FrostLess and Energy Efficiency in Ultra-Low Temperature Freezers

PHC's New MDF-DU700ZH reduces "frost" on the surface of the inner door. "Frost" that adheres to the inner door surface is suppressed. This reduces the time required for troublesome defrosting work. 

Natural refrigerants and inverter technology 

MDF-DU700ZH is an ultra-low temperature freezer that also achieves high energy efficiency by using a natural refrigerant (non-Freon) and inverter control. Naturally occurring hydrocarbon (HC) refrigerants have minimal effect on the environment and are compliant with environmental legislation for climate control. Combined with inverter technology, these refrigerants also provide more efficient cooling without compromising cooling performance, ambient tolerance, and recovery speeds following door openings.
