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.
