Overview

M-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 the -80℃. Valuable and irreplaceable samples can always be securely with the highest confidence even if the compressor fails.

Two High-efficiency Refrigeration Systems

Two high-efficiency refrigeration sytems work independently,if one system fails,the other can still maintain the temperature at -80℃，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 more balanced temperature,thuseffectively saving energy.

Applicable to Various Power Supply Environments

It can work normally under various power supply environments such as 110V60Hz, 220V50Hz, 220V60Hz, ect.

Stable Internal Temperature

Standard SECOP compressors maintain a stable -86℃ ultra low temperature environment, that increases efficient sample storage.

Extreme Labor-saving

Ergonomic handle, smooth track and high-precision pressure relief valve make it easier to open and close the door.

Human-oriented

· 3 division plates are equipped inside to divide the storage area into 4 layers for convenient sample placement; 2 internal doors are also equipped to reducing frosting caused by door opening;

· Stainless steel (SUS304) as the internal material, is durable and easy-to -clean;

· Equipped with 4 heavy casters and 2 leveling feet for easy movement and fixation of the equipment.
