An eye level, door mounted color LCD touchscreen allows full user control while the USB port makes transferring logged data to a PC convenient. This full function display panel includes audible and visual warnings, unit diagnostics, temperature and door opening history. All performance attributes are displayed and an internal temperature log is expressed in graphic form over time.

Natural Refrigerants

This Natural Refrigerant -86°C Freezer minimizes environmental impact without jeopardizing ultra-low temperature freezer performance.

EZlatch Ergonomic Design for Quick Access and Positive Door Closure

The patent pending EZlatch is engineered to tolerate frequent door openings, simplify one-handed access and control frost associated with extreme temperature differentials. The EZlatch is the centerpiece of a holistic access and frost mitigation system. This comfortable operation maintains the integrity of the door seal to assure energy efficiency.

Overview

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.

These freezers are available in two upright cabinet sizes and in both 115V and 220V electrical models. All VIP ECO freezers include Advanced Frost Control and an EZLatch door design ultimately essential to better energy efficiency in real-world conditions.

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.

The VIP ECO cabinet features are the same as the TwinGuard freezer shown here, Model MDF-DU702VXC-PA. This image shows one additional shelf to create five levels. This freezer model is equipped with three standard shelves.

The PHCbi Advanced Frost Control System is standard on VIP ECO and TwinGuard freezers. 

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. Removable Gaskets

Multi-point door gaskets create micro air breaks around the face of the cabinet, restricting moisture migration into the cabinet and minimizing frost. Gasket composition withstands extreme relative temperature differentials while remaining flexible, ensuring a full peripheral door seal. The outer door gasket can be easily removed and replaced without tools while the freezer can remain in operation with no downtime.


9. Vacuum Relief

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