Twin Guard Series
Because modern laboratories are energy-intensive, SANYO has developed a corporate-wide energy savings and
environmental impact approach to new product development. The Twin Guard Series
GREEN
product
through a balance of refrigeration power, cabinet construction and intelligent control over all functions.
Eco Friendly Technology
• SANYO 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 hazard-
ous materials in electrical and elec-
tronic 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.
• SANYO Cool Safe
compressor
™
technology for lower compressor
heat internally and externally lower
HVAC loads.

Green Features
™
SANYO 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 manage-
ment to solar power and alternative
energies, SANYO remains committed
to providing the best possible labora-
tory equipment for research and
clinical needs.
Uniformity Performance
The placement of evaporator surfaces
within the cabinet walls achieve excep-
tional documented ultra-low temperature
uniformity, thereby permitting investiga-
tors 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 refriger-
ant 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.
SANYO Twin Guard Series
Initiative Program
With a capacity of up to 57 ,600
two-inch vials in fiberboard boxes,
the energy-saving advantages of this
efficient SANYO system extend to
lower per-unit storage costs regardless
of the preferred inventory configuration.
