This sensor measures vibrations in the fan/motor set in real time. If abnormal vibration is detected it can send an alarm signal or even stop the fan. This way we will prevent damage to the fan.
OIL / MOTOR TEMPERATURE PROBE
This sensor measures the temperature of the gearbox oil or motor coil. If an excess of temperature occurs in the oil or motor, the probe sends an alarm signal or stops the motor. This prevents possible damage to the motor / geared motor and consequently to the equipment in general.
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.
This heating element is designed to heat the water in the area closest to the cooling tower discharge, thus ensuring that the pumps are not starved of water upon start up. Thanks to this device, the water in the sump is prevented from freezing avoiding damage to hydraulic elements.
The control panel can set the maximum and minimum temperature and the required hysteresis in the sump.
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.
INLET 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.
PACK FOULING MONITORING
The ”Smart Cooling Tower” can detect the accumulation of dirt, lime scale, biological film, etc. within the packing. The control panel monitors the level of fouling and can advise when the pack needs to be cleaned or replaced. This avoids any loss of thermal performance due to fouling
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.
