MDF-DU500ZH-PE

The PHCbi FrostLess ULT Freezers are designed for laboratories that want reliable ultra-low temperature storage combined with reduced frost accumulation, lower energy consumption, and a more sustainable operation. The MDF-DU500ZH-PE offers 525 litres of storage capacity and combines compact footprint with advanced cooling performance.

By integrating FrostLess technology, hydrocarbon refrigerants, and inverter compressor performance, this freezer helps reduce maintenance time while supporting efficient long-term sample preservation.

FrostLess technology

The FrostLess design is developed to suppress frost growth on the inner door surface and reduce the amount of manual labour needed for maintenance. By improving the packing, insulation materials, and heated pipe frame of the inner door gasket, frost build-up is significantly reduced.

This means less frequent defrosting, smoother daily operation, and improved access to samples during routine use.

New thermal insulation

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

Improved insulation performance also contributes to reduced energy demand and a lower environmental impact.

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 the cooling demand. This helps optimize cooling performance under different laboratory conditions.

Combined with natural hydrocarbon refrigerants, this results in efficient energy use, reliable pull-down performance, and reduced heat output.

Why this matters

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

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 provide efficient cooling because of their high latent heat of evaporation, which supports both performance and reduced energy costs.

The enhanced cabinet design with chamfered edges also helps optimize laboratory space in multi-freezer environments.

Main advantages

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