Purpose-Built Cold Chain Storage
PHCbi brand ULT freezers are engineered from the inside out to create, maintain, and restore precise temperatures necessary for safe product storage. Our purpose-built ultra-low temperature freezers are designed for temperature uniformity and stability.
The MDF-DU700ZHA-PA FrostLess ultra-low temperature upright freezer provides reliable temperatures as low as -86°C. It is engineered to mitigate frost buildup more than our category-leading models while maintaining the reliability and energy efficiency that today's laboratories require.
Frost Resistance and Mitigation
Frost accumulation may cause damage and deterioration of freezer components. The all-new thermal insulation design of the MDF-DU700ZHA-PA prevents large amounts of frost buildup from accumulating outside the inner doors. Reduced frost buildup minimizes stress on the outer door and latching mechanism, helping preserve optimal performance.
Using the residual heat from the refrigeration system, the perimeter heater under the gasket allows for gentle warmth, further reducing ice buildup on the door gasket.
Overall, reduced frost buildup in the PHCbi brand FrostLess ULT helps reduce manual labor spent during freezer defrosting, improves lab workflow, and ensures freezer performance, leading to reduced maintenance requirements.
VIP® Plus Insulation
The MDF-DU700ZHA-PA ULT freezer is constructed with VIP Plus vacuum insulation on the inner doors for improved insulation performance and reduced frost buildup.
In addition, the shape and materials of the inner door frame packing have been revamped to further improve heat insulation performance, greatly suppressing the formation of frost, including frost formation around the packing.
Natural Refrigerants
With natural refrigerants, the PHCbi brand FrostLess ULT delivers more energy efficient and dependable ultra-low temperature storage. The use of environmentally friendly, natural refrigerants minimizes environmental impact without compromising ultra-low temperature performance, helping achieve sustainability goals. Natural refrigerants eliminate older ozone depleting refrigerants, reduce global warming potential and increase cooling efficiency.
Energy Efficiency
The use of energy efficient, natural refrigerants in the PHCbi brand FrostLess ULT combined with an inverter-controlled compressor, lowers operational costs, environmental impact, and total cost of ownership. The MDF-DU700ZHA-PA FrostLess ULT has a daily energy usage of 7.9 kWh (steady state at -80°C in a 23°C ambient), a reduction of approximately 32% compared to conventional models. i
Security, Control, and Monitoring
An eye-level, door-mounted color LCD touchscreen allows full user control while the USB port makes transferring logged data to a PC convenient. All performance attributes are displayed, and an internal temperature log is expressed in graphic form over time. Optional cloud services for remote monitoring are available.
EZlatch™ Ergonomic Door Closure with Integrated Lock
The EZlatch is our holistic approach to accessing the freezer. This feature is engineered to tolerate frequent door openings and simplify freezer access through one-handed operation that maintains the integrity of the door seal.
The patent pending EZlatch is engineered to accommodate frequent door openings and to control frost associated with extreme temperature differentials in high humidity environments. This combination of product and process maintains the integrity of the door seal to ensure energy efficiency.
