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

The PanasonicTwin Guard® Series satisfies the industry demand for safe, longterm 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, theTwin Guard® Series is ideal for storage 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 Freezer surpasses 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 to sub-component failure associated with conventional cascade systems configured of mutually dependent highand low-stage systems.

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

•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 system 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 systems in overlapping cycles to maintain -86°C and to reduce energy consumption by as much as 15% compared to conventional cascade systems

•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.

•Panasonic-designed Cool Safe refrigeration compressors feature innovative refrigerant feedback processes to reduce compressor temperature,

thereby extending compressor life and minimizing heat output.

Twin Guard® Series Green Features

Because modern laboratories are energy-intensive, Panasonic has developed a corporate-wide energy savings and environmental impact approach to new product development. The Twin Guard® Series freezers offer significant benefits through a balance of refrigeration power, cabinet construction and intelligent control over all functions.

Eco Friendly Technology

•Panasonic freezers are designed to support LEED certification associated with the U.S. Green Building Council recommendations.

•Components are compliant with RoHS directives on the use of hazardous materials in electrical and electronic equipment.

•Noise reduction and operating cost efficiencies are integrated into the refrigeration system.

•Heat output is limited to minimize the impact on facility HVAC demands.

•A microprocessor controller oversees the refrigeration system to regulate cooling cycles, reducing energy consumption.

•Panasonic Cool Safe compressor technology for lower compressor heat internally and externally for lower HVAC loads.

Panasonic is conscious of the need to protect our environment and conserve energy. As a corporate pioneer in life science laboratory equipment and appliances, and as a global source of solutions ranging from energy management to solar power and alternative energies, Panasonic remains committed to providing the best possible laboratory equipment for research and clinical needs.

Uniformity Performance

The placement of evaporator surfaces within the cabinet walls achieve exceptional documented ultra-low temperature uniformity, across the entire operational range of -50°C to -86°C thereby permitting investigators more freedom in placing valuable cell lines and biologicals within the interior cabinet, and assuring uniform cell viability when harvesting products from the ultra-low archive.

CFC Free Refrigerants

Panasonic was the first ultra-low freezer manufacturer to employ non-HCFC R508 low-stage refrigerant, now recognized as today’s industry standard and widely available.This non-proprietary refrigerant is available to refrigeration service professionals on the open market.

The high stage refrigerant is readily available to refrigeration professionals on the open market as well.

Energy Efficient

With a capacity of up to 57,600 two-inch vials in fiberboard boxes, the energy-saving advantages of this efficient Panasonic system extend to lower per-unit storage costs regardless

of the preferred inventory configuration.
