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
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 CO

or LN2 backup sys-

• A unique EcoMode deploys both sys­tems in overlapping cycles to maintain

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 signicant benets
through a balance of refrigeration power, cabinet construction and intelligent control over all functions.

Eco Friendly Technology

• Panasonic freezers are designed to
support LEED certication 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

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.
efciencies 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.

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 rst 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.
