-86°C Dual Cooling System Ultra Low Freezer Freezer For Laboratory And Medical, UL Certification
AzzotaM-Twindrive -86℃ Ultra Low-Temperature Freezer built up by two independent refrigeration systems and the Dual Cooling Systems offers the highest level of protection; if one system unexpectedly fails, the other can maintain the freezer around -75℃. Valuable and irreplaceable samples can always be secure with the highest confidence, even if the compressor fails.
Two High-efficiency Refrigeration Systems
Two high-efficiency refrigeration systems work independently; if one system fails, the other can still maintain the temperature at -75℃, safe and reliable.
Frequency Conversion Technology
Frequency conversion technology is adopted to control the compressor speed in real-time by adjusting the output frequency to ensure a more balanced temperature, thus effectively saving energy.
Applicable to Various Power Supply Environments
It can work typically under various power supply environments such as 110V60Hz, 220V50Hz, 220V60Hz, etc.
Stable Internal Temperature
Standard SECOP compressors maintain a stable -86℃ ultra-low temperature environment, increasing efficient sample storage.
Extreme Labor-saving
The ergonomic handle, smooth track, and high-precision pressure relief valve make opening and closing the door easier.
Human-oriented
· 3 division plates are equipped inside to divide the storage area into four layers for convenient sample placement; 2 internal doors are also equipped to reduce frosting caused by door opening;
· Stainless steel (SUS304) as the internal material is durable and easy to clean;
· Equipped with four heavy casters and two leveling feet for easy movement and fixation of the equipment.
