DAIHAN® Innovation of Ultra Low Temp. Freezing System Ⅰ . Double Security and Power Up - DuoFreez TM Model Ⅱ . Simple, High Efficiency and Green - UniFreez TM Model

Ⅰ . - 95 ℃ DuoFreez TM model ; Double Security & Robustness “ Independent Dual Compressor Freezing System ”

We Offer a Unique High-stability System Powered by Two Independent UniFreez TM System, Which Operates Independently. Normally, Both Compressors would Run and It can Drop The Inner Storage Chamber’s Temperature to -95 ℃ with DuoFreez TM System, in Circumstances of Unexpected Failure of One of The Compressors, The other UniFreez TM System would still Remain Working as a ‘Back-Up’ and Maintains Ultra Low Temperature of -80 ℃ . This Innovative Realizes Utmost Stability and Robustness, Which is Most Important Feature in ULT Freezer for the Customer

Ⅱ . - 86 ℃ UniFreez TM model ; High Efficiency “ Single Compressor Freezing System ”

Most of Ultra Low Temperature Freezers, as Shown in The Following Diagram, Have Two Compressors Which Cooperates with Each Other to Drop The Internal Temperature Down to -86 ℃ and It’s Overall Freezing Mechanism are Quite Complex. However, Our Advanced System, UniFreez TM Only Uses a Single Compressor. Although UniFreez TM Has Just The Single Set of Compressor, Capillary Tube, Condenser, Evaporator. It Ensures The Temperature to Go Down to 86 ℃ by The Help of an Advanced Compressor Control Technology and The Process of Special Refrigerants Mixing. UniFreez TM Overcomes Technical Complexity of The Typical Cascaded Double Compressor System. Simplification of Freezing Mechanism and Electricity Minimizes The Noise, Power Consumption and Operation Failures.
