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.

Main features:

• 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
