Sanyo MDF-U500VXC, MDF-U700VXC manual Twin Guard Series Green Features

Twin Guard Series™ Green Features

	Because modern laboratories are energy-intensive, SANYO has developed a corporate-wide energy savings and
product	environmental impact approach to new product development. The Twin Guard Series		freezers offer significant benefits
GREEN		™

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.

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™ Green 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.
