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).

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.
