The control panel oversees and monitors the autonomous management of the ”Smart Cooling Tower”, based on the set parameters and the information gathered from the various probes installed.
The main component is a PLC that integrates algorithms PID to optimize the power consumption of the fan motors and circulating pumps motors, according to the set-point values introduced. Please note that the circulating pumps are only available on our closed-circuit tower range.
The control panel comes as standard with a 7” touch screen, allowing full operational control of the ”Smart Cooling Tower”. As an optional extra the screen size can be increased to 10”.
TEMPERATURE AND HUMIDITY PROBE (STHE)
The Temperature and Humidity sensor monitors the outdoor conditions around the cooling tower, making it possible to remotely appraise the performance of the ”Smart Cooling Tower”, based on the design criteria.
TEMPERATURE PROBE IN THE BASIN
It is installed at the sump to monitor the cold-water temperature . This probe controls the operation of the electric heater in the sump.
VARIABLE SPEED DRIVES (VSD)
VSD´s adjusts the rotation speed of the fan motors according to the parameters set on the control panel. This device integrates the control software with PID algorithms, which optimize energy consumption and recommend preventive maintenance.
The VSD is able to monitor the following useful information about the motor:
- Motor rotation speed.
- Current through the motor coils.
- Real electric consumption, etc.
OUTLET TEMPERATURE PROBES
Inlet temperatures are constantly monitored using built in temperature probes. The control panel uses the temperatures obtained to optimise the tower functionality and control using the VSD.
PRIMARY CIRCUIT PUMPING CONTROL
Regulation of the primary circuit pumping according to the process parameters.
PRIMARY: Allows accurate monitoring of the process water flow rate.
WATER LEVEL CONTROL
This sensor is located in the water basin and constantly monitors the water level and compares it against the set high and low level parameters. The sensor will send high and low level alarms to the control panel should the water level fall out of the set parameters, preventing the sump from draining down or overflowing. Additionally, in the event of a low level alarm the control panel will switch off the electric heater so as not to damage the casing. When the level is normal the equipment works with no restriction.
