precision probe, real-time monitoring of the temperature, temperature difference control within ±1℃.
- LABFENG laboratory ultra-low temperature refrigerator, program Settings not only pursue cooling, but also pursue the ability to control temperature. This upgraded product can definitely meet the needs of accurate temperature control
Upgrade 22L Large Capacity - Larger Capacity Than 20L(B09QSSCH9C/ B0C5HPYG5L) Ultra-Low Temperature Freezer
- Suggestions for use: Due to the small volume, it is recommended to wait until the temperature in the refrigerator is stable for a period of time before placing the items. Add items in small amounts multiple times, so the temperature will drop faster
- Please read the instructions carefully before use. There may be overtemperature alarm or error code displayed during use. Please refer to the instructions and mail on Amazon at any time.
- Machine operation logic: When the refrigerator is opened and starts to cool down, the overtemperature alarm will not be activated. When the temperature reaches the set temperature, the overtemperature alarm is automatically enabled. If the temperature exceeds the set temperature +/-10 degrees, the alarm will be generated. Please put items in small amounts several times while using
- Available effective capacity 22L, upgrade Stirling compressor, temperature range can be adjusted 18°C ~86°C (64.4 ° F ~-122.8 ° F), voltage range 12V/24V/110V/220V can be used, can use power supply and battery power supply, easy handling, stable temperature, Can be customized to -87°C(-124.6 ° F),
