MDF-U33V

Features

EVOLUTIONARY DESIGN

•SANYO V.I.P.™ Evolution Series -86˚C ultra-low temperature freezers use patented revolutionary vacuum insula- tion cabinet construction that reduces the wall thickness from 14cm to 7cm (5.5” to 2.7”) and achieves up to 30% more storage capacity than a conven- tionally insulated freezer without increas- ing the footprint.

•The newly developed refrigeration system and the freezer structure offer a quiet experimental environment.

•Achieves 12% higher energy conser- vation than previous model. (115V, 60Hz)

•The newly developed back cover com- bined with new aerodynamically design- ed and placed components in the refrigeration compartment provide superior air flow, making it possible to drastically reduce the stress on the freezer and contributing to excellent

durability.

SAFETY

•Alarm lamp and buzzer offer secure warning of power failure or abnormal temperature increase.

•High and low temperature warning provides an audible and visual alarm

when the temperature deviates more than ±5˚C to ±20˚C (adjustable) from the set point.

•Alarm ring-back function ensures that buzzer will resume operation, should alarm conditions continue after it is silenced.

•Microprocessor-controlled filter-clog check function protects the refrigeration circuit.

•The rugged, one-handed outer door latch has a hole to allow a padlock to securely protect valuable samples.

•Control panel with digital display for easy operation.

*Cooling performance is indicated by the temperature reached at the center of the freezer (at ambient temperature of 30°C with no load). In order to use the freezer at a stable temperature for a long time, it is recommended that the temperature be set to at least 5°C higher than the indicated lowest temperature.

In addition, depending on the usage conditions, it may not be possible to reach the indicated lowest temperature.

Caution: SANYO guarantees the product under certain warranty condi- tions. SANYO in no way shall be responsible for any loss of content or damage to content.

•Two independent and insulated inner doors with gaskets prevent cold air leakage.

RELIABILITY

•Status Alert (Condition monitor) Monitors ambient and system conditions continuously and notifies of any abnormalities before a problem happens.

ACCESSIBILITY

•A beak style inner door latch tightly closes the inner door against the freezer

frame. It also helps make opening and closing the door smoother.

•The condenser filter is situated at the bottom right side of the front panel to make filter removal and cleaning easier.
