TwinCore technology includes two complete and independent refrigeration systems. Unlike a leading brand’s, TwinCore is a true backup and will maintain set point down to -82ºC not just -60C for a few hours. The second compressor acts as a backup, and energy usage is dramatically reduced.
Standard ultra-low freezers rely on a cascade refrigeration system. If this system fails, the freezer and your samples have to be removed in couple of hours. LN2 or CO2 backups only sustain temperatures for approximately 7 hours, and require routine re-filling, maintenance & supervision.
