Larger cabinet for more storage combines with dual refrigeration systems for maximum protection

Wood Dale, IL- April 4, 2011 – SANYO North America Corporation (SANYO) Biomedical Solutions Division announces its new, larger 25.7-cubic foot Twin Guard Series™ -86°C Ultralow Temperature Freezer, the MDF-U700VXC, featuring Dual° Cool™ technology. The Twin Guard Series™ is designed to preserve the most sensitive, high-value biologicals and serves as the ideal critical storage appliance in repositories and medical research facilities. Allowing more flexibility in storage space, up to 576 boxes (2-inch), the MDF-U700VXC is available now through SANYO Biomedical sales representatives.

Joe Laport, Senior Product Manager, Biomedical Solutions Division stated, “A lifetime of work goes into a freezer and can equal hundreds of thousands of dollars of research. With this investment of time and money, researchers are looking for peace of mind. The new MDF-U700VXC, with its larger cabinet size and ability to provide maximum security for these high-value biologicals will be a welcome addition to many facilities.”

Twin Guard Refrigeration System
The MDF-U700VXC employs advanced Dual° Cool™ technology to maintain ultra-low temperatures by using two completely independent one-compressor, autocascade cooling systems. The system offers a way to securely store biological samples by serving as a fail-safe mechanism, with two independent refrigeration circuits that include a closed-loop, cold-wall evaporator configured parallel one to the other. In the unlikely event that a compressor fails, the remaining compressor will automatically continue to keep the interior chamber at a minimum of -65°C for an indefinite period of time. The technology allows more time for samples to be saved over traditional backup systems. An optional LN2 or CO2 back-up system is also available to offer additional protection.

SANYO-designed new generation Cool Safe™ refrigeration compressors also feature innovative refrigerant feedback processes to reduce compressor temperature, extending compressor life and minimizing heat output.

EcoMode™ and Energy Efficiency
A unique EcoMode™ deploys both systems in alternating cycles to maintain -86°C and reduce energy consumption in response to cooling demands. The evaporator coils have also been strategically embedded in SANYO’s patented VIP™ PLUS vacuum insulated, thin-wall panel cabinet to deliver both the best temperature uniformity at all shelf levels as well as maximizing interior storage space. EcoMode™ is recommended and capable of handling 90-95% of applications.

Because of the two-in-one freezer design, no additional backup freezer or its additional footprint and energy use is necessary.

Advanced Control and Monitoring
Freezer functions are made simple through an integrated microprocessor-based control system featuring a high resolution LCD information center. The control and information center includes comprehensive setpoint, alarm, monitoring, diagnostic and communications functions for enhanced operability and visibility. The combination of these systems allows for uniform ultra-low temperature to be achieved.

Other Standard SANYO Features
The MDF-U700VXC is also equipped with standard industry and SANYO features, such as:


  • SANYO-patented V.I.P. Plus™ vacuum insulation panel cabinet construction
  • Insulated and gasketed inner doors that seal inside
