MDF-U730 / Auto Defrost
General Purpose Storage - Maintenance Free
• Storage at -30°C with auto-defrost with consistent
temperature control below -20°C during defrost cycle.
• Maintenance free storage - no end user intervention to
defrost unit and clean-up condensate.
• Precision temperature uniformity throughout chamber due
to forced air circulation with dual fans.
Forced-Air Circulation with Auto-Defrost of Evaporator
• Evaporator (Cooling Coils) provide the cooling effect and is
located at the top of the inner chamber.
• Air flow inlets and outlets direct the air flow across the
evaporator to cool the air.
• Dual Circulation fans add to excellent overall uniformity
(uniform temperatures) inside the cabinet.
• Evaporator heater is activated during defrosting cycle to
turn frost into water. The water drains out the back of unit
into a condensate pan. The water (condensate) is eventually
evaporated into the air by a heater in the condensate pan,
making the unit maintenance free for the end user in terms
of defrosting and dealing with the melted condensate (water).
Enzyme Storage Freezer
Bins (MDF-U730M Only)
The optional full storage system, Model #: 730MFB
creates a flexible and convenient inventory system
for enzymes and many other types of samples. The
total system includes 14 storage bins and additional
wire shelving.
MDF-U730M / Manual Defrost
Enzyme & Biologics Preservation
• Storage at -30°C and -20°C easily with
constant stable control.
• Uniform temperatures through out chamber
using Full Cold Wall construction.
• Because there is no defrost cycle, the inner
chamber temperature offers outstanding
uniformity and stability.
Full Cold Wall Design with Manual Defrost
• Unlike many other cold wall freezers, SANYO locates
evaporators in the walls not only along both sides and the
back of the chamber, but also on the top and the bottom of
the chamber to ensure maximum cooling performance.
• With no air flow fans inside the chamber only natural
convection of any temperature difference will move the air.
• Shelves for product storage have full flexibility in placement.
• Because there is no defrost cycle, from time to time
manual defrosting of the inner chamber is necessary.
