CONDENSER FANS
CONDENSER FANS MOTOR
MICROPROCESSOR CONTROLLER
Condenser fans are constructed with aluminum or steel or PPG or PAG blades on steel hubs with direct driven motors.
All fans are statically and dynamically balanced to operate at minimum noise and vibration. Fan blades are designed
with appropriate pitch angle which result in maximum airflow through the condenser coil.
All fan motors shall be three phase with '' F ‘' class winding insulation and ball or roller bearings for high ambient
application.
Inherent thermal protection of automatic reset type. ( optional )
( optional )
The control works on the state of art microprocessor technology. This controller monitors analog and digital inputs to
achieve precise control & safety functions of the unit.
The software works on the proportional Integral (PI) algorithm for precise control logic.
The simple to use push button keyboard allows to access the operating conditions, control set points & alarm history
clearly displayed on a multi-line back illuminated LCD panel.
An easy to install
serial port/modemoption
allows remote monitoring of the operating parameters. With corresponding
windows software, the system allows data to be viewed in tabular or graphic format and as well interact with system set
up.
Display Information:
In the normal operating mode the 20 x 4 characters LCD panel display the system status, the temperature of the water
inlet & outlet, the set point, run time of the compressor & the alarm history.
Easily accessible measurements for each circuit include the following
suction and discharge pressure
·
oil pressure
·
compressor status
·
fan status
·
liquid line solenoid status
·
Unit/Compressor run time
The control temperature is continuously displayed on the 3 Digit 7 segments LED Display. The 3 LED lights indicate the
Power ON, Menu adjustment and Fault .
System Protection:
·
The following system protection is provided to ensure system reliability:
·
Compressor winding overheating
·
Low suction pressure
·
High discharge pressure
·
Freeze protection
·
Low oil pressure
·
Sensor error
·
Time delay - Anti recycle time for compressor
