General Features
NKT-T4 series air-cooled package type chiller units are equipped with four scroll compressors in an independent tandem structure. These series has 4 compressors and two independent refrigeration circuits. Therefore compressors work according to the heat load which means that working with 4 step control (%25…%100), additionally do not need to shut down the unit when there is a maintenance. 3 compressors can works even if there is a maintenance on one compressor. Short maintenance period, easy operation, easy to use color display LCD Screen and integrated hydraulic modules and sensitive temperature precious are general features. NKT-T2 series range of cooling capacity between 65.7 – 498 kW.
