-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.
Two independent refrigeration systems in one ULT freezer
