KU Series Piston Condensing Unit

KU series piston condensing unit has a place in the field of commercial refrigeration with the unique advantages of piston compression. Its overall box-type structure design allows the unit to maintain a compact appearance while the internal piston compressor can achieve efficient compression of the refrigerant through precise reciprocating motion. Whether it is to cope with the continuous refrigeration needs of small and medium-sized cold storages or to meet the intermittent refrigeration conditions of commercial refrigerators, the unit can provide reliable power for various refrigeration equipment with stable performance and flexible adaptability. It is a refrigeration equipment that takes into account both efficiency and durability. ​
