Purpose-Built Cold Chain Storage

PHCbi brand ultra-low temperature (ULT) VIP® ECO freezers are engineered from the inside out to create, maintain, and restore precise temperatures. Our purpose-built ultra-low temperature freezers achieve and maintain temperature uniformity and stability not commonly found with household or commercial cabinets.

The MDF-DU901VHA-PA VIP ECO large volume ULT provides reliable temperatures as low as -80°C. The MDF-DU901VHA-PA is part of the VIP ECO Series of ultra-low temperature freezers. PHCbi brand VIP ECO Series ULTs have earned a worldwide reputation for dependable performance in demanding environments where critical materials must be preserved for generations.

High Capacity Storage, Superior Performance, 115V Operation

This large volume high capacity ultra-low temperature upright freezer is ideal for use in biorepositories, research freezer farms and facilities where bulk storage of sensitive biological material is managed. The cabinet orientation holds up to 672, 2" boxes or 448, 3" boxes within 10.79 sq.ft. (~1 sq.m). Powered by a 115V electrical service, performance, reliability and energy efficiency combine to secure valuable biological samples, making it a superior choice for new or replacement installations.

ENERGY STAR® Certified

The VIP ECO Model MDF-DU901VHA-PA has earned ENERGY STAR Certification based on independent testing by third party laboratories. Test results for products submitted to ENERGY STAR can be compared for performance across the competitive market at See PHC Corporation of North America's ENERGY STAR Unique ID 2354277.

Minimum Footprint for Efficient Use of Lab Floor Space

The upright cabinet design includes a patented VIP Plus thin-profile insulation composite which ensures exceptional insulation value while maximizing interior space efficiency and storage capacity. This highly efficient insulation also improves temperature stability following frequent door openings and extends warm-up times during power outages. The efficient volume-to-footprint ratio maximizes use of available floor space while still able to pass through a standard 36" wide doorway.

Reliable Temperature Control Using Natural Refrigerants, Intelligent Compressors

Natural refrigerants minimize environmental impact without compromising ultra-low temperature performance. The robust refrigeration system is powered by a new generation of high performance inverter compressors, designed to maintain the most efficient energy consumption. Energy efficient reserve refrigeration power assures fast temperature recovery following door openings and tolerance for high ambient conditions such as warm labs or hallways. Operating costs are minimized while stored product protection is secured.

EZlatch Ergonomic Design for Quick Access and Positive Door Closure

The patent pending EZlatch door handle is integral to the inventory access system. This feature is engineered to tolerate frequent door openings and control frost associated with extreme temperature differentials, protecting stored samples. Positive latching inner doors supplement the insulation factor of the outer door, maintaining the integrity of the door seal to assure energy efficiency. The ergonomic design permits secure one-handed opening and closing with a minimum of effort. An automatic vacuum relief port permits quick re-entry.

Microprocessor Controller

An integral microprocessor controller combines freezer operation including setpoint security, system monitoring, predictive performance and data logging functions into a single eye-level door display. The large color LCD touchscreen can be controlled with a gloved hand. This password protected, fully functional display includes audio and visual warnings, unit diagnostics, temperature and door opening data. A USB port permits the convenient transfer of operating history as desired.


Large Volume Ultra-Low Freezer

The VIP ECO -86°C ultra-low temperature freezer provides high volume, long term sample storage capability within an optimum footprint. Natural refrigerants minimize energy consumption, reducing environmental impact. Freezer operation is optimally managed by effectively balancing temperature performance and energy management.

VIP ECO Products

VIP ECO Series

The VIP ECO Series ultra-low temperature freezers represent an advance in refrigeration technology and cabinet design required to minimize energy consumption while maintaining a safe, uniform and stable ultra-low environment for life forms. Together with new refrigeration platform based on variable speed inverter compressors and sophisticated control algorithms, the VIP ECO freezer successfully uses of natural refrigerants essential to global sustainability without compromising cooling performance.

VIP ECO freezers include Advanced Frost Control and an EZLatch door design ultimately essential to better energy efficiency in real-world conditions and are available in three cabinet sizes.

Performance and Reliability

Reliable Cooling and Temperature Performance

The robust refrigeration system provides dependable cooling and temperature performance through the PHC engineered heat transfer components and time tested natural refrigerants. Reserve refrigeration power assures exceptionally fast temperature recovery following door openings. Performance and reliability are never compromised when it comes to storing your valued samples.

As interior air temperature stabilizes at the desired setpoint, mass storage volume sustains tight temperature uniformity of the load inside the insulated cabinet.
Energy Efficient, Balanced Power

Smart compressors, natural refrigerants and integrated electronics combine to lower your facility’s operating costs. Freezer operation is managed by the practical balance of temperature performance and energy management.

Cascade Reliability

The PHCbi cascade refrigeration platform is based on high-performance compressors designed by PHC specifically for ultra-low temperature applications. The PHCbi cascade system is used on VIP Series upright freezers for temperature storage preferences within a range of -50°C to -86°C. These ULT lab freezers use two compressors in a cascade sequence. Both systems work together, running on uniquely designed refrigeration compressors designed to cool themselves as they operate to achieve ultra-low temperatures.

Ergonomic Design

Opening the door of an ultra-low temperature freezer is not an insignificant event. Due to extreme temperature differentials, users should know the location of stored product inside the freezer to minimize the duration of the door opening. Best practices lead to better chamber uniformity, faster recovery of setpoint temperature and overall longer freezer life as a result of reduced strain.

The PHCbi Advanced Frost Control System

The Advanced Frost Control System is a combination of nine individually engineered components, designed to work together to minimize frost, protect contents and extend freezer life.

1. The Outer Door

The outer door is insulated and mounted on heavy duty oval fastened hinges to permit adjustment throughout the life of the freeer.

2. EZlatch Door Handle

The patent pending PHCbi door handle spans an arc of 45 degrees in total movement for easy operation. The EZlatch is included as a standard feature on the PHCbi VIP ECO -86°C / -80°C Laboratory Freezer Series.

The EZLatch is standard on all VIP ECO Series upright ultra-low temperature freezers.
3. Security

The EZlatch includes an integral lock and a provision for a secondary padlock to restrict access.

4. Mullion Heater

Refrigeration system heat output is diverted to the non-temperature conduction extrusion to resist heat moisture accumulation which can cause frost and ice build-up.

5. Air Space

The outer door design minimizes trapped ambient air between the outer door and inner doors.

6. Inner Doors

Insulated inner doors with gaskets minimize cold air loss during door openings.

7. Heat Breaks

To minimize frost and protect the cabinet seal, all materials at the door/cabinet interface are engineered to reduce passive heat transmission from the outside to the inside and to diminish cold surfaces in contact with moist, ambient air.

8. Gasket Integrity

The outer door gasket is engineered to provide and extra measure of protection from the severe temperature gradient between the room and the chamber interior. A soft durometer gasket creates a multi-point sequence of air pockets to enhance insulation value when the door is closed.

9. Vacuum Relief

The automatic vacuum relief port equalizes pressure and permits the outer door to be opened easily for quick re-entry.
