MDF-U500VX TwinGuard ULT Freezers (-86°C)

Safe and Secure Extra-Large Capacity Ultra-Low Freezer with Dual Cooling System

Secure storage with new dual cooling system

The Dual Cooling System securely stores valuable biological samples using two independent compressors to maintain reliable -86˚C conditions.
If one cooling circuit fails, the other maintains at least -65˚C.

Chamber Temperature Behavior

시간 (hour)	0	1	2	3	4	5	6	7	8	9	10	11	12
상태	Pull-up while a power failure / Single compressor operation (-65°C 유지) / Normal cycle operation (-80°C 설정)

세 가지 상태 비교:

Normal cycle operation (-80°C setting)
Single compressor operation (kept at approx. -65°C)
Pull-up while a power failure

*Unexpected compressor failure will trigger an alert.
*Measured example (AT23˚C, 230V/50Hz, no load). Actual performance may vary.

Independent Systems

Efficient ultra-low cooling is achieved through two independent evaporator circuits (A, B) surrounding the interior chamber.
(View from right rear of unit, -86°C operation)

Intelligent ECO mode operation

“ECO mode” independently controls compressors A and B to optimize operation and minimize energy consumption by monitoring freezer load status.

ECO vs NORMAL Mode Operation

항목	ECO Mode	NORMAL Mode
Compressor Control	Independent (Pattern2, Pattern3)	Simultaneous ON/OFF
Temperature Stability	Maintained at -80°C	Maintained at -80°C
Efficiency	Optimized for load	Standard

*Ambient 30˚C (-80˚C setting).
*Measured example (AT23˚C, 230V/50Hz, no load).

Graphic control panel

Central LCD display enhances visibility and operability.
Data log function retains operation data and transmits to PC via MTR-480-PW interface.
Software installation required for log data transfer.

Microprocessor memory backup ensures recovery after power failure.
Self-diagnostics display error codes if abnormalities occur.

High efficiency insulation using V.I.P. technology

Equipped with VIP PLUS insulation — six times stronger thermal resistance with same wall thickness but improved rigidity using polyurethane foam.

User-friendly design

Multiple alarms (high/low temperature, door ajar, power failure, part replacement) safeguard samples even in emergencies.

Installation space

The VIP panel reduced wall thickness from 140mm to 70mm, increasing storage capacity by ~30% without enlarging the footprint.

Improved air seal heat resistance structure

Enhanced chamber sealing reduces frosting and supports ECO mode operation.

Status Alert

Continuous monitoring detects voltage drops, abnormal temperature rise, overload, and door status.
Flashing lamp and control panel indicators notify users of issues such as high ambient temperature (>35˚C), low ambient (<0˚C), or battery replacement timing.
