VIP ECO ULT Freezers (-86°C)


Effective capacity
Cooling Performance


Cost-saving and environmentally friendly sample storage within an optimal footprint

Both VIP ECO models MDF-DU901VHL, MDF-DU901VHA are large volume high performance -86°C upright freezers ideal for use in biorepositories or facilities where bulk storage of sensitive biological is managed. Natural refrigerants minimise its energy consumption to reduce environmental impact. VIP ECOs allow a footprint of just 1m2 for maximum storage.

Efficient Refrigeration & Environmentally Friendly

Natural hydrocarbon refrigerants provide more efficient cooling due to their high latent heat of evaporation. As well as improved performance this leads to reduced power consumption and energy costs. Ideal for laboratories looking to reduce their carbon footprint and environmental impact to comply with sustainability policies.

Inverter Technology & Uniform Sample Storage

The MDF-DU901VH VIP ECO ULT Freezer contains Inverter Compressors that maximise cooling performance under different conditions, and contribute to reducing the energy consumption of the freezer. While conventional freezers use single speed compressors which cycle on and off, the MDF-DU901VH VIP ECO ULT Freezer contains inverter compressors that can run at different speeds to maximise cooling performance under different conditions. Combined with hydrocarbon refrigerants, these compressors ensure the most efficient energy use and reduced heat output.

Inverter compressors provide optimum stability, while quality of design ensures reliability. Ideal for samples that are sensitive to temperature fluctuations.

Intelligent Interface & Easy Data Monitoring

The EZlatch makes access to stored samples even easier. A colour LCD touch panel allows full user control, even with gloved hands, while the USB port makes transferring logged data to a PC simple and convenient. Important information such as freezer temperature, door opening times and alarm history is logged for monitoring in GLP applications.

Efficient & Flexible Sample Storage

The combination of VIP PLUS vacuum insulation and an enhanced cabinet design with insulated outer door, ensures optimum temperature uniformity, while the reduced wall thickness maximizes storage capacity. Multiple shelf configurations allow a variety of storage options. Organize your samples by transferring your current inventory racks.
