centrifugal chillers with large cooling capacity for industrial and
CTXK series Centrifugal Chillers
Cooling Capacity: 1230-7032KW (350-2000RT)
Applications: department stores, hotel, office building,
theatre and cinema, hospital, etc.
Optimum aerodynamic design of the chillers with the most advanced
centrifugal compressor design software from CONCEPTS NREC (USA) and
CFD (computational fluid dynamics) software from Numeca, Belgium .
A wide range of cooling capacity with step-less control from 10% to
A few moving parts and good quality of compressor assure long
service life of more than 25 years.
The impeller is made of special aluminum alloy, characterized by
strength and stability with precisely dynamic balancing test and
The impeller and main shaft is keyless connected, to avoid stress
concentration in key plot and rotor unbalance, ensuring reliable
operation of chiller.
Advanced microprocessor control system can optimize logic control,
improve efficiency of operation and assure reliability of long-term
The microprocessor has more than 30 control and safety functions
and can record failure data and clues on trouble source of last 10
shutdowns. The main control machine has been adopted imported
advanced interference-free parts that guarantee safety and reliable
With RS422 interface, it can realize multi-unit central control,
being connected with the main control machine from clients to
realize remote control for chiller’s start/operation/stop.
The units are of interfretted hermetic structure, with small
dimensions, small occupation area, easy installation and
