MDF-U730 / Auto Defrost  
MDF-U730M / Manual 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.  
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.  
• 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 r in terms  
of defrosting sate (water).  
Full ColdWall 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.
