[CX9230] Smart Chiller Controller


[CX9230] Smart Chiller Controller
 
 
for Reciprocating and Scroll Compressors(Chiller and CDU) and Etc.
- Super PID Control Algorithm
- Dual Sensor Input Processing
- Powerful Trip Data Log
- Various Analog Outputs
- Multilanguage Support
- Flexible and Reasonable Choice
*The Wolrd Best High Precision Super PID Control Algorithm
With super PID control algorithm developed by Dotech's innovative technologies, the
precise ±0.1℃ control based on auto tuning is provided at unbelievable price.
CX9230 transforms your chiller into a smart one.

*Dual Sensor Input Processing
Dual sensors culminated by Dotech's temperature control technologies and knowhows measure
the inlet and outlet temperatures and remove the noise rapidly and elaborately.
Sensored temperatures set according to each proportion enables an ideal temperature control.

* Powerful Trip Data Log
Like DX Series, CX has a powerful trip data log. Up to 100 events can be traced and operators can
handle the situations flexibly and exactly.

* Various Analog Outputs
2-channel analog outputs(4~20mA) are for heating/cooling control and can be applied to
computed heating/cooling or condenser fan control.
SSR control output can be set easily.

* Multilangual Support
Multilanguages are supported(Korean and English).
*Flexible and Reasonable Choice at Competitive Price
Depending on the requirements and applications, the desired one can be selected among the specified models.
