The Safest Ultra-Low Freezers for Long-Term Storage of UltraCritical Biologicals
The SANYO Twin 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, the Twin 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 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 highand 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 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%.
•Evaporator coils embedded in the patented, 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 innovative 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.

Uniformity Performance
The placement of evaporator surfaces within the cabinet walls achieve exceptional documented ultra-low temperature uniformity, 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
SANYO 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 available to refrigeration professionals
on the open market as well.
