MDF-DU700VH

Effective capacity
728L
Cooling Performance
-86℃

Features

Large Capacity Ultra-Low Temperature Freezer with Non-Freon HC Refrigerant

Up to 50% reduction in energy consumption
Heat Exchange Design

A new heat exchange design provides greater surface area contact at critical points in the refrigeration system.
This improves overall efficiency and reduces compressor running time for lower energy consumption.

Automatic Compressor Cycling

Compressor ON-OFF cycles are regulated automatically in response to cooling demand to minimize compressor running time and to save energy.

Natural Refrigerants

Natural hydrocarbon refrigerants provide more efficient cooling due to their high latent heat of evaporation. As a result, smaller compressors can be used leading to greater energy efficiency.
With exceptionally low global warming potential natural refrigerants are also better for the environment.

High efficiency insulation using V.I.P. technology
MDF-U700VH is equipped with a 6 times stronger thermal resistance VIP PLUS while keeping the same wall thickness but with more rigid foam polyurethane.
User-friendly design

Various alarms including high/low temperatures, door ajar, power failure alarm and part replacement notification help to keep samples safe even in an emergency.

Installation space
The VIP panel reduced the cabinet wall thickness from 140mm to 70mm and achieved nearly 30% more storage capacity than conventionally insulated freezers, all without increasing its footprint.
Improved air seal heat resistance structure

To allow the eco mode, and to reduce the frosting, the chamber has a well sealed structure.

Status Alert

Unconventional operation can cause malfunctions. Function control monitor notifies the unconventional operation to prevent the problems and helps the safe operation.
It always monitors the operation, and the flash lamp notifies the drops in the voltage, an abnormality of the temperature rise when the ambient temp is over 35˚C, lower than approximately 0˚C,and overload operation. It also notifies the time of battery replacement, and the door status.
The status of these alarms and indicators will be shown on the control panel.

Vacuum release port

The vacuum release port allows smooth door openings. The door seal is tightened by a negative pressure generated from the temperature difference between inside the chamber and the ambient environment.

*If the port is kept open, the air intake hole get frozen and clogged, and will not allow the door to open smoothly. We recommend to keep it closed unless it is neccessory.
Door latch

The outer door latch closes smoothly with a single-hand action over a cam action bearing. The outer door can be secured with an independent padlock provided by customer.

Clip-on grill slide type filter

The condenser filter is situated at the bottom right corner of the front panel to allow easier removal and cleaning.
