MDF-DU700ZH-PE

The PHCbi MDF-DU700ZH-PE FrostLess ULT freezer is designed for laboratories that require high-capacity ultra-low temperature storage with reduced frost build-up, lower maintenance effort, and improved energy efficiency.

With a storage volume of 725 litres, FrostLess technology, and hydrocarbon refrigerants, this model supports reliable long-term sample preservation while helping reduce environmental impact.

FrostLess technology

The FrostLess design is developed to suppress frost growth on the inner door surface and reduce the time needed for manual maintenance. The improved insulation concept supports smoother operation and better sample accessibility during routine use.

On the current PHC Europe product page, PHCbi states that the new thermal insulation design for the inner doors reduces time to defrost by 60%. :contentReference[oaicite:2]{index=2}

New thermal insulation

The inner doors are redesigned with VIP panels and a new thermal insulation concept to suppress frost growth more effectively. This helps maintain stable storage conditions while supporting efficient day-to-day operation.

PHCbi lists this model at 725 litres with a temperature control range of -40 °C to -86 °C on the live product page. :contentReference[oaicite:3]{index=3}

Inverter compressor performance

Unlike conventional freezers with single-speed compressors, the FrostLess ULT freezer uses inverter compressor technology that can operate at different speeds depending on cooling demand. This helps optimize cooling performance under different laboratory conditions.

PHCbi specifies a cascade refrigeration system with 2 x 920 W compressors and HC refrigerant for this model. :contentReference[oaicite:4]{index=4}

Why this matters

• Improved cooling efficiency
• Reduced power consumption
• Lower heat emission into the laboratory
• Support for sustainability goals

Environmentally friendly sample storage

FrostLess freezers are ideal for laboratories that want to reduce their carbon footprint and align with sustainability policies. Naturally occurring hydrocarbon refrigerants support efficient cooling and reduced energy costs.

The product page describes the freezer as a cost-saving and environmentally friendly solution with reduced frost accumulation. :contentReference[oaicite:5]{index=5}

Main advantages

• Natural refrigerants with reduced environmental impact
• Compact footprint for efficient lab space use
• Lower energy consumption and operational cost
• Reduced frost-related downtime
