Cost-saving, environmentally friendly sample storage with reduced frost accumulation.
The MDF-DU700ZH FrostLess -86°C Upright Freezers with reduced frost build-up on the inner doors. Provides optimum sample storage capacity within a compact footprint combined with natural refrigerants to minimise energy consumption, reduce environmental impact and save money.
Inverter Compressors
While conventional freezers use single speed compressors which cycle on and off, the MDF-DU500ZH-PE freezer contains inverter compressor that can run at different speeds to maximise cooling performance under different conditions. Combined with hydrocarbon refrigerants, there compressors ensure the most efficient energy use and reduced heat output.
FrostLess Technology
The improved packing, insulation materials, and the heated pipe frame of the inner door gasket result in reduced manual labor for freezer maintenance. Less ice will build up on the inner doors, and the need for defrosting the freezer is reduced.
Test Conditions
Environment Condition:
Temp./Humidity: 30°C/80%
Door Opening/Closing: 150 times, 30sec/n
Period: 30 days.
No Load
Reducing Frost Growth
The new FrostLess freezers from PHCbi minimise frost build up and with that the time needed for regular maintenance. Reducing frost buildup is critical for smooth running of the freezer, accessibility of the samples and preventing damage of samples.
New Thermal Insulation
The new design of the inner doors with New VIP panels inner door [84.5mm] and the new thermal insulation technology of the frame suppresses frost growth.
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 [6.1 / 6.9 kWh/day]*1 and energy costs.
