The Safest Ultra-Low Freezers for Long-Term Storage of Ultra- Critical Biologicals

The SANYO Twin Guard Series™ satisfies the 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 stor- age of sensitive stem cells, embryos, cell lines, and other rare specimens.

Twin Guard Series™ -86 Dual°Cool Refrigeration System

The Twin Guard Series™ Ultra-Low Freez- er avoids conventional cascade refrigera- tion technology by using two completely independent one-compressor, autocas- cade cooling systems, each capable of maintaining ultra-low temperatures.

•Each refrigeration circuit includes a closed-loop cold-wall evaporator con- figured 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 mutu- ally dependent high- and low-stage systems.

•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.

•In the event of a facility power failure

with optional CO2 or LN2 backup sys- tem installed, the freezer will maintain -65°C storage temperature for up to

eight hours (CO2 backup system) and -65°C storage temperature for up to 15 hours (LN2 backup system).

•A unique EcoMode™ deploys both sys- tems in overlapping cycles to maintain -86°C and to reduce energy consump- tion by as much as 15%.

•Evaporator coils embedded in the pat- ented, high-tech, SANYO V.I.P. 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 SANYO-designed Cool Safe™ refrigeration compressors feature inno- vative refrigerant feedback processes to reduce compressor temperature, thereby extending compressor life and minimizing heat output.

Independent systems efficient ultra-low cooling is achieved through two independent evaporator circuits surrounding the interior chamber.

MDF-U500VXC, MDF-U700VXC specifications

The Sanyo MDF-U700VXC and MDF-U500VXC models are compact and efficient commercial freezers designed for laboratory and medical applications. These products are lauded for their reliability, precision temperature control, and user-friendly features. Both units cater to institutions that require secure and consistent storage for temperature-sensitive items.

One of the standout features of the Sanyo MDF-U700VXC and MDF-U500VXC is their advanced cooling technology. They utilize a hybrid refrigeration system that combines both natural refrigerants and cutting-edge compressor technology. This not only ensures a stable cooling environment but also minimizes environmental impact by using eco-friendly refrigerants. The temperature range for both models typically spans from -20°C to -30°C, making them ideal for preserving biological samples, pharmaceuticals, and other sensitive materials.

Another prominent characteristic is the temperature accuracy and uniformity. Both units are equipped with sophisticated microprocessor-controlled temperature management systems that maintain precise temperature levels. Additionally, integrated alarms and monitoring systems provide alerts in case of temperature fluctuations, ensuring that the stored contents remain undisturbed and protected. This feature is crucial in laboratory environments where product integrity is paramount.

The MDF-U700VXC has a larger capacity compared to the MDF-U500VXC, appealing to users who need to store a significant number of samples or larger items. However, both models are designed with space efficiency in mind, featuring adjustable shelving and a well-organized interior that allows easy access to stored materials. The exterior is crafted for durability, with a robust construction that can withstand the rigors of daily use in busy environments.

Energy efficiency is another key consideration in both models. They are designed to minimize power consumption while maintaining optimal performance, which is a critical factor in reducing operational costs for laboratories and medical facilities.

Both Sanyo models feature user-friendly interfaces, making setup and operation straightforward for staff members. Optional accessories such as external temperature recorders can further enhance usability and compliance with safety regulations.

To summarize, the Sanyo MDF-U700VXC and MDF-U500VXC represent cutting-edge solutions for temperature-sensitive storage. Their advanced cooling technologies, precise temperature control, user-friendly design, and energy efficiency make them essential assets for any laboratory or medical facility striving for excellence in sample preservation.
