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
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
• Exceptionally uniform and reliable temperature
• User-friendly design and low running costs.
• A remote alarm terminal mounted to connect to an external alarm system.
• Chart recorder is optional
• LN2 backup system or CO2 backup system is optional
