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-DU500ZHA-PA FrostLess ultra-low temperature upright freezer provides reliable temperatures as low as -86°C. It is engineered to ensure the reliability and energy efficiency modern laboratories demand with less frost buildup. The cutting-edge thermal insulation design helps combat frost buildup to reduce freezer stress and preserve high performance.
Frost Resistance and Mitigation
Frost accumulation may cause damage and deterioration of freezer components. The all-new thermal insulation design of the MDF-DU500ZHA-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 and helps 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-DU500ZHA-PA ULT freezer is constructed with VIP Plus vacuum insulation on the inner doors for improved insulation performance and reduced frost buildup.
Energy Efficiency
The use of energy efficient 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-DU500ZHA-PA FrostLess ULT has a daily energy usage of 6.6 kWh (steady state at -80°C in a 24°C ambient) or 5.21 kWh/day (steady state at -70°C in a 24°C ambient). i
With natural refrigerants, the PHCbi brand FrostLess ULT delivers more energy efficient and dependable ultra-low temperature storage. Environmentally friendly refrigerants reduce 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.
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 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.
Integrated Lab Monitoring with LabSVIFT®
LabSVIFT is a cloud-based service built to simplify monitoring and performance tracking. LabSVIFT provides 24/7 monitoring*, real-time alerts, and centralized records compliant with FDA 21 CFR Part 11**. LabSVIFT features health check for PHCbi's MDF-DU702VH/VHA, MDF-DU502VH/VHA, VIP Smart, FrostLess and upright TwinGuard models, which evaluates equipment performance health to ensure optimal operation. Health check provides notifications with suggested corrective actions if any irregularities or abnormal conditions are detected. From routine performance checks to remote monitoring on your smartphone or PC, LabSVIFT helps ensure that your freezer is secure and operating at peak performance.
