Twin Guard Series Ultra-Low Freezer from Panasonic Healthcare Corporation of North America


The Industry’s Safest, Most Energy Efficient Ultra-Low Storage Solution for High Value Biologicals.

The Panasonic Twin Guard® Series satisfies an industry demand for safe, long-term storage for the most high-valued materials. Two, independent refrigeration systems, combined with optional liquid nitrogen or liquid CO2 back-up systems, offer a circle of protection unmatched in the marketplace. Developed for use with conventional inventory racks and boxes, the Twin Guard Series is ideal for storage of sensitive stem cells, embryos, cell lines, and other rare specimens.

The 18.3/25.7 cu.ft. VIP® insulated MDF-U500VXC/U700VXC include integrated LCD performance monitor and digital controller for comprehensive system management, data logging, remote communications, alarms, predictive performance and validation. Maintenance free, filterless design.

The Twin Guard® Series Ultra-Low Freezer avoids conventional cascade refrigeration technology by using two completely independent one-compressor, autocascade 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.
  • Independent evaporators and cooling fans assure back-up status at all times, eliminating system failure due to sub-component failure in conventional cascade systems configured of mutually dependent high- and low-stage systems.
  • Either circuit will maintain -65°C. In the unlikely event of a compressor failure in one system, the remaining system will automatically maintain a minimum of -65°C for an indefinite period.
  • A unique EcoMode deploys both systems in overlapping cycles to maintain -86°C and to reduce energy consumption by as much as 15%.
  • Evaporator coils embedded in the patented, high-tech, Panasonic VIP® PLUS vacuum-insulated thin-wall cabinet are strategically oriented to deliver the best temperature uniformity at all shelf levels, top-to-bottom and front-to-back.
  • New Panasonic designed Cool Safe refrigeration compressors feature innovative refrigerant feedback processes to reduce compressor temperature, thereby extending compressor life and minimizing heat output.
  • In the event of a facility power failure with optional CO2 or LN2 backup system installed, the freezer will maintain -65°C storage temperature for up to 8 hours.
