•Cascaded medium and Low temperature racks meet load requirement of large/medium size supermarkets and cold rooms.
•Medium temperature system uses R134a while low temperature system uses CO2 (R744)
•CO2 is a natural and environment friendly refrigerant, ODP=1, GWP=1, nonpoisonous and nonflammable. 
•CO2 has good flow characteristics and high unit volume cooling capacity. It significantly reduces the size of tube and all components in the system compared with traditional freon system. 
•MT system has digital energy regulating features and LT system has inverter. It can provide stepless capacity modulation within the load range of 20%~100%. This feature saves energy and reduces on-off cycle times of compressor and temperature fluctuation of cold room. 
•Stably controlled condensing temperature of LT system makes system reliable.
•Auxiliary refrigeration unit prevents the LT system from over-high pressure when system in long time idle.
