ANTECH -86℃ DualGuard ULT freezer is designed with two independent refrigerant systems to reassure the valuable samples storing in security and reliable temperature. If one of the compressors partially fails, the other can continue to maintain freezer temperature at -80°C.
DualGuard ULT freezers are also designed to maximize storage samples capacity. 4 upright models with different capacities can meet most of customers' requirements.
-86℃ DualGuard ULT Freezer
Dual Cooling System
The Dual Cooling System Ultra-low Freezer avoids conventional cascade refrigeration technology by using two completely independent one-compressor, auto-cascade cooling systems, each capable of maintaining ultra-low temperatures.
Each refrigeration circuit includes a closed-loop cold-wall evaporator configured in parallel to the other.
Conventional ULT freezers with single or cascade refrigeration circuits cannot work when one compressor fails.
Features
