Cooling Performance


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

The MDF-DU901VHL-PE VIP ECO -86°C ultra low temperature freezer provides maximum sample storage capacity within an optimum footprint combined with natural refrigerants to minimise energy consumption, reduce environmental impact and save money.

Efficient Refrigeration

Naturally occurring hydrocarbon (HC) 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.

Inverter Technology

The MDF-DU901VHL-PE VIP ECO ULT Freezer contains Inverter Compressors that maximise cooling performance under different conditions, and contribute to reducing the energy consumption of the freezer.

Intelligent Interface

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.

Environmentally Friendly

Ideal for laboratories looking to reduce their carbon footprint and environmental impact to comply with sustainability policies.

Uniform Sample Storage

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

Easy Data Monitoring

Important information such as freezer temperature, door opening times and alarm history is logged for monitoring in GLP applications.

Inverter Compressors

While conventional freezers use single speed compressors which cycle on and off, the MDF-DU901VHL-PE 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.

Efficient Sample Storage

The combination of VIP PLUS vacuum insulation and an enhanced cabinet design with two insulated inner doors, ensures optimum temperature uniformity, while the reduced wall thickness maximizes storage capacity. 

PHC Europe B.V. also offers the MDF-DU502VH-PE which has a capacity of 528 litres and the MDF-DU702VH-PE which has a capacity of 728 litres.


Cryo Glove

Combining the Cryo glove 400 with our ULT freezer is an essential practice that prioritizes safety, sample integrity, precision, and adherence to industry standards. It's a small investment that yields significant benefits for both you and your research or laboratory work.
